Fruiting body a stipitate ascocarp; apothecia 3.0-6.0 (10.0) mm broad, at first obtuse-conic to turbinate, in age convex to nearly plane; margin lacking hairs, plane to decurved at maturity; hymenium glabrous, moist, cream to dull-brown, slightly darker at the center; outer surface glabrous, colored like the hymenium; stipe 1.0-2.0 cm long, 1.0 mm thick, enlarged towards the apex, watery-white, becoming dark-brown to blackish towards the base; surface slightly tomentose (use hand lens); odor and taste not distinctive.
Spores 9.5-17.5 x 3.5-4.5 µm, oblong-cylindrical to subfusiform, smooth; spore deposit not seen.
Solitary to gregarious on rotting stems of grasses and herbs in boggy montane meadows; fruiting in the spring shortly after snow melt; common, but rarely collected because of its size.
Edibility unknown; insignificant.
is a small stipitate cup fungus sometimes confused with
when found fruiting on the remains of Corn Lily (
spp.) It differs, however, in its typically smaller size, convex to nearly plane, not cupulate, apothecium, and the lack of a sclerotium at the base of the stipe. Other stipitate Ascomycetes found on plant debris in the spring include species of
. These generally differ either in color or size, often less than 2 mm.
