[en] The biological status of Chiodecton epiphyllum (Arthoniales: Roccellaceae), described as a foliicolous lichen from Papua New Guinea, is reassessed, based on additional material from Brazil, Costa Rica, and Papua New Guinea. The species is a lichenicolous fungus growing on the foliicolous lichen Coenogonium flavicans (Gyalectales: Gyalectaceae). Furthermore, its ascomatal anatomy and lichenicolous growth habit suggest placement in the related genus Plectocarpon, instead of Chiodecton. We therefore propose the new combination Plectocarpon epiphyllum [Bas.: Chiodecton epiphyllum]. The species is further lectotypified on its ascomata since parts of the original description which denote vegetative characteristics refer to the sterile thallus of the host lichen.
