0.1-1.1cm high, 0.01-0.03cm wide, acicular [needle-like], attenuate to a filiform apex (narrowing to a thread-like tip), rarely nearly cylindric with obtuse, abrupt, or mucronate tip, without stem or with indistinct stem 0.01-0.05cm long, unbranched, occasionally with an adventitious branch from the stem, more or less gregarious or subfasciculate (almost bundled), superficial on a slight mycelial patch, the base often slightly dilated and subvillous (slightly downy); white, (Corner(2)), 0.2-1cm tall, "slender, hair-like, circular in cross-section", (Buczacki)
Stem:
without stem or with indistinct stem 0.01-0.05cm long, (Corner(2))
Odor:
strong, unpleasant, chemical, (Buczacki)
Taste:
indistinct (Buczacki)
Microscopic:
spores 9-16 x 4-7 microns, elliptic-oblong, blunt or subacute, smooth, white, thin-walled, cloudy vacuolate, no droplets; basidia 2-spored, 20-30 x 7-9 microns, clavate, sterigmata 4-5 microns long; cystidia frequent, varying from sterile basidia, 25-40 x 5-8 microns, "narrowed at the apex, to subconical or subventricose cells with subacute apex, thin-walled, colourless, smooth, rarely with a small subglobose stalked appendage with an abortive spore"; hymenium "continuous from the base, sometimes lacking from the extreme base or decomposing from below upward and the stem secondarily denudate, the sterile apex sometimes becoming fertile on cessation of growth", hymenium "not thickening: subhymenium very slightly developed, short-celled, or the basidia arising directly from the longitudinal hyphae"; caulocystidia "none or as scattered, rudimentary basidia or cystidia on the short sterile stem, -20 x 6 microns, thin-walled, obtuse"; hyphae dimitic: skeletal hyphae 2.5-3.5(4) microns wide, "the walls 0.5-1 microns thick, aseptate, rarely with a short branch, smooth, traversing the length of the fruit-body, abundant: generative hyphae 1.5-3 microns wide, thin-walled, clamped", (Corner(2)), spores 5.5-7.5 x 3-4 microns, elongated elliptic, smooth; cystidia club-shaped; basidia 2-spored; hyphal system dimitic, (Buczacki)

Habitat / Range

"on dead stems and leaves of Juncus, Carex, Cladium, Typha, Eupatorium, grasses &c., in swampy places", (Corner(2)), single or in small +/- trooping groups, densely crowded, on organic debris, old leaves, litter in hardwood woodland and other sites, especially wet habitats, perhaps all year, (Buczacki)
