Camarops petersii (Berk. & M.A. Curtis) Nannf.

Svensk Botanisk Tidskrift 66 (4): 366 (1972)

dog's nose fungus (Hodge), black licorice drops (Volk), dead man's tongue (Shernoff).
Rounded cushion-shaped (pulvinate) to more raised with a tapered base (turbinate). When young covered with a brown veil that often leaves a collar around the margin. Surface shiny and with pimples. Stroma (flesh) with embedded perithicia (spore-producing chambers) with long necks. The spores are exuded out into a black slime.
Similar species:
This is the only species here with a veil and where the fruitbody is raised to this extent above the wood surface to becoming turbinate (shaped like a top). Camarops ohiensis is flatter cushion-shaped (pulvinate) and lacks the veil.
Saprobe on decorticated (barkless) hardwood logs, such as oak and elm. Eastern historic records are on American chestnut.
For Chicago Region found July to November; found once in May.
Eastern North America west to Kansas, Cuba and Asia (Japan, Russia, and the Far East). Possibly Brazil.
Chicago Region status:
Previously rare (3 observations for 1995, 1996; none for 1997–2002), now uncommon and regularly found once or twice per year. Found three times in 2015. There are no historic collections. The apparent first record for Illinois was made by Bruce W. Horn in 1982 at Starved Rock State Park, La Salle County (Horn 1984)
Original description by Berkeley and Curtis based on two specimens: one collected in Cuba by Ch. Wright, and one collected in Alabama by Judge Thomas M. Peters. Some mycologists accept the second specimen as the type because the species was named after Judge Peters.
The distinctive veil that covers young specimens led Shear to place the species in its own genus, Peridoxylon, but DNA phylogenetic evidence does not support this separation. Nannfeldt (1972) says As it has been much confused with the completely forgotten C. ohiensis, all records need confirmation. The name does seem forgotten; there are no records on MycoPortal.
Specimens examined:
We have 22 collections from 1995–2015.
