Observation 10711: Psathyrella corrugis group
When: 2008-09-07
No herbarium specimen

Notes: I did not notice these little mushrooms until I stepped on them! I was sitting at a picnic table photographing some other mushrooms when I looked down and saw one sticking out from under my shoe. At first I thought they looked like Marasmius, but you can see the purple-brown spores on one of the caps.

This one is a mystery to me.

In a mowed grassy area next to a stream.

Used references: Audubon guide. Small, fragile gilled mushroom with purple-black spores and attached gills. The bad news is you probably stepped in something; panaeoli mostly grow on dung.

Look at the first photo carefully, the gills are dark, and mostly the dark color is coming from the spores. So, these are mostly probable a dark spored genus. The detail the look for is on the gill face there, the dark color isn’t quite smooth, but is mottled on the gill face. This is a character of the genus Panaeolus, the spores mature in patches on the gill face, not smoothly. Although this feature isn’t there when very young, and it goes away when very old and spores are everywhere. In the first photo, it looks like this feature is there.

Also Panaeolus as a fragile thin stiped little guy in grass is pretty common.

There was no dung, but many kinds of Panaeolus can be found in grassy areas with no dung present. If I had to guess, I would say Panaeolus over the other genera you mentioned.

Psathyrella, Naematoloma, and Psilocybe are the other suspects here. All include small, fragile mushrooms with attached gills and purple-brown spore print. These genera (and Panaeolus) are in two families, Strophariaceae and Coprinaceae, both of which contain a variety of poisonous and hallucinogenic mushrooms, according to my resources. Stropharia would be larger, with a ring, Gomphidius and Chroogomphus larger with a slimy cap and decurrent gills, and Coprinus would melt rather than produce a powdery spore deposit.

If it wasn’t in dung, it’s probably one of the first three genera mentioned in this comment rather than Panaeolus.
