Trechispora is a genus of fungi in the family Hydnodontaceae. Basidiocarps (fruit bodies) are variously corticioid (effused, patch-forming) or clavarioid (branched and coral-like) with spore-bearing surfaces that are variously smooth to hydnoid or poroid. The genus occurs worldwide, though individual species may be localized. Around 50 species have been described to date.
