Otari-Wilton’s Bush Annual Foray, 28 May 2017

 

This year the foray was held on a cold damp day in May rather than April. This year has been cooler and consistently wetter then then the last couple of years. This has meant that fungi have been fruiting sporadically over a much longer period of time. Here is what we say today.

Otari-Wilton’s Bush, Sunday 11 May 2014

Another brilliant Sunday, 11 May 2014, at Otari-Wilton’s Bush. This is my fifth foray here this autumn and I am still finding species that I have not seen before.

???????????????????????????????

Porcelain slimecap [Oudemansiell australis] and wood-ear jelly – These species were growing on dead karaka trees, read more here.

???????????????????????????????

In the plant collection garden I made three collections of Psathyrella which I think represent three different species. The first was growing on woodchip mulch. The first is the red-edged roundhead [Psathyrella corrugis = Panaeolus sp. see here]. If you turn the cap upside down and look at the gill edges through a hand lens then the edges should look reddish-brown compared to the rest of the gill. I find it best to do this with sunlight on the gills.

???????????????????????????????

???????????????????????????????

The second species was also on woodchip with the caps a little more conical then the red-edged roundhead and the gill edges are the same colour as the rest of the gill and lack the reddish colouring. This appears very similar to Psathyrella conopila.

???????????????????????????????

???????????????????????????????

The third Psathyrella species was larger and growing in a crevice in the greywacky rock. However this bank had a woodchip mulched garden above and a woodchip mulched path below. This may be a native species.

???????????????????????????????

???????????????????????????????

???????????????????????????????

Here are the three species black spore prints with the native Psathyrella species on the left, Psathyrella corrugis in the middle, and Psathyrella conopilaon the right.

???????????????????????????????

This sturdy little parasol (Lepiota sp.) keeps turning up on the woodchip mulch but I still do not have a name for it.

???????????????????????????????

???????????????????????????????

This much bigger Lepiota was coming up in several clumps in the woodchips. It is the spiny parasol [Lepiota aspera] and I have only seen it once before growing in a chicken run in the Western Hutt hills

17 Otari 2014.05.11

21 Otari 2014.05.11

???????????????????????????????

This little yellow mushroom was growing on the woodchip mulched path. It looks a bit like Leucocoprinus fragilissimus however that species has a ring on its stem and there was no sign of one here. [Note added 22 May 2014: I need to open my eyes as this specimen clearly has brown spores and puts this in Bolbitius and probably Bolbitius vitellinus.]

???????????????????????????????

???????????????????????????????

???????????????????????????????

Weeping widow [Lacramaria lacrymabunda] – Growing on woodchips.

???????????????????????????????

Ruby helmet [Mycena viscidocruenta] – This small red Mycena was growing on woodchips.

???????????????????????????????

This is a species of Gymnopus. It looks very like a Californian species known as Gymnopus “stinkii” and the European Gymnopus brassicolens. It can be recognised by the brown caps with a very pale margin and tough blackish stems.

???????????????????????????????

???????????????????????????????

Charcoal flycap [Amanita nothofagi] – Beneath black beech [Nothofagus solandri].

???????????????????????????????

???????????????????????????????

Cocoa bolete [Tylopylus brunneus ] – Beneath black beech [Nothofagus solandri].

???????????????????????????????

???????????????????????????????

Red-flushed bolete [Xerocomus nothofagi] – The red-flushed bolete was growing under kanaka [Kunzea ericoides].

???????????????????????????????

Hygrocybe blanda [orange waxgill] – growing in leaf litter in the fernery.

???????????????????????????????

???????????????????????????????

Brown-umbrella inkcap [Parasola leiocephala] – This big troop of brown-umbrella inkcaps were growing on woodchip under a dense clump of ferns.

???????????????????????????????

Olive honeycap [Armillaria novaezelandae] – growing on a living tree in the Fernery.

???????????????????????????????

A parasol [Lepiota sp.] – small pure white parasol found in the bush.

