Description

    Thallus crustose, thin and inconspicuous, without distinct margin, continuous to slightly cracked, pale grey with pink or orange tinge. Apothecia up to 1 mm diam., globose, then, when opened with a pale orange disc, margin thick, crenulate, pale cream-orange (flower-like). Ascospores broadly ellipsoid, 3-septate, becoming muriform, 12-25 x 6-10 µm (30-40 x 10-16 µm for var. macrospora). Photobiont: Trentepohlia. Chemical spot tests negative. Usually on damp shady hard limestones and consequently rather rare in our prospection area.  However in our region Gyalecta jenensis var. macrospora  may be found on weakly acid rocks near the seashore or on damp shaded old walls with stones and mortar. N.B. Evokes small orange jam tartlets.
