Observation 188792: Psathyrella (Fr.) Quél.

When: 2014-11-13

Collection location: Overton City Park, Overton, Smith Co., Texas, USA [Click for map]

Who: L G Price (LG_Price)

No specimen available

The mature cap was partially desiccated. The small button was fully inside the decaying hardwood branch. I broke open the branch and saw it inside. The button has an intact veil. When I pulled the veil aside I could see that the the gills were originally white but already turning darker probably due to spore. The mycelium is white.

The button shows gills that are joined to the stalk, adcurrent, but not running down the stalk.
Some partial veil material can still be seen around the cap edge of the mature specimen. The dark gills of the mature specimen are probably dark due to spore. The gill spacing is close with some short gills attached to the outer edge of the cap.

The mature stipe is fibrous/fleshy but not brittle and holds some moisture.
The surface of the cap appears to have been smooth and dry. The pileus is fleshy and moderate brown.

The stipe shape is “compressed”. The immature stipe is white and the mature stipe is tan with white fibers scattered over the surface and stretched longitudinally.

The spore print is dark brown as best I can tell, it’s not a heavy print.
