About plant names...

Identification: Grayish white or grayish green, with tiny gray “warts.” Occurs on the wood or bark of deciduous trees. This is a crustose lichen (a thin layer that almost looks like paint), but thicker than most. The apothecia (fruiting bodies) are shiny black dots less than ⅛" (3.2 mm) across. There is a bright red zone underneath (the reason for the name “bloody heart lichen”), but you’ll need to slice into it to see it. (I don’t know what the red-brown region is on the photo at right—I don’t think it is part of the lichen.)

Mycoblastus sanguinarius (Bloody Heart Lichen, Blood Lichen)

Photograph of a herbarium specimen taken through a dissecting microscope (x8) shows a bright red pigment in a cut apothecium. M. sanguinarius was growing on a dead branch along the trail up Black Mountain, S of Tunk Lake, NE of Ellsworth, Hancock County, Maine, USA (44o35’ N., 68o06’ W); collected by E.C. Uebel, identified by Dr. Irwin Brodo (No. U-515, 11 Jul 2005).
