A lichenicolous species of Pleospora (Ascomycota) and a key to the fungi invading Physcia species

摘要

The new combination Pleosporaphysciae (Brackel) Hafellner & E.Zimm. (bas. Merismatiumphysciae Brackel 2010) is introduced. An emended description is given and the species, which is a pathogen on various epiphytic Physcia species is newly reported forthe mycoflora of Austria, Slovenia and Switzerland. Two further nomenclatural novelties are proposed, the new name Pleospora tretiachii Hafellner (bas. Pleospora aquatica Tretiach & Nimis 1999 non Griffiths 1899) and the new combination Lichenochora physciicola (Ihlen & R.Sant.) Hafellner (bas. Telogalla physciicola Ihlen & R.Sant.). A key to the lichenicolous fungi occurring on Physcia species is provided.
