Thaxteriella pezizula is a fungal plant pathogen, known for infecting sweetgums (Liquidambar sp). The fungus is saprobic on woody substrates. It has a mycelium (root-like structure) that forms a dense velvety subiculum (support) on the surface of the bark, which consists of black hyphae.
The fungus was published by (Berk. & M.A. Curtis) Petr. in Sydowia 7(1-4): 110 in 1953.
It is found in North America, Central America, South America, Europe, New Zealand and Australia.
