058AA1EC9CF48B4E918A292F7A8187D7.taxon	description	Description. Basidiomata (Fig. 3) small with very short stipe, sometimes appearing resupinate or pseudostipitate (but not so), arising directly from substrate twig usually in fissures in thin bark or as side branches of extensive, black, interwoven rhizomorphs which often occur without associated basidiomata. Pileus 2 - 6 (- 9) mm broad, at first convex to conchate, usually becoming plano-convex or applanate by maturity, often folding closed like a clam-shell upon drying, matt, often strongly sulcate-striate almost to centre, irregularly corrugate or tuberculate, very thin but pliable; disc " burnt umber " (7 E 7) to " wood brown " (7 C 4); limb near " pinkish-cinnamon " (7 B 5), " avellaneous " (7 B 3), " wood brown " (7 C 4), " fawn colour, " sometimes brown (7 E 5 - 7) to dark brown (7 F 5) to light brown (6 D-E 5 - 6) or brownish-orange (6 C 4) overall or with pale striations; margin even when young, wavy in age, not striate, sometimes pale to " tilleul buff " (7 B 2); pileus flesh thin, tough, pliable. Lamellae adnate, distant to very distant, shallow, fold-like to sublamelloid, thickish, occasionally weakly anastomosing, " tilleul buff " (7 B 2), " pale pinkish cinnamon " (6 A 2), pale brown (7 D 4), " avellaneous " (7 B 3), " vinaceous cinnamon " (7 B 4), usually becoming brownish, " sayal brown " (6 C 5) upon drying and storage; short lamellulae common. Stipe 0.5 - 6 x 0.5 - 1.5 mm, more or less terete, usually equal, central, strongly ageotropic (more or less straight when occurring on upper surface of substrate, strongly curved when occurring on vertical surface, almost pseudostipitate when occurring on lower surface of substrate), glabrous to unpolished, " fawn colour " (7 C 5), " army brown " (8 D 5) " fuscous " (6 E 4), " burnt umber " (7 E 7) to dark reddish-brown (8 F 6 - 8), black at base; insertion broad with minute, brown basal tuft, usually associated with small fissures in thin bark, rarely as a side branch of aerial rhizomorph; adventitious " stipes " occasionally hypertrophic and then clavate to fusiform. Rhizomorphs (Figs 3, 4 A, B) rarely absent, usually dominant, - 80 (- 450) x 0.3 - 0.6 mm, hair-like, matt to glabrous but not polished, black, tough, occasionally branched with spur branches, rarely anastomosed, but commonly braiding so as to appear thicker than individually, ranging from resupinate on woody substrate (black, adhering to substrate by minute fringe of brown hyphae) to producing ascending individuals (and then somewhat more slender than resupinate individuals), often colonising suspended leaves and twigs to form a substrate net, occasionally producing basidiomata on side branches, often 3 - 4 in a file. Taste negligible or weakly alliaceous (reportedly weakly krauty); odour negligible.	en	Petersen, Ronald H., Hughes, Karen W. (2019): Two additional species of Gymnopus (Euagarics, Basidiomycotina).
