Very compact.
Very small.
Apothecia adorned with compact branches.
This had fallen from the forest canopy and was on the ground long enough for slugs to eat the surface of the apothecia of the Physcia stellaris (on the left, and right), rendering the apothecia a peculiar shade of green. The apothecia of the Ramalina americana are intact, strongly suggesting they are inedible to gastropods (slugs and snails).

Collected with Coastal Plains Outdoor School - Winter Mushrooms Program
Forming applanate/appressed (ie: not shelving), distinctly filamentous thalli against standing, living tree.
Portions of hymenium possibly embedded in a gelatinous matrix (see image 6). IKI reactions non-descript, possible dextrinoidity in some hymenial structures (asci?).
Paraphyses abundant, clavate, multi-septate, with refractive golden yellow contents concentrated in lower 2/3rds of length, broadly inflated at apices/terminal cell, minutely exceeding asci.
Excipulum composed of globose to angular cells
Spores narrowly ellipsoid to broadly fusiform, 1-septate, with contents (some bi-guttulate), often curved, inequilateral, minutely cinched at septum. Measurements below:

On a dead branch of Fraxinus americana. Thalli are whiter and more sorediate on the upper side of the branch, where there was more sun exposure.
