Observation 216853: Coprinopsis sect. Lanatuli (J. Lange) D.J. Schafer ined.
When: 2015-09-22
Herbarium specimen reported

Notes: Habitat: small garden plot – sandy with a bit of mulch has cactus and grasses. Growing in dirt, not on mulch. Gets wet from sprinklers.

Cap: 2-4 cm mature diameter. Pleated with small scales at top. Beige color. Fragile, breaks apart easily. Thin context.

Gills: Beige in youngest, quickly becomeing dark from spore. Starting to dissolve but I don’t think this one dissolves completely. The most mature showed blackened tattered edges of the cap.

Stipe: length about 1.25 x the width of the cap. White, with enlargement at base where the stalk is rooted into the ground. The enlargement was on every stalk to some degree and almost appeared as a ring. On the youngest caps I could see lines at the top of the stalk where the gills had originally been stuck. I saw no evidence of a ring on any. I did see light sprinkling of tiny white granules along the stalk.

Spore Print : Very dark, black

Coprinopsis

The gills in Coprinopsis don’t fully dissolve in these species with very thin caps. (for example Coprinopsis lagopus).

Coprinopsis or Coprinellus

I debated on which. While Coprinopsis is described as having veil remnants on the cap, Coprinellus also has a veil.

Coprinopsis is described as having gills that fully dissolve while Coprinopsis has gills that do not fully desolve.

This mushroom’s gills do not fully dissolve which seems to leave out Coprinopsis and a candidate.
