Molecular and morphological data were
used to assess the taxonomic placement of an
undescribed lichenicolous basidiomycete teleomorph
collected in Luxembourg, Belgium and Germany.
The new species is ecologically and morphologically
similar to Marchandiobasidium aurantiacum, teleomorph
of the common bulbilliferous lichen pathogen
Marchandiomyces aurantiacus. However phylogenetic
analysis of nuclear and mitochondrial rDNA sequences
indicated a close relationship of the new species—
not to M. aurantiacum but to turf grass pathogens in
genera Laetisaria and Limonomyces, including the
generic type of Laetisaria. We are including the new
species in Laetisaria based on strong statistical
support for the clade containing these teleomorphs
and several Marchandiomyces anamorphs. The morphological
and ecological diversity of this clade
indicates a potentially significant evolutionary role
played by lichen-associated species in the Corticiales.
Key words: Corticium, Erythricium, Marchandiobasidium,
Marchandiomyces, mitosporic fungi, phylogeny,
rDNA.
