Summary:
Features include a minute (less than 0.1cm), light yellowish to orange fruiting body with roughened spore-bearing upper surface and setose outer surface, growth on dung, and microscopic characters. PezWeb preliminary checklist of North American Pezizales (which emphasizes western species) includes this species. Bezerra(1) give Lasiobolus papillatus (Pers. ex Fr.) Sacc. among the synonyms for Lasiobolus ciliatus (Schmidt ex Pers.) Boud., but the online Species Fungorum, accessed February 3, 2017, listed Lasiobolus ciliatus (J.C. Schmidt) Boud. as a synonym of Lasiobolus papillatus (Pers.) Sacc. and MycoBank, accessed the same date, listed Lasiobolus ciliatus (J.C. Schmidt) Boud. as an illegitimate name. The description here is derived from Bezerra(1) for Lasiobolus papillatus (Pers. ex Fr.) Sacc.

Microscopic:
spores (17)19-25 x (9)12-14(15) microns, elliptic, rounded at both ends, colorless, each with a prominent deBary bubble, smooth walled, uniseriate or biseriate; asci 8-spored, (112)180-270 x 15-30 microns, clavate-cylindric, rounded or truncate at top, narrowed in lower part to stem; paraphyses filiform [thread-like], colorless, septate, branched, 2-2.5 microns wide in lower part, slightly inflated to 2.5-3.5 microns at top; setae 200-600 microns long and (12)20-42 microns wide at widest part, non-septate, pointed, distinctly ventricose at base
