Substrate:
The inner surface of the bark from a large log of downed dead Populus (I peeled the loose bark off the dead downed wet Populus log).
Description:
Fruiting bodies are sessile sporangia, numerous & crowded but not adherent, round, pulvinate and slightly flattened, mostly 0.5–0.7 mm in diameter with a distinct purplish brown persistent upper peridial cover which separates from the lower peridium at a yellowish circumscissile line to expose the inner tan to tan-yellow spores. The basal portion of the peridium left as an empty blackish cup when the purplish brown cover and spores have been shed. Most of the sporangia with a grayish hoary residue covering the purplish brown upper peridium. Capillitial threads very sparse. Spores globose, finely but distinctly verruculose, yellowish in transmitted-light slide mounts (more tan to yellow tan by reflected light in dissecting scope views), mostly 12 μm in diameter.
Notes:
Perichaena corticalis is the most commonly-collected species in the genus. It has 851 collection records on the Mycoportal website. Index Fungorum (March 2023) records 99 species & varieties in the genus Perichaena, with some of these considered synonyms of species in other trichiaceous genera or synonyms of P. corticalis.
