Coprinellus angulatus
(Peck) Redhead, Vilgalys & Moncalvo
,
Taxon 50(1): 232 (2001)
(
Figure 2
, a–e)
Closed pileus
initially ellipsoid, 13–18 ×
9–13 mm
, ochraceous brown to gray-brown, becoming lighter towards the margin, naked, with several setose pileocystidia, hardly observable in stereomicroscopy.
Expanded pileus
campanulate,
25–27 mm
in diameter, dark gray to whitish.
Veil
absent.
Lamellae
free, rarely adnexed, initially whitish, finally dark gray to black with the maturation of basidia and basidiospores.
Stipe
central, cylindrical, hollow, pubescent, straight or crooked, whitish,
25–50 mm
long,
1.5–2 mm
in diameter.
Ring
absent.
Volva
absent.
Pileocystidia
abundant, setose, 75–110 μm, lageniform, decreasing considerably in diameter towards the apex, about 10–15 μm in diameter at the proximal end, tapering to 1–2 μm near the distal end, hyaline, smooth, thin-walled. Cheilocystidia not observed. Pleurocystidia not observed.
Basidia
4-spored, club-shaped, surrounded by hyphidial elements.
Basidiospores
mitriform in frontal view, cylindrical to ellipsoid in side view, flat, dark reddish brown, 7.2–8.5 × 6–7.5 μm, thick-walled, with a central germ pore.

Notes:
—
Coprinellus angulatus
, a rare species on herbivore dung, has small basidiomata forming directly on incubated dung, with a thinner stipe than the specimens described from soil or plant material. It can be easily distinguished by the combination of the following characters: naked pileus, with setose pileocystida exceeding
100 mm
in length and mitriform basidiospores in frontal view.
