Summary:
Features include 1) thin, flat growth on dung in association with Saccobolus violascens, 2) narrow-obovate spores, 3) details of basidial development, 4) hyphae that mostly 1.5-2.5 microns in diameter, all septa with clamp connections in the hymenial region, some hyphae moniliform or tortuous, paraphysis-like and extending into the hymenium.

Microscopic:
SPORES 10-11 x 4-6 microns, ovoid; PROBASIDIA cylindric-clavate, giving rise at the tips to cylindric epibasidia 36-42 x 5-6 microns that become transversely 3-septate, (Martin), SPORES (6.5) 9-10 x 4-5 microns, narrow-obovate, flattened adaxially, with a very small apiculus, germinating by repetition; BASIDIA when mature mostly 4-septate, the sporogenous part 39-54 x (3.5)4-5 microns, the total length reaching 120 microns although most less than 100 microns; epibasidia lacking or up to 25 x 2.5-3 microns; probasidia "at first cylindric to narrow clavate or pyriform, thin walled, developing a cylindric sporogenous portion apically, often in compact clusters formed through proliferation at the basal clamp, 6-9 microns in diameter and mostly 15-25 microns in length, a few exceeding 50 microns"; hyphae mostly 1.5-2.5 microns in diameter, all septa with clamp connections in the hymenial region, "some hyphae moniliform or tortuous, paraphysis-like and extending into hymenium", (Bandoni)

Notes:
It has been found in in BC and MB, (Ginns), and in Germany, (Martin).
