New species of Jahnula (Jahnulales, Dothideomycetes) and new records of aquatic ascomycetes from estuarine beaches of the Brazilian Amazon

ABSTRACT

Estuaries are considered promising habitats for the presence of marine and freshwater fungal species because of their favourable environmental conditions. Janhula paraensis sp. nov. was found on decaying wood collected in the intertidal zone in fluvial beaches of Mosqueiro Island, Pará, Brazil. The new species differs from others in the genus by its morphology including dark brown ascospores, with thick and dark bands at septum when mature, a hyaline cap at both ends and the absence of a mucilaginous sheath. It was not possible to obtain molecular data for the new species. New records of Boerlagiomyces websteri, Corollospora pseudopulchella, Falciformispora lignatilis, and Savoryella lignicola for South America and Annulusmagnus triseptatus for Brazil are reported. Morphological descriptions and illustrations are presented for all species.
