Growing in Mosses.

Cap - Largest is 1.7 cm diameter. Cap shape is ovate. Cap is smooth, striations at edge caused by gills. Even smallest does not show Partial Veil. Cap lighter at top.

Stipe - Much longer than cap is wide ( variable ), fibrous, thin, uniform width. I could see a small bit of mycelium at the base.

Gills - Brown like cap. Adnate. Subdistant to Distant, deep. Distant complete gill with several shorter partial gills between.

Spore Print - Looked black but might be very dark brown-purple.

Staining - no change of color with cut or bruised.

Odor - mild mushroom

Spore Sizes - Description
Ellipsoid, Smooth, Thick-walled, Apical pore,

[20/1/1] L (-5.5) 6.1 – 7.1 (-) μm x W (-3.7) 4.2 – 4.8 (-4.9) μm, (L = 6.6 μm, W = 4.4 μm), Q (-1.35) 1.42 – 1.58 (-1.60), Q = 1.50 Ellipsoid

Microscopic features - It was difficult to see details as everything was covered by dense layers of spores. I could only tell that the paellas was not cellular and had no gelatinized material.

I could see filiform Cheilocystidida a the gill tip. See image.

It appeared the basidia held 4 spores.

Genus - Formerly Genus Psilocybe but non-staining species moved to Genus Deconica
