Tremella parmeliarum is a jelly fungus that grows as a parasite on lichens, typically forming gelatinous, brain-like or convoluted structures. In East and Central Texas, it has been found on various tree species, including oak and cedar, often in shaded, humid areas with abundant lichen growth. The fungus is relatively small, usually 1-5 cm in diameter, and has a pale yellow to orange-yellow color. It fruits throughout the year, but is most commonly seen during the spring and fall months when moisture is more abundant.

Brown and greenish galls of lichenicolous fungus Tremella parmeliarum on powdered ruffle lichen (Parmotrema hypotropum) on a bush of upland swamp-privet in semi-open area at Lake Somerville Trailway near Birch Creek Unit of Somerville Lake State Park. Texas, December 20, 2021Lakeview Drive, Burleson County, Texas, United StatesObservations of Tremella parmeliarum in East and Central Texas reveal its parasitic relationship with powdered ruffle lichen (Parmotrema hypotropum). The fungus was found on twigs and bushes of upland swamp-privet at Lake Somerville Trailway near Birch Creek Unit of Somerville Lake State Park. On December 20, 2021, the fungus formed galls on the lichen, which appeared as brown and greenish growths. The galls were observed in semi-open areas, indicating the fungus's ability to thrive in various environments. The consistent presence of Tremella parmeliarum with Parmotrema hypotropum suggests a specific host-fungus relationship. The observations highlight the diversity of fungal species in East and Central Texas and their interactions with other organisms in the ecosystem. The fungus's appearance on multiple occasions at the same location also suggests its prevalence in the region.
