Synonyms: Melanotheca anomala, Mycoporum anomalum, Trypethelium anomalum.
Common name: pox lichen.
Pyrenula anomala is a crustose lichen that grows on trees, particularly oak and cedar, in shaded areas. In East and Central Texas, it forms black, irregularly shaped patches with a rough, wart-like surface, and produces perithecia that are partially immersed in the thallus. The species is relatively rare in the region, but can be found on mature trees in humid, wooded areas, such as those along streams and rivers.

Pox (rash) lichen Pyrenula anomala on a deciduous tree in Big Creek Scenic Area of Sam Houston National Forest. Shepherd, Texas, February 1, 2019Lone Star Hiking Trail, Coldspring, TX 77331, USAObservations of Pyrenula anomala in East and Central Texas reveal its presence on various substrates. On a tree bark in the Big Creek Scenic Area of Sam Houston National Forest, the lichen was spotted in Shepherd, Texas, on February 1, 2019. The species was also found on a deciduous tree in the same area, displaying a characteristic "pox" or "rash" appearance. These sightings suggest that Pyrenula anomala can thrive on different types of trees in the region. The lichen's ability to colonize both coniferous and deciduous tree barks indicates its adaptability to various environments in East and Central Texas. The observed specimens exhibited typical features of the species, with a crustose thallus and perithecia that give it a distinctive appearance. These findings contribute to our understanding of the distribution and ecology of Pyrenula anomala in the region.
