Observation 215521: Entoloma subgenus Leptonia (Fr. : Fr.) Noordel.
When: 2015-09-14
(21.4497° -158.0282° 212m)
No herbarium specimen

Notes: Several small black mushrooms, including one with partially white stalk. One individual was collected and measured, as follows:
Cap: black, bell-shaped with central dimple, leathery texture–or shriveled–12 mm diameter. Stem: equal but tapering, 40 mm long, 3 mm diameter at the base tapering to 2 mm at the cap. Gills: brown, attached, close.

Observed in a suburban neighborhood on a mesic, tropical, insular lowland plateau, in my backyard, emerging from leaf litter. In appearance they are similar to some inky caps, however they seemed to wilt after about a day, rather than deliquesce.

After about two weeks, three more mushrooms were observed to have emerged at the original observation site. Once again no deliquescing was observed. Four additional images have been uploaded. One individual seemed to have a “mature” cap, and was collected. Data for this individual are:

Cap: flat to slightly sunken, non-circular, 27 × 23 mm, dark gray, ribbed, margin uneven. Stem: bent, base white, upper length light gray, 55 mm long, including bend, club-shaped (tapering), flat (non circular cross section) 3 mm x 1 mm. Gills: attached, descending, close, light gray with maybe a hint of light pink.
