Coprinellus saccharinus (Romag.) P. Roux, Guy Garcia & Dumas, 2006
CS80 Wied il-Luq (20/3/10)
Description: Small partially auto-digesting agarics, gregarious but occasionally solitary on soil with leaf litter.

Pileus: Ovoid to conical to convex flattening on maturity and auto-digesting (but not completely). Largest specimen 30mm wide. Maximum pileus height 16mm. Ochre-brown in colour becoming darker at the apex. Deeply sulcate, velar remnants on pileus flocculose. Setae or hairs absent.
Stipe: Cylindrical and straight, hollow centrally, white without colour change on cutting. Velar remnants present near the base. Diameter up to 3mm.
Gills: Free to adnexed, brownish changing to black and auto-digesting into a black liquid. Gill edge shows a layer of transparent cystidia.
Spore Print: Blackish liquid.

Microscopy:
Basidia:
4-spored (8-9µm width; 16-21µm height).
Pileipellis: Cellular with a lower layer of interwoven filamentous hyphae.
Pileocystidia: Absent
Cheilocystidia: Abundant, large and cylindric in shape (42-47µm width; 98-118µm height).
Pleurocystidia: Present similar to cheilocystidia
(44-45µm width; 105-121µm height).
Caulocystidia: Absent.
Spores: Ellipsoid to sub-mitriform, smooth with germ pore (1.4-2µm) and thick wall. L=7.3-10.5µm; W=5.3-7.4µm; Q=1.27-1.54, Qm:1.40
