Synonyms: Collema multipartiens Nyl.; Lathagrium muelleri (Hepp) Arnold; Lathagrium multipartitum (Sm.) Kremp.; Lathagrium turgidum (Körb.) A. Massal.; Parmelia turgida (“Ach.”) Schaer. non Collema turgidum Ach.; Synechoblastus multipartitus (Sm.) Körb.
Description: Thallus small-foliose, homoiomerous, gelatinous when wet, forming 1-3(-6) cm wide rosettes. Lobes radiating, adpressed, rather loosely attached, linear to fan-shaped, usually convex, dull, dark olive-brown to black, often minutely striated, repeatedly dichotomously branched, 0.5-1.5(-2) mm wide, much swelling when wet (up to 350 µm thick), not pubescent, without isidia. Lower surface usually paler, with tufts of white hapters. Upper and lower cortices absent. Apothecia frequent, lecanorine, sessile, 1-2 mm across, with a flat to slightly convex, brown-black disc, and a usually thin, persistent, smooth or crenulate-lobulate thalline margin. Thalline exciple ecorticate; proper exciple 100-150 µm thick laterally, euparaplectenchymatous; epithecium brownish; hymenium colourless, 90-120 µm high, I+ blue; paraphyses simple or sparingly branched in upper part, 2-4.5 µm thick at mid-level, the apical cells slightly wider; hypothecium pale brown, I+ blue. Asci 8-spored, cylindrical-clavate, the apex strongly thickened, the apical dome K/I+ pale blue, with a downwardly projecting K/I+ deep blue tubular structure. Ascospores 3(-4)-septate, hyaline, linear-oblong, often curved at maturity, (20-)25-45(-50) x 4.5-6.5 µm. Pycnidia usually laminal, immersed, globose, pale with darker apex. Conidia bacilliform, straight, slightly swollen at both ends, 4.5-7 x 1-1.5 µm. Photobiont cyanobacterial (Nostoc, the cells in chains). Spot tests: all negative. Chemistry: without lichen substances.
