Truncospora
Truncospora is a genus of fungi in the family Polyporaceae.
Taxonomy
The genus was originally proposed by Czech mycologist Albert Pilát in 1941, but this publication is invalid because a type species was not designated, contrary to the rules of botanical nomenclature. He published the genus validly in 1953 with two species: Truncospora oboensis, and the type, T. ochroleuca. Leif Ryvarden placed the genus in synonymy with Perenniporia in 1972, but molecular studies have shown that Truncospora is distinct genetically, and comprises part of the "core polyporoid clade", a grouping of fungi roughly equivalent to the family Polyporaceae.The generic name Truncospora is derived from the Latin trunco and the Ancient Greek σπορά.
Description
Truncospora is characterized by relatively small, cap-forming fruit bodies that generally measure about long, wide, and thick. The skeletal hyphae range from non-dextrinoid to dextrinoid, and the spores are truncate and strongly dextrinoid.Species
