Taxonomy

The genus was originally proposed by Czech mycologist Albert Pilát in 1941,[1] but this publication is invalid because a type species was not designated, contrary to the rules of botanical nomenclature.[2] He published the genus validly in 1953 with two species: Truncospora oboensis, and the type, T. ochroleuca.[3] Leif Ryvarden placed the genus in synonymy with Perenniporia in 1972,[4] 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.[5][6]

The generic name Truncospora is derived from the Latin trunco ("I cut off") and the Ancient Greek σπορά ("spore").[7]

Description

Truncospora is characterized by relatively small, cap-forming fruit bodies that generally measure about 1.5–3 cm (0.6–1.2 in) long, 2.5–3.5 cm (1.0–1.4 in) wide, and 1–4 cm (0.4–1.6 in) thick. The skeletal hyphae range from non-dextrinoid to dextrinoid, and the spores are truncate and strongly dextrinoid.[3][8]
