Galzinia longibasidia Hallenb., Mycotaxon 11(2): 454, 1980.
MycoBank number: MB 112942, Facesoffungi number: FoF 02050
This is a little know species described by Hallenberg (1980) from Iran, and is characterized by its long basidia and relatively large, subcylindrical basidiospores. Here, we obtained ITS and LSU sequence data from the holotype material of G. longibasidia. Blast searches at NCBI shows the new sequences as close to Phanerochaete P. Karst. and Phlebia Fr. spp., with the highest similarity to uncultured and insufficently identified isolates. Galzinia is shown to be a polyphyletic genus, and G. longibasidia is nested within Polyporales but its closest relatives could be verified via thorough phylogenetic analyses of Polyporales, mainly the phlebioid clade.