???????????????????????????????

???????????????????????????????

Tree swordbelt [Agrocybe parasitica]- The mushrooms are about 3 meters above the ground on tawa [Beilschmiedia tawa].

???????????????????????????????

Bush shank [Heimiomyces neovelutipes] – growing on rotten wood.

???????????????????????????????

Native shitake [Lentinellus novae-zelandiae] – This is the biggest fruiting of native shiitake that I have seen at Otari.

???????????????????????????????

???????????????????????????????

Cloudy funnelcap [Clitocybe nebularis ] at the base of a mamaku / tree fern [Cyathea medullaris] in a grove of mamaku.

???????????????????????????????

???????????????????????????????

Brown-blood helmet [Mycena mariae] – Growing on a dead branch. When the stem is broken it oozes a brown sap.

???????????????????????????????

Jelly-stemmed helmet [Mycena austrororida] – Growing on a dead branch.

???????????????????????????????

Blue-eyed helmet [Mycena interrupta] – Growing on a rotting log.

???????????????????????????????

Orange poreconch [Favolaschia calocera]

84 Otari 2014.05.11

Skull puffball [Calvatia craniiformis] – Growing in leaf litter.

???????????????????????????????

Antrodiella zonata [= Irpex brevis] – This wood decay fungus forms small brackets or flat sheets on the underside of rotting logs. Hanging vertically from the brackets are square-ish flat teeth and it is on these teeth that the spores are produced.

???????????????????????????????

And finally lichens growing on rocks in the alpine garden.

Otari – Wilton’s Bush Fungal Foray 2014

Previous Otari-Wilton’s bush forays: 2011, 2012, and 2013. Below are photos and comments on fungi seen over the last two days, 26-27 April.

Porcelain slimecap [Oudemansiell australis] and wood-ear jelly – These species were growing on dead karaka trees, read more here. Most of the dead trees were heavily colonised by the wood-ear jelly but one was largely colonised by porcelain slimecaps.

???????????????????????????????

Olive-stemmed helmet [Mycena olivaceomarginata] – This is a small grassland species.
???????????????????????????????

Red-edged roundhead [Psathyrella corrugis] – No  photo but read more about this species here [as Panaeolus sp.].

Grey-gilled chalkcap [Russula inquinata] – This a mycorrhizal species found growing in association with black beech [Nothofagus solandri]. Taste is a useful characteristic to separate Russula species tasting either acrid/hot/peppery or mild. The grey-gilled chalkcap is mild.

???????????????????????????????

???????????????????????????????

???????????????????????????????

Cocoa bolete [Tylopylus brunneus] – The cocoa bolete will, if in good condition blue when bruised or cut (see here).

???????????????????????????????

Sociable inkcap [Coprinellus disseminatus] – Growing on a beech stump.

???????????????????????????????

Smooth parasol [Leucoagaricus leucothites] – This species was growing in a garden mulched with gravel. There are a couple of photos of the smooth parasol I took in Marlborough last year here.

???????????????????????????????

Ruby helmet [Mycena viscidocruenta] – This small red Mycena was growing on woodchips. Young fresh specimens have a clear layer of slime on their stems but this disappears as the mushrooms age or if conditions are dry. The ruby helmet also occurs in Australia and there is an excellent photo, by Heino Lepp, at the Australian Botanic Gardens’ Australian Fungi website (here).

???????????????????????????????

Brown birdsnest [Crucibulum laeve] – Growing on woodchip.

???????????????????????????????

Fluted birdsnest [Cyathus striatus] – This larger birdsnest is easy recognised by the dark brown hairy cup with a shiny fluted interior. This is the first record of this species at Otari-Wilton’s Bush.

???????????????????????????????

???????????????????????????????

Fragrant parasol [Lepiota  cristata] – Growing in woodchip and the first record of this species at Otari-Wilton’s Bush.

???????????????????????????????

A webcap [Cortinarius sp.] – This species took me by surprise by growing in a gravel bed as it is a mycorrhizal genus. A quick look around showed several kanuka trees within a couple of meters.

