Status

Among Maryland lichens, Blistered Navel Lichens are most similar to Rock Tripes (Umbilicaria). Rock Tripes typically have rhizines while Blistered Navel Lichens do not. In both cases, it is useful to carefully observe the upper and lower surfaces of the lichen for identification. There are two relatively frequent species of Blistered Navel Lichens in Maryland and some less-common species as well. All prefer stone substrates and are generally found in the mountains and piedmont of western and central Maryland.

Lasallia papulosa has a pale or dark brown, smooth lower surface and a rough upper surface with raised pustules. Lasallia pensylvanica has a nearly-black, roughened lower surface and a smooth upper surface with low pustules.

Where To Find

Relatively frequent in the mountains and piedmont. Usually found on stone surfaces.

Lasallia is a genus of lichen-forming fungi in the family Umbilicariaceae. The genus was circumscribed by François Victor Mérat de Vaumartoise in 1821.[1] The genus name Lasallia honours of Mr. Lasalle (born around 1820), who was a French gardener and botanist, who worked in Fontainebleau.[2] Early molecular phylogenetics analysis of internal transcribed spacer DNA showed that the genus was monophyletic.[3]

High performance liquid chromatography analysis of several Lasallia species revealed a number of secondary metabolites in this genus, including gyrophoric acid, lecanoric acid, umbilicaric acid, 7-chloroemodin, valsarin, skyrin, hiascic acid, and ovoic acid.[4]
