Introduction: A unique ascomycete species that discolored the wood yellow was commonly found during taxonomic studies of fungi on submerged woody substrates in aquatic (lotic) settings in Ariège, at the foot of the Pyrénées. Additional sampling in additional areas revealed that it is common throughout northwest Spain and France. Ascomata, asci, and ascospore morphology all strongly indicate that this taxon is a member of the genus Phomatospora Saccharini. Barr (1994) offered a key to the North American species and made comments about the genus, which she limited to “herbaceous stems, monocot culms, and coriaceous leaves” and classified terrestrial. Since then, new taxa from marine habitats (Hyde 1988, 1992, 1993) and freshwater habitats (Scheuer 1988, Fallah & Shearer 1998, Raja & Shearer 2008) have been reported. However, no monographic investigation has been conducted on the genus Phoma-tospora. The novel taxon presented here adds a species that produces yellow pigments in the substrate, a characteristic not previously documented, to the general taxonomic group Phomatospora.
