Listedit
Acarospora fuscata (Schrader) Arnold [Acarosporaceae]
Skorepa et al. (1979) – on acidic rock.
E.G. Worthley Herbarium - Carroll Co., on stone wall.
Lichenodiplis lecanorae (Vouaux) Dyko & D. Hawksw. [Anamorphic Ascomycetes]
E.C. Uebel Herbarium – Baltimore Co., Liberty Reservoir, a specimen of Pertusaria xanthodes U-243, was collected growing on a small dead oak branch. This crustose lichen contained a lichenicolous fungus and a sample of this fungus was sent to the Farlow Herbarium where it was forwarded to Dr. David Hawksworth, who identified it as Lichenodiplis lecanorae.
Lobaria pulmonaria (L.) Hoffm. [Lobariaceae]
Skorepa et al. (1979) – on bark.
Biechele (2002) – lower eastern shore of Maryland.
E.G. Worthley Herbarium - Frederick Co., Cunningham Falls.
Lobaria quercizans Michaux [Lobariaceae]
Skorepa et al. (1977) – Garrett Co., on trunk of deciduous tree.
Skorepa et al. (1979) – on bark.
Biechele (2002) – lower eastern shore of Maryland.
E.G. Worthley Herbarium - Frederick Co., Cunningham Falls.
E.C. Uebel Herbarium – a specimen of Violet Toothed Polypore [Trichaptum biforme (Fries) Ryvarden] was collected with Flavoparmelia caperata (U-65) growing on the bark of a fallen oak tree at Liberty Reservoir in Baltimore County. The T. biforme had a stubble lichen growing on it which was identified by Dr. Steven Selva as Phaeocalicium polyporaeum.
