Fruiting body: 0.4-0.5cm high, cap 0.3-0.5cm wide, hemispheric-convex, margin obtuse; yellow, orange, or reddish-orange, rarely pallid, (Seaver), 0.3-2cm high, capped, stemmed, fleshy to subgelatinous; spore-bearing upper part 0.2-0.5cm wide, convex, thin, flesh-colored, pinkish buff or yellowish buff, with spore-bearing part on upper surface, margin frequently involute, (Mains), 1-1.5(2)cm tall, divided into head and stem, head up to 0.6cm wide, oval to lens-shaped; yolk-yellow to orange-yellow, (Breitenbach)
Stem: up to 1.5cm long, 0.1-0.2cm wide, white to bluish-gray, or brownish, rather darker in lower part; minutely squamulose [finely scaly], (Seaver), 0.1-0.2cm wide, round in cross-section; white; minutely tomentose, frequently matted and appearing smooth, (Mains), stem tapering downwards, pubescent with short, downy, blackish hairs, (Dennis), 0.2-0.4cm wide, cylindric; white, gray-whitish to brown-blackish; sometimes slightly downy and dark-scaled toward the base (blackish hairs), (Breitenbach)
Microscopic: spores up to 250 microns x 1 micron, slenderly filiform [thread-like], slightly narrowed toward each end, nearly as long as ascus, in a parallel fascicle in the ascus, multiseptate; asci 8-spored, up to 200-325 microns long and 5-6 microns wide, slender-cylindric, apex rounded, not blue with iodine; paraphyses thread-like, occasionally forked, the apices somewhat clavate-thickened and colored, (Seaver), ascospores very variable in length, (80)125-250(275) x 1 micron, filiform [thread-like], multiseptate; asci variable in length, 175-325 x 5-6 microns, narrowly clavate, gradually narrowing from near the apex; paraphyses straight, simple or branched, filiform in lower part, enlarged at apices, (Mains), spores 185-190 x 1.5 microns, filiform, colorless, smooth, multiply septate; asci 8-spored, 200-250 x 6-9 microns; paraphyses filiform, forked and slightly clavate toward tips, septate, (Breitenbach)
Habitat / Range
single, gregarious, or in clusters of 2 or 3 each, on wholly or partly submerged sticks etc., in brooks, mostly at higher altitudes, (Seaver), gregarious, cespitose [in tufts] or scattered, on decaying wood, leaves etc. in cold wet places, often in streams, (Mains), the ascospores, when mature, project and vibrate in the running water above the fertile area giving the fruiting body a white silky appearance, (Tylutki), gregarious on wood and remains of roots that are very wet or under water, in ditches among Sphagnum, or in small streams, commonly montane to alpine, (Breitenbach for Europe)
Similar Species
Mitrula elegans has less regularly shaped, yellow to golden orange head, and different spores, (Trudell).
