Synonyms:

Family: ICMADOPHILACEAE

Habitat: Montane

Description

    Thallus crustose, soft, granular to slightly warted, grey-green, grey-bluish when dry, greenish when moist. Apothecia scattered all over the thallus, 1-2.5 mm diam., sessile, as laying down on the thallus, seldom on top of a very short stalk, disc flat at first, exciple white-pink, pruinose, soon convex turning globose more or less distorted, pink, pink-orange, slightly pruinose. Ascii (6)-8-spored, narrowly cylindrical, 110-150 x 12-15 µm according to our measures. Ascospores narrrowly ellipsoid, colourless,  1-septate, seldom 2-3-septate, 13-27 x 4-6 µm according to literature, 17-28 x 4-7 µm according to our measures. Photobiont: Coccomyxa. Thallus : C-, K+ yellow > dark orange, Pd+ orange ; apothecia : K+ yellow > brown-yellow. Strong mountainous trends, on humid grounds enriched in plant debris (peatlands) or on wood under decomposition. This species was mentioned in Brittany but has not been found recently. This suggest either its disappearence or a misidentification since it is rather similar to Dibaeis baeomyces of which the pink apothecia are hollowed and stalked.
