Viegasella and Mintera, two new genera of Parmulariaceae (Ascomycota), with notes on the species referred to Schneepia

Two species previously accommodated in the genus Schneepia, S. pulchella and S. reticulata, are shown to belong to distinct new genera, described here as Viegasella and Mintera respectively. The new taxa are compared with Parmularia (of which Schneepia is confirmed as a synonym) and Symphaeophyma. F...

More Information
Summary:Two species previously accommodated in the genus Schneepia, S. pulchella and S. reticulata, are shown to belong to distinct new genera, described here as Viegasella and Mintera respectively. The new taxa are compared with Parmularia (of which Schneepia is confirmed as a synonym) and Symphaeophyma. Features of internal and external stromata, haustoria and stromata are emphasized as important characters for generic delimitation in the Parmulariaceae. The disposition of the remaining species assigned to Schneepia is discussed.
