Hypogymnia physodes forme pycnidiée.

Synonyms:

Family: PARMELIACEAE

Habitat: Ubiquitous

Description

     This relatively frequent form constitutes the anamorph of the species, the pycnidia appear in the form of small rounded and regular dots, purplish-brown to blackish grouped (sometimes in abundance) at the end of the lobes, more or less immerged and never in relief. Colorless, cylindrical to spindle-shaped conidia 5-8 x 1 µm. Everywhere but most often in places where conditions are difficult.

N.B. Rather similar to the beginning of an infection by Lichenoconium erodens but the conidiomas of this species are less numerous, scattered over the entire host thallus, protruding, irregularly shaped and surrounded by a zone of brownish then blackish necrosis. They produce brownish subglobose conidia 2.5-3.5 µm in diameter. N.B. The pycnidia and conidiomas of Lichenoconium erodens can coexist on the same thallus.
