Well, here again is a mushroom I’ve seen a number of times in different locations in the same park. This observation is nice because it shows a few different stages of development. Previously, Darvin suggested Psathyrella carbonicola or pennata. There’s only one image of each online, and both are from Italy. Also, both species are alleged to fruit in burn sites, which this isn’t. Also, they’re described and pictured as a dark brown, while mine are all pale ochre to light brown in youth. Given that they seems to occur rather frequently (at least this season) in this park, it seems an unlikely identification. Arora mentions a P. canoceps that doesn’t fruit in burn sites, but I can’t find any images or good descriptions.

Recognized by sight: This is kind of how they usually look in the forest… In grass or wood chips or open areas they tend to have far less veil remnants!

The Psathyrella monograph for North America is online at the U. of Mich. Here is a link to all of the online books by A. H. Smith.

P. canoceps is on page 182. If you want to try and key it out, the keys start on page 30.
