Ophiotheca pedata Garcia-Cunch., J. C. Zamora & Lado

Ophiotheca aff. pedata (Lister & G. Lister) García-Cunch., J.C. Zamora & Lado [0, 2] Fig. 32 Loc 11: On Y sp. debris, JRM126, 12 May 2009, (mc, pH = 7.5), JRM198, 13 September 2008, (mc, pH = 7.6). This specimen is characterized by the globose, sub-stipitate sporocarps (Fig. 30), 0.9–1.2 mm diam., bright yellow, with dehiscence by polygonal plates. The capillitium scanty, with irregular tubular threads, and short spiny at the surface. Spores are globose and verrucose, 10.9–12.7 diam. Mapimí specimens appear to be closer to O. pedata (≡ Perichaena pedata) by the kind of dehiscence, capillitium ornamentation and reminiscent stipes, yet the spore size does not coincide with this species (9–10 diam.) (Mitchell 2001). If confirmed, this collection would be the second record of O. pedata for Mexico.
