mysterious and spooky.
It's altogether ooky . . .
Camarops petersii looks like a bulging black eye, complete with eyelids, stuck to the side of a dead log. The eyelid is a veil that protects the young mushroom but soon ruptures to expose the spore-producing surface. The range of Camarops petersii in North America extends from eastern North America to at least Kansas and Cuba.
Ecology: Saprobic on the decorticated wood of fallen oaks (early records for the species also included wood of the now extinct American chestnut as a substrate); growing alone or in small clusters; late summer and fall; eastern North America to Kansas and Cuba.
Fruiting Body: 2-7 cm wide; up to about 2 cm high; sub-circular or broadly elliptical in outline; cushion-shaped, with a somewhat narrowed base; upper surface black and shiny, covered with pimple-like dots (and covered with black slime when the mushroom is producing spores); encased in a black, feltlike veil that soon ruptures and becomes a sheath around the sides of the fruiting body, with a ragged upper edge; interior tough and brownish, filled with black channels and pockets but not featuring concentric zones.
Chemical Reactions: Tissues from dried specimens brownish when crushed in KOH.
Microscopic Features: Asci 8-spored; deliquescing along with the paraphyses so that spores are exuded from the perithecia in a gelatinous black matrix (according to Nannfeldt , "[t]he ascus has lost its gun function"). Spores 6-8.5 x 3-4.5 µ smooth; broadly elliptical at one end and broadly fusiform at the other; with a tiny pore at the narrowed end; usually biguttulate in KOH or water mounts; purplish gray in KOH.
