Abstract
During our studies of freshwater fungi from Thailand, a new species
Minimelanolocus nonramosus
and a new collection of
Thysanorea papuana
were identified using morphological characters and phylogenetic analyses based on LSU, SSU, and ITS genes. After re-examination of herbarium material,
Thysanorea aquatica
is synonymized with
Th. papuana
. The description of the new species is provided with notes. This study increases our understanding of the freshwater hyphomycetes in Eurotiomycetes.
