Notes on African Pannariaceae (lichenized ascomycetes)

Abstract

AbstractThe African continent is shown to contain only 38 species in the lichen family Pannariaceae, all of which are listed in the conclusion. Four new species are described: Pannaria planiuscula (Republic of South Africa [RSA] and Kenya), Pannaria squamulosa (RSA), Parmeliella dactylifera (RSA), and Parmeliella triptophylloides (Kenya). Four species are recorded as new to the continent: Pannaria centrifuga P.M. Jørg. (RSA), Pannaria ramosii Vain. (Tanzania), Parmeliella imbricatula (Müll. Arg.) P. M. Jørg. (RSA), and Psoroma fruticulosum James & Henssen (RSA). The following taxa described from Africa prove to be synonyms: Pannaria cameroonensis Dodge (=Parmeliella stylophora), Pannaria capensis Stirt. (= P. lurida), Pannaria leucosticta var. isidiopsis Nyl. (= P. globigera), Pannaria pityrella Stirt. (= Coccocarpia stellata), and Pannaria thoroldii Dodge (= Parmeliella mariana). Three species have been incorrectly recorded from Africa: Pannaria fulvescens, Parmeliella nigrocincra and Parmeliella triptophylla.
