Pileus primo ovatus, subglobosus vel ellipsoideus, usque ad 6 mm altus, ad 4 mm latus, toto pruinosus velo albo cinerascente, centro cremeo vel ochraceo, dein explanatus ad 10 mm latus, convexus vel applanatus margine deflexus. Lamellae, L = ca 18, l = 1-3, liberae, ex albo cinerascentes vel nigricantes. Stipes usque ad 50 x 0.5-1 mm, aequalis, albidus, juventute flocculosus, demum vitreus, versus basim incrassatus usque ad 1.5 mm, frequenter albo flocculosus. Odore nullo.

Basidia 15-36 x 7-9 µm, tetrasporigera. Pseudoparaphyses 3-5. Pleurocystidia vesiculosa, utriformia, ellipsoidea vel subcylindracea, interdum medio constricta. Cheilocystidia nulla. Velum e elementis globosis, usque ad 50 µm in diam., glabris vel granulosis constans. Fibulae presentes. Ad lignum putridum.
Holotypus: 'GERMANY: Mönchengladbach, Volksgarten (MTB 4804), 16 June 1984, H. Bender (L).

Closed pileus oval, subglobose to ellipsoid, up to 6 mm high and 4 mm wide, completely covered with powdery white veil, often cream to pale ochraceous at centre; expanded pileus up to 10 mm wide, convex or flat, finally with slightly deflexed margin; veil greying with age. Lamellae, L = c. 18, l = 1-3, free, white at first, then greyish to grey, finally black. Stipe up to 50 x 0.5-1 mm, equal, white, when young somewhat floccose, slightly hyaline; at base up to 1.5 mm wide, often with white velar flocks. Smell indistinctive.
Spores 10-11.5 x 6.5-7.0 x 5.8-6.5 µm, (according to Uljé: sp. 9.7-12.3 x 5.7-6.8 µm, Q = 1.45-1.90, av. Q = 1.70, av. L = 10.9, av. B = 6.4 µm), oval, ellipsoid or cylindrico-ellipsoid in frontal view, ellipsoid, sometimes slightly amygdaliform in face view, red-brown in water, with central germ pore. Basidia 15-36 x 7-9 µm, 4-spored, surrounded by 3-5 pseudoparaphyses. Pleurocystidia vesiculose, utriform, ellipsoid or subcylindric, some with median constriction. Veil made up of colourless to slightly yellowish, smooth to granular, up to 50 µm wide, globose elements. Clamp-connections present.
Habitat & distribution. Solitary or in small groups; on branches and other pieces of wood. Known only from type locality.

Collection examined. GERMANY: Mönchengladbach, Volksgarten (MTB 4804), 16 June 1984, H. Bender (holotype; L).

Coprinus nemoralis differs from other species having ellipsoid spores and pleurocystidia in its larger spores and cystidia and its growth on woody debris. C. pilosotomentosus has spores similar to those of C. nemoralis, but that species grows on grasses and the cystidia are much smaller. Up
