KEYWORDS
ABSTRACT
The Neotropics, particularly mountain cloud forests, are characterized by a high diversity of microfungi that inhabit lichens. However, based on our field studies, many of these microfungi remain undescribed, and their phylogenetic relationships are poorly
understood. This study focuses on Bolivian lichenicolous Trichonectria inhabiting the genus
Usnea (Parmeliaceae), a common lichen host in the tropical Andean forests. Here, we present
14 species of which eight are described as new to science: Trichonectria abortispora sp.
nov., T. biglobospora sp. nov., T. boliviana sp. nov., T. citrispora sp. nov., T. cylindrospora
sp. nov., T. gigaspora sp. nov., T. microsporusneae sp. nov. and T. toensbergiana sp. nov.
The five-locus phylogenetic analyses show that the anamorphic genus Cylindromonium
and the teleomorphic genus Trichonectria cluster together in a well-supported clade within
the order Hypocreales, but we have not yet reached a taxonomic conclusion. Phylogenetic
placements of five lichenicolous species of the genus Trichonectria are reported here for
the first time, including T. vinosa comb. nov.