???????????????????????????????

Scarlet roundhead [Leratiomyces ceres = Stropharia aurantiaca] – Read more about this species here.

???????????????????????????????

A parasol [Lepiota sp.] – One of many species of Lepiota present in New Zealand.

???????????????????????????????

???????????????????????????????

A shanklet [Marasmius sp.] – This was growing on the bark of a living kahikatea [Dacrycarpus dacrydioides] in the podocarp / kauri grove by the information centre.

???????????????????????????????

???????????????????????????????

Garlic shanklet [Mycetinis curraniae] – Read more about this species here.

???????????????????????????????

A parasol [Lepiota sp.] – Another parasol in need of a name.

???????????????????????????????

A mushroom [Agaricus sp.] – we recorded this unnamed Agaricus species for the first time at the 2013 foray. It was growing about 3 meters away, on the opposite side of the board walk from where it was found last year (see here).

???????????????????????????????

???????????????????????????????

Olive honeycap [Armillaria novaezelandae] – The olive honeycap was growing on a moribund tree in the Fernery.

???????????????????????????????

Harefoot inkcap [Coprinopsis lagopus] – growing in wood chip mulch.

???????????????????????????????

Split gill [Schizophyllum commune] – this little wood decay was growing on logs used to edge the paths in the Fernery.

???????????????????????????????

???????????????????????????????

Wood-ear jelly [Auricularia cornea] – Read more about this species here.

???????????????????????????????

Orange poreconch [Favolaschia calocera] – Read more about this species here.

???????????????????????????????

A parasol [Lepiota sp.] – small pure white parasol found in the bush.

???????????????????????????????

Bush shank [Heimiomyces neovelutipes] – I have recorded this species several times over the last two years growing on the same log.

???????????????????????????????

???????????????????????????????

Bluing pouch [Psilocybe weraroa = Weraroa novae-zelandiae] – We have known this little dirty white pouch fungus as a species of Weraroa for about 50 years. recent molecular research has seen this genus disestablished and its member species scattered amongst other genera. The placement of this species in Psilocybes is not surprising given the deep blue bruising that occurs when the cap is damaged as can be seen in the photo.

???????????????????????????????

Native shitake [Lentinellus novae-zelandiae] – This species fruits routinely on a number of logs in the bush between the fernery and the car park.

???????????????????????????????

A parasol [Lepiota sp.] – A dark grey to slate blue capped parasol growing in wood chip in the Fernery.

???????????????????????????????

Common scabbard [Volvariella gloiocephala] – no photo

Still working on this little mushroom. Initially I tried to shoe horn it into Hydropus ardesiacus but it has a snuff brown spore print not a white one so I need to start again. It seemed to be growing on the frass in the centre of this cut stump rather than the wood.

???????????????????????????????

???????????????????????????????

Cloudy funnelcap [Clitocybe nebularis] – The cloudy funnelcap has been seen several times over the last few years at different places in the bush.

???????????????????????????????

???????????????????????????????

Tea chalkcap [Russula novae-zelandiae] – I collected this for the first time a week ago  and is recognised by its yellowish brown cap, its  mild taste, and it’s association with kanaka [Kunzea ericoides]

???????????????????????????????

A doilycap [Pluteus sp.] – I managed to get a very faint but distinctly pinkish/brick spore print from this specimen but not sure what, if any described, species it is.

???????????????????????????????

???????????????????????????????

Parachute conch [Campanella tristis] – growing on a well decayed branch in the bush.

???????????????????????????????

???????????????????????????????

Addendum 4 May 2014

Rita Urry, who was on the foray, sent me the following photos which she took at Otari the following weekend.

