Genus Truncospora Pilát ex Pilát

[split out of Perenniporia]

This genus has both temperate and tropical species. Spirin et al. (2015) examined the Truncospora ohiensis group worldwide and revealed seven species, listed below; five of these are in North America. Zhao et al. (2016) described a new species from Wisconsin: Truncospora wisconsinensis that has white annual brackets, larger pores (3-5 per mm), dimitic hyphal system, and spores smaller than T. ohiensis. This new segregate species should be looked for in the Midwest.

  1. Truncospora arizonica, in Arizona on oak.
  2. Truncospora atlantica, in Macaronesia (Canary Islands, Madeira), Iberian Peninsula.
  3. Truncospora floridana, in Florida.
  4. Truncospora mexicana, in Mexico, Texas, Cuba.
  5. Truncospora ochroleuca group (Australia, Asia, Africa, Central America) is likely multiple species and needs study.
  6. Truncospora ohiensis, widespread in the East; a very small conk on hardwood logs.
  7. Truncospora ornata, in Russian Far East and North-East China.
  8. Truncospora tropicalis, in the Florida Keys, Hispaniola, Puerto Rico.
  9. Truncospora wisconsinensis, in Wisconsin.

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 1941 publication of Truncospora was invalid because a type species was not designated: Pilát. 1941. Atlas des Champignons de l'Europe, III: Polyporaceae I: 365.
