Abstract:

The species of the genus Fuscidea occurring in North America are revised. Two new species, Fuscidea appalachensis Fryday and F. texana Fryday, are described from eastern North America and southern Texas, respectively. Three new combinations are also made in Fuscidea: Lecidea aleutica Degel. is shown to be a distinct species and not a synonym of Fuscidea lowensis (H. Magn.) R. Anderson & Hertel as previously suggested and is here recognized as F. aleutica (Degel.) Fryday; non-sorediate, apotheciate specimens from eastern North America previously referred to F. recensa (Stirt.) Hertel, V. Wirth & Vězda are recognized as Fuscidea recensa var. arcuatula (Arnold) Fryday; and Fuscidea scrupulosa (Eckf.) Fryday is shown to be the correct name for Fuscidea subreagens (H. Magn.) Oberholl. & V. Wirth. Fuscidea subfilamentosa (Zahlbr.) Brako is shown to be a member of the Lecidea hypnorum group and the new combination Lecidea subfilamentosa (Zahlbr.) Fryday is made, and Lecidea gyrodes H. Magn., described from Tennessee, is shown to be a synonym of F. recensa var. arcuatula. Fuscidea cyathoides (Ach.) V. Wirth & Vězda, F. kochiana (Hepp) V. Wirth & Vězda and F. lightfootii (Sm.) Coppins & P. James are considered not to have been correctly reported from North America.
