Genus Truncospora Pilát ex Pilát

Acta Musei Nationalis Pragae 9B (2): 108 (1953)

Type: Polyporus ochroleucus Berk., London Journal of Botany 4: 53 (1845)

This genus has both temperate and tropical species. Spirin et al. (2015) examined the Truncospora ohiensis group worldwide and revealed seven species. Five of these are in North America: Truncospora ohiensis widespread in the East; T. arizonica in Arizona on oak; T. floridana in Florida; T. mexicana in Mexico, Texas, Cuba; and T. tropicalis in the Florida Keys, Hispaniola, Puerto Rico. The other two species are T. atlantica in Macaronesia (Canary Islands, Madeira), Iberian Peninsula; and T. ornata in Russian Far East and North-East China. The Truncospora ochroleuca group (Australia, Asia, Africa, Central America) is likely multiple species and needs study.

  1. Perenniporia ohiensis is a very small conk on hardwood logs.
Truncospora was treated as a synonym of Perenniporia but is now recognized again. The genus Perenniporia is in the process of being split up into multiple genera. The original publication of Truncospora was invalid because a type species was not designated: Pilát. 1941. Atlas des Champignons de l'Europe, III: Polyporaceae I: 365.
