Fungi of The Rigi

3 June 2017

On the way to the supermarket I saw this large troop of Psathyrella growing on wood mulch in Glenmore St, Wellington, just up the hill from The Rigi. (If you are intrigued by the name The Rigi read more here.)

These were Psathyrella microrhiza. Note the colour change as the caps dry out with age as a result of air replacing water between the hyphae that makes up the cap tissue. This is is known as hygrophanous.

Just as I was about to go I noticed that some of the Psathyrella near the edge of the mulched area, where there was more grass, were more reddish. I grabbed a few without stopping to get a picture. Looking at one of the pictures of the whole area you can just make out these pinkish brown specimens with more conical caps than the Psathyrella microrhiza.

This appears to be Psathyrella bipellis which has a reddish brown cap and stipe. There are a number of Psathyrella species fruiting on wood mulch in Wellington and I need to spend some time and see if I can sort them out.

Amazing what you find on the way to the supermarket!

    I don’t think I’ve ever seen that many mushrooms all together – an army!
