Devil's Matchstick

"The pseudopodetia (upright stalk-like extensions of the thallus made of vegetative tissue) range from 0.5 to 3 cm (0.2 to 1.2 in) high, and are about 1 mm thick; they grow in dense clusters. Most pseudopodetia are either unbranched or forked into two branches, with the stalks curved so as to appear as if combed; less frequently, they are erect like pins, and up to 1 cm (0.4 in) tall.
The thallus is the vegetative body of a lichen that contains the lichen mycobiont (fungus) and the photobiont (algae and/or cyanobacteria). In P. acicularis, the primary thallus (thallus horizontalis) is spread out like a granular crust on the surface of its substrate. It is light green when young, but becomes gray in age or when dry."
