Cudoniella Sacc. 1889

A common discomycete on fallen wood with a Cudoniella-like macromorphology (convex hymenium). The micromorphology (see images under several of the cf. Cudoniella sp. specimens) and ITS based phylogeny show it is a different genus. Based on the ITS, it appears to belong amongst the Hyaloscyphaceae, but this may in part be due to incomplete taxon sampling and its long branch.

Cudoniella Sacc. 1889

The type species of Cudoniella, C. queletii, was accepted as a synonym of C. acicularis by Dennis (1964), following Boudier (1907). Specimens identified as C. acicularis, C. clavus, and C. indica have DNA sequences accessioned into GenBank. Based on these, C. acicularis and C. indica are both in Tricladiaceae, but phylogenetically distinct within the family (Fig. 2). Cudoniella clavus is a member of the core Helotiaceae sensu Johnston et al. (2019).

taxonomic status
Based on GenBank ITS accessions Cudoniella is polyphyletic. GenBank accessions appear to represent two species complexes, one referred to as Cudoniella clavus (Helotiaceae), a second as C. indica (Tricladiaceae). The type species C. queletii has no DNA sequence data available. [PRJ, Aug 2019]
