Remarks (internal):Trechispora nivea is characterized by having a hydnoid hymenial surface, and by producing verrucose, broadly ellipsoid to sub-globose basidiospores measuring 3.5-4 x 2.5-3 pm. This species is similar to T..farinacea (Pers.: Fr.) Liberta, but differs in its hyphal morphology in the trama of aculei. Trechispora nivea produces aculei consisting of long-celled hyphae whereas T. farinacea has short-celled ones in aculei. According to Larsson (1995), T. nivea is widely distributed from tropical to cold temperate regions.

Basidiomata resupinate, loosely adnate. effused, thin excepting aculei. fragile; hymenial surface grayish white to "Buff", odontoid, pruinose under the lens (x 20): aculei 5-10 per mm2, conical, up to 1 mm in length; margin concolorous with the hymeninal surface, thinning out, indeterminate, sometimes fimbriate under the lens (x 20).
