New species and new records of trichomycetes from Italy.

We present the results obtained from a short survey in central Italy to broaden the poorly known diversity of trichomycetous gut symbionts, members of the Kickxellomycotina, in this country. Among the reported fungi, two new species of Harpellales are described: Harpellomyces aprutinus and Orphella italica, as well as 14 other species that are new for Italy. Among these, the remarkable and rare species Gauthieromyces microsporus is included, previously known only from the type locality in France. One species of Asellariales, Asellaria gramenei, also is reported. Taxonomic and biogeographic implications of these records are discussed.