Otari-Wilton’s Bush, Sunday 20 April 2014

 

On my last foray to Otari- Wilton’s Bush I said that it had been a dry cool summer and autumn was not much better. The rains have now arrived and the Wellington region has had two very wet periods in the last two weeks. Here is the rainfall data for the Karori Sanctuary (aka Zealandia) which is a few kilometres to the south of Otari but in the same catchment. (Rainfall graph generated at Greater Wellington Regional Council web site.)

graph-143563

Otari-Wilton’s Bush has a canopy walkway through the treetops. About 18 months ago the decision was made to kill some of the karaka trees [Corynocarpus laevigatus] although native they are not native to this bush and considered invasive. These trees are long dead, have lost their leaves and are now prime fungi habit. Following the recent rain these trees are festooned in wood-ear jellies [Auricularia cornea].

???????????????????????????????

Although there were many species fruiting they were not abundant and often only one or two mushrooms. However there were several species that I had not seen before: a parasol [Lepiota sp.], brown-umbrella inkcap [Parasola leiocephala]; ruby helmet [Mycena viscidocruenta], olive-stemmed helmet [Mycena olivaceomarginata], Parachute conch [Campanella tristis] and tea chalkcap [Russula novae-zelandiae].

The fungi

A parasol [Lepiota sp.] – This was growing in the leaf litter under the podocarp-kauri stand next to the Information Centre band and was first recoded in April 2013.

Another parasol [Lepiota sp.] – This species was growing in the same habit as the previous species and is the first record for the Otari.

???????????????????????????????

???????????????????????????????

Dark cavalier [Melanoleuca melanoleuca] – Again under the podocarp-kauri stand was a group of three aging and beginning to decay mushrooms which I have tentatively identified as the dark cavalier.

???????????????????????????????

Garlic shanklet [Mycetinis curraniae] – On the bark of living totara [Podocarpus totara].

Brown-umbrella inkcap [Parasola leiocephala] – the brown-umbrella inkcap, growing on woodchips, was segregated from the Japanese-umbrella inkcap. The latter tends to be smaller and paler then the brown-umbrella inkcap.

05 Otari 2014.04.20

???????????????????????????????

Red-edged roundhead [Psathyrella corrugis] – Growing on woodchips. I need to check this identification.

07 Otari 2014.04.20

Harefoot inkcap [Coprinopsis lagopus] – Growing on woodchips.

???????????????????????????????

Charcoal flycap [Amanita nothofagi] – Beneath black beech [Nothofagus solandri]. [Note it has snapped at the base and is lying on its side.]

???????????????????????????????

Sociable inkcap [Coprinellus disseminatus] – growing on dead woody roots.

13 Otari 2014.04.20

Weeping widow [Lacramaria lacrymabunda] – Growing on woodchips.

17 Otari 2014.04.20

Ruby helmet [Mycena viscidocruenta] – This small red Mycena was growing on woodchips. Young fresh specimens have a clear layer of slime on their stems but this disappears as the mushrooms age or if conditions are dry.

???????????????????????????????

???????????????????????????????

Brown birdsnest [Crucibulum laeve] – Growing on larger pieces of woodchip.

???????????????????????????????

Scarlet roundhead [Leratiomyces ceres] – Growing on woodchips.

Olive-stemmed helmet [Mycena olivaceomarginata] – This little Mycena was growing on the Cockayne Lawn.

???????????????????????????????

???????????????????????????????

Wood-ear jelly [Auricularia cornea] – This was seen many times on rotting wood. This specimen, at the base of a dead tree was growing in the bush below the Fernery.

48 Otari 2014.04.20

Olive honeycap [Armillaria novaezelandae] – growing on a living tree in the Fernery.

???????????????????????????????

Orange poreconch [Favolaschia calocera] – This was as common as the wood-ear jelly growing on nearly every dead branch in the bush.

???????????????????????????????

Common scabbards [Volvariella gloiocephala] – Growing on woodchips. The cup or volva at the base of the stem can be seen quite clearly.

43 Otari 2014.04.20

46 Otari 2014.04.20

Parachute conch [Campanella tristis] – This little, greyish conch, has poorly defined gills with ridges running between the radial gill ridges to give a reticulated pattern. This was growing on dead wood and this photo shows the underside of the mushroom.

