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 and Range

SIMILAR SPECIES
Mitrula elegans has less regularly shaped, yellow to golden orange head, and different spores, (Trudell).
Habitat
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)
