Perichaena corticalis (Batsch) Rost., Mon. 293. 1875.

Lycoperdon corticale Batsch, Elench. Fung.155. 1783.

 Description: Fructification sporangiate to plasmodiocarpous, scattered or gregarious, dark redish brown to blackish, sessile, subglobose, pulvinate, or annular, 0.15-0.5 mm in diameter. Peridium double, outer layer thick, opaque, granular, uaually marked with distinct dehiscent llines in a reticulate pattern, inner layer membranous, translucent, closely adherent to the outer layer. Capillitium not abundant, appearing arising from the inner peridium, the threads irregular, slender and scarcely branched, 2-3 μm in diameter, spinulate, with scattered swellings (6-10 μm in diameter). Spores golden yellow in mass, pale yellow by transmitted light, globose, subglobose, minutely warted, 10-13 (-14) μm in diameter.

 Note: The yellow line of the fructification is the inner layer of peridum which is translucent. The reticulate ridges on the fructification and the slender, spinulate capillitial threads resemble the characteristics found in Perichana chrysperma. P. corticalis differs from P. chrysosperma in having larger spores and capillitium with shorter spines. The capillitial threads when viewed under SEM are densely pitted, with long spines.
