in Brown & al. (eds.), Lichenology: Progress and Problems: 91, 1976. Basionym: Lecidea aestivalis Ohlert - Schr. phys- ökon. Ges. Königsb., 10: 16, 1870.
Synonyms: Biatora aestivalis (Ohlert) Lindau; Catillaria byssacea Vězda; Pachyascus byssaceus (Vězda) Vězda
Description: Thallus crustose, dull green to dark olive-green, thinly episubstratic or semi-immersed, entirely consisting of up to 40 μm wide, corticate goniocysts with short conical outgrowths (microscope!). Apothecia short-lived, without a proper margin, convex, appressed or immersed in the thallus, 0.3-0.8(-1) mm across, whitish, grey or reddish brown, often appearing finely tomentose when dry (microscope!). Proper exciple absent; hymenium lacking gelatine, consisting of branched and anastomosing, strongly contorted paraphyses entwining the individual asci; hypothecium absent. Asci 8-spored, cylindrical, thick-walled, with a thick I+ blue apex (except for an apical pore). Ascospores 1(-3)-septate, hyaline, ellipsoid, thick-walled, with a minutely verrucose surface at maturity, 15-20(-22) x 5-7(-8) μm. Photobiont chlorococcoid (Leptosira). Spot tests: all negative. Chemistry: without lichen substances.
Growth form: Crustose
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly sexual
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
Pioneer species
