Plicaria carbonaria is a species of fungus in the family Pezizaceae, order Pezizales, class Ascomycota. It is a small to medium-sized, cup-shaped fungus that grows on burnt soil, charcoal, or ash. In East and Central Texas, Plicaria carbonaria has been found in areas with rich soil and abundant organic matter, often near burned areas or old fire scars. The fungus typically fruits in the spring and summer months, producing ascospores that are brown to dark brown in color. It is relatively common in the region, particularly in areas with post oak, blackjack oak, and other hardwood species.

Spores of cup fungus Plicaria carbonaria from burned soil, collected a day before in Lake Bryan Park. Texas, May 10, 2024Plicaria carbonaria was observed growing on burned soil and campfire sites in East and Central Texas. The fungus formed small, brown cups with round spores that had coarse, blunt, wart-like spines. Observations were made at two locations: Sam Houston National Forest north of Montgomery, where the fungus was found on a bonfire place on a sandy bottom of a dried creek, and Lake Bryan Park in Bryan, Texas, where it grew on burned soil under juniper trees. The fungus was often found alongside other species, such as Anthracobia tristis. Microscopic examination revealed the presence of asci with spores, which were observed at various magnifications. The spores were also examined using different staining techniques, including Congo red and lugol. Overall, Plicaria carbonaria appears to thrive in areas with burned soil and campfire residue.
