Milospium deslooveri Diederich & Sérus.

    Lichenized hyphomycete fungus (but probably beginning its growth on crustose Trentepohlia lichens). Mycelium embedded in the host thallus (at least initially) and barely visible, this species is revealed by the presence of small masses of brownish-black, black sporodochia containing conidiogenous cells. Conidia are unlobed, curved until they become helicoid, with 2-6 (7) more or less complete septa  delimiting pseudo-loculi with a greenish content in KOH and whose outer walls are thicker and blackish, 8-12 x 8-10 µm according to the literature, 8-13 x 8-11 µm according to our measurements. A very rare (or unnoticed?) species, occurring on the vertical walls of siliceous rocks (schists, sandstones, etc.).

_ See Milospium graphideorum, whose conidia are unseptate.
