It is found in the US, Canada, Europe, and New Zealand. A collection from BC is deposited at the University of British Columbia.
Upper surface:
0.3-0.7cm wide, 0.6-1cm high, "umbilicate, convex-discoid, sometimes convolute", cinnamon-brown
Stem:
chestnut-brown; growing from sclerotium that is black and 0.009-0.03cm in diameter
Microscopic:
spores 10-16 x 5.6-9.5 microns, elliptic, colorless, usually with one oil droplet, uniseriate; asci 8-spored, reaching 190-235 x 8-10 microns, cylindric to cylindric-clavate; paraphyses abundant, 2.8-3.2 microns in diameter at tip, filiform, slightly clavate; microconidia 1.2-1.8 microns wide, apparently functioning as spermatia
