When: 2007-02-16

Collection location: Howarth Park, Santa Rosa, Sonoma Co., California, USA [Click for map]

Who: Debbie Drechsler (debdrex)

No specimen available

Observed over a period of two days when there was no rain and the temperature went to near 70 degrees fahrenheit. Gills on the younger specimen were a pale tan becoming a mauve gray in age. The (2) photos I found of Psathyrella carbonicola shared some similarities with these images but the stipes seemed entirely different so, for now, I’m going to call this an unknown.3/7/07—See also Observation 2694 (you can first do a location search for Howarth and find it more easily that way). Both P. carbonicola and P. pennata are both found in burn sites, which neither of these were. I don’t know if fungi found in burn sites can be found elsewhere, so have “downgraded” this identification, for now.

6 months ago I would not have called these P. candolleana, but then I saw some in February this year that looked like these… I didn’t suspect P. candolleana when Douglas found them, but he did the microscopy and it was a clear match for P. candolleana:

…because I’ve never found these anywhere near any kind of burn. I didn’t call it P. candolleana because they don’t look like any that I’ve seen and don’t fit the description in the keys developed by Ian Gibson of South Vancouver Island Mycological Society which was the only resource I could find to try to identify Psathyrella

The photos are a good fit for Psathyrella carbonicola.

Agrocybe not squamulose

A. praecox has a smooth, kinda placticy feeling cap. These are nice and shaggy, or squamulose. The way they break radially in age, kinda points to an Inocybe, but not sure. Pholiotas are also squamulose, but usually with dark brown shaggy scales, instead of these bright white ones.

Cute little guys though… nice photos.
