Observation 191683: Psathyrella conissans group
When: 2014-10-10
No herbarium specimen

Notes: -This specimen was associated with the soil, and it was found growing gregariously and scattered around the area.
-It had a faint/mild smell.
-Different sized samples were collected, but the sample that was believed to be the most mature was measured. The diameter was about 2.5 cm.
-The surface of the pileus was smooth, dry, and dull.
-The shape of the immature sample was broadly parabolic, but the more mature forms were more convex.
-The dark orange brown cap’s margins were smooth and not lined.
-The flesh was white.
-The pale orange stipe was centrally located. It was about 4.3 cm in length and 0.4 cm in width.
-When it was cut in half, the stipe was solid and equal shaped.
-The surface of the stipe was dull, dry, and smooth.
-The base was inserted.
-The light apricot colored gills were adnexed and even. It appeared to have two lamallae tiers.
-The spore print was white. Under 40x magnification, the spores looked like they were jelly bean shaped. Also, I was able to find cystidia that might be considered “fusiform”.
-Another thing to note was the white web-like material that covered the gills of the immature form.

The gill color and aspect suggest a Psathyrella in the Psathyrella conissans group. These have ruddy colored spores.
