description: 11. Licea eremophila D. Wrigley, Lado & Estrada, Mycologia 102(5): 1186 (2010) Figs. 9A–L
Sporophores sporocarpic, dispersed or grouped. Sporocarps stipitate, occasionally subsessile, 0.1–0.35 mm high. Stalk cylindrical, dark brown to black, sometimes very short, 0.03–0.18 mm or absent. Sporotheca subglobose, angular where the peridial platelets meet 0.07–0.2 mm diam., angular, strong yellowish brown (Figs. 9 B – E). Peridium single, light brown by TL, with refuse deposits like dark spots sometimes on the outer surface, inner surface smooth, entirely made up of platelets; dehiscence by 10–15 polygonal platelets (Fig. 9 G). Spores free, strong yellow in mass, yellow by TL, often angular, (9–)10–12(–13) μm diam., roughened by TL (Figs. 9 H – I). Protoplasmodium colourless, becoming milky then yellow. By SEM the inner peridium is smooth except for the margins of the platelets that have a line of warts; the epispore densely warted, except along slightly raised bands (Figs. 9 K – L) with fewer or no warts (like a tennis ball).

Notes. This species is included in this study because its sporocarps dehisce into platelets and, it sometimes has very short stalks, and may appear sessile. The species was published after our study of the stalked Licea (Wrigley de Basanta & Lado 2005) and therefore was not included there. The strong yellow-brown, subglobose sporotheca, the peridium that fragments into defined polygonal platelets, and the angular spores, distinguish even the sessile sporocarps of this species from others in the group. The closest species to L. eremophila is L. verrucispora D. Wrigley & Lado, but in the latter species the peridium dehisces into irregular fragments, not defined platelets, it has globose spores, not angular ones, and a densely warted inner surface to the peridium.
