Thermophymatospora is a monotypic fungal genus in the family Polyporaceae containing the single species Thermophymatospora fibuligera, a basidiomycetous hyphomycete. Both the genus and species were described as new in 1986. The fungus was originally isolated from cultivated soil at a date palm plantation in Iraq. It has conidia that are brown, spherical, and relatively large (typically 20–24 μm). Its hyphae has clamp connections. The fungus has a growth temperature range of 17C48C, with an optimum between 35C40C.
The specific epithet fibuligera, from the Latin for "clamp-bearing", refers to the characteristic presence of clamp connections in the hyphae.
