Abstract
Summary. Phaeohyphomycosis is an umbrella term for all those mycoses where the fungus is present in tissue with melanized filaments. It is surmised that some groups of species within the ascomycete family Herpotrichiellaceae exhibit an evolutionary tendency towards pathogenicity on vertebrate hosts. Such a tendency is not observed in the families Pleosporaceae and Dothideaceae. Mycoses provoked by members of the three families thus may be fundamentally different. Phaeohyphomycosis should be regarded as an artificial descriptor without biological significance.Zusammenfassung. Phaeohyphomykosen sind Mykosen, bei denen der Pilz im Gewebe melanisierte Fila‐mente ausbildet. Es gibt Hinweise, dass bei einigen Erregerarten, die in die Ascomyzetenfamilie Herpotrichiellaceae gestellt werden, eine evolutionäre Tendenz zur Pathogenität in Vertebraten besteht. Eine solche Tendenz ist bei den Familien Pleosporaceae und Dothideaceae nicht ersichtlich. Mykosen durch Mitglieder dieser drei Familien könnten daher grundverschieden sein. Phaeohyphomykose sollte besser als rein deskriptiver Begriff ohne biologische Bedeutung aufgefaßt werden.Keywords
