Common name: Peg Lichen.
Cladonia subcariosa is a species of fruticose lichen that forms dense, mat-like cushions. It has pale green to yellow-green primary thalli with numerous, slender, greyish to brownish podetia that are typically 1-3 cm tall and bear red-brown apothecia. In East and Central Texas, Cladonia subcariosa is found on acidic soils, sandy areas, and open woodlands, often in association with other lichens and mosses. It thrives in full sun to partial shade and is commonly encountered in the region's pine-oak woodlands and sandy prairies.

Peg lichen Cladonia subcariosa with brown spore organs on sandy soil of a field on Kings Hill in Little Thicket Nature Sanctuary. Cleveland, Texas, March 25, 2023San Jacinto County, Texas, United StatesObservations of Cladonia subcariosa in East and Central Texas reveal its presence on sandy soils. On Kings Hill in Little Thicket Nature Sanctuary, Cleveland, Texas, the lichen was found growing on sandy soil in a field on March 25, 2023. The species was identified as either Cladonia subcariosa or possibly C. polycarpia. Notably, some specimens of Cladonia subcariosa displayed brown spore organs, indicating reproductive activity. These findings suggest that Cladonia subcariosa thrives in open, sandy areas, and its growth is likely influenced by the local soil conditions and climate. The presence of brown spore organs also implies that the species is actively reproducing in these environments, contributing to its persistence and spread in East and Central Texas. Further observations may be necessary to fully understand the distribution and ecology of Cladonia subcariosa in this region.
