Abstract
The new genus Vagnia is introduced for the single species V. cirriformia discovered on thalli of Peltigera in Poland; it appears to be a pathogen as the cortex is destroyed in a rounded patch within which the conidiomata occur. The fungus is characterized by cupulate to doliiform conidiomata clothed in white hairs and from which a black columnar cirrus of conidia arises. The simple ellipsoid conidia are hyaline when viewed individually and are formed enteroblastically from elongate conidiogenous cells supported by branched conidiophores.