???????????????????????????????

White mushroom – growing on the dead rachis of a mamaku / tree fern [Cyathea medullaris] frond. I am wondering whether or not this is porcelain slimecap [Oudemansiell australis]. I need to do some work on this one.

51 Otari 2014.04.20

Tea chalkcap [Russula novae-zelandiae] – This tea coloured chalkcap, an ectomycorrhizal species, was growing under kanaka [Kunzea ericoides]. A useful characteristic in Russula is taste. Cut a small piece of tissue, about 2x2x2mm, from the internal flesh or from the gills. Put this piece of mushroom flesh on the tip of your tongue and chew it with your front teeth. Some Russula species are hot/peppery and some mild (have a glass of water handy to rinse with. The tea chalkcap is mild.

Otari – Wilton’s Bush Fungal Foray 2012

You can read more about Otari-Wilton’s Bush at the 2011 foray report and at the Otari Wilton’s Bush website.

This last summer has been notable in being grey and similarly this autumn has not arrived. As a result there a few fungi fruiting at the time of the foray, 21-22 April 2012. Below is the list of what we did see.

Otari garden – an exhibition garden of low growing New Zealand native plants but not native to the local area) mulched with wood chips.

Panaeolus sp. [a roundhead] – on wood chip. These mushrooms are ‘hygrophanous’ that is they change colour as they age – see how the larger mushroom in the top photo is becoming streaked with pale buff area. In the second photo the mushroom on the right is almost completely white. [see note at bottom of this blog]

 

Leratiomyces ceres [scarlet roundhead] – on wood chip. For more on this mushroom go to my blog here.

Agrocybes praecox [garden swordbelt] – on wood chip. For more on this mushroom go to my blog here.

Beech (Nothofagus) grove – this grove was planted as beech is not native to the Wellington peninsular.

Amanita nothofagi [charcoal flycap] – this is an mycorrhizal species which means it is only found growing on the roots of southern beech or teatree. It is related to the scarlet flycap, with its red cap and white warts, seen under pines.

Circular walk from Information Centre – this is an area of original broadleaf-podocarp forest but with an underplanted collection of plants that would be expected in this type of forest.

Micromphale sp. [garlic shanklet] – on bark of living totara. If you cup on of these mushroom in your hands and put your hands over your nose you can smell the distinct odour of gallic.

Clitocybe albida [shoelace funnelcap] – growing on rotten wood with extensive shoelace-like white rhizomorphs can be found through the wood and surrounding litter.

 

Weraroa erythrocephala [scarlet pouch] – in litter in mixed forest

Galerina sp. [a logger] – growing on wood, note the ring on the stem.

 

Panaeolus sp [a roundhead] – (slender brown) in litter in mixed forest

Lentinellus novae-zelandiae [bush shiitake] – on rotting log

 

Conchomyces bursaeformis [ivory conch] – a small, stemless mushroom growing on rotten wood with white gills and pale grey top.

 

Armillaria novaezelandae [olive honeycap] – on rotten wood

Oudemansiella sp. – needs confirmation – on litter. This appears similar to the Oudemansiella described by Ian Hood in 1992. However since then the species of this form described in Oudemansiella have all been transferred to Xerula so there really is not a name for it at this point.

Favolaschia calocera (orange poreconch) – on fallen branches

Hygrocybe blanda [orange waxgill] growing on a bank near kanaka

Other finds

These were found in the Circular walk clower down the valley

Entoloma sulphureum [sulphur pinkgill]

Ileodictyon cibarium [common-basket stinkhorn]

The list was compiled with the assistance of Alison Stringer and Shannon Mortimer.

Note 9 May 2013: I have flicked back and forth over the identity of the little brown mushroom on wood chips that I called Panaeolus sp. I am going to stick my neck out further and suggest it might be Psathyrella corrugis as identified by Jerry Cooper at Nature Watch NZ.
