Mountain tips as reservoirs for new rock-fungal entities: Saxomyces gen. nov. and four new species from the Alps
As part of a worldwide sampling nine black fungi were isolated from rocks collected in four distinct sites of the Alps at high altitudes. Based on a nucSSU, nucLSU and mtSSU multi-locus phylogeny, seven of them were found to cluster into a distinct and well-supported clade in a basal position within...

As part of a worldwide sampling nine black fungi were isolated from rocks collected in four distinct sites of the Alps at high altitudes.

As in other rock fungi these new groups of isolates were characterized by a meristematic growth and a scarcely differentiated morphology with highly melanized and thick-walled toruloid hyphae. Nonetheless, few peculiar characters were also observed as convoluted hyphal tips and the production of spherical propagules. The new genus and species Saxomyces alpinus and S. penninicus, are here described based on morphological and molecular data, in a yet to be defined order of the Dothideomycetes.
