Collema subflaccidum Degel.
Symb. Bot. Upsal., 20, 2: 140, 1974.
Synonyms: Collema subfurvum auct.
Description: Thallus foliose, homoiomerous, subgelatinous when wet, dark olive-green to almost black, dull, rather loosely attached, 3-6 cm wide. Lobes 0.5-1(-2) cm wide, thin when dry, 75-120 µm thick when wet, not swollen nor pustulate, more or less rotund at apex, often ascending. Upper surface with numerous simple, globose to rarely in part teretiform, c. 0.05-0.1 mm wide isidioid outgrowths. Lower surface usually somewhat paler than the upper surface, with scattered white hapters. Upper and lower cortex absent. Apothecia rare, lecanorine, laminal, constricted at base, 1.5(-2.5) mm across, with a reddish brown disc and a smooth but often pseudoidiate thalline margin. Thalline exciple thickly pseudocorticate; proper exciple rather thin, subpara- to euthyplectenchymatous; epithecium brownish; hymenium colourless, 90-130 µm high; paraphyses simple or sparingly branched, 2(-4) µm thick at mid-level, with clavate to subglobose tips; hypothecium colourless. 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-)5-7-septate, hyaline, narrowly fusiform to broadly acicular, 40-55(-65) x (3-)5-7 µm. Pycnidia rare, immersed, laminal, pale brown. Conidia bacilliform or with slightly swollen ends, (3-)4-4.5(-6) x 1-1.5(-1.8) µm. Photobiont cyanobacterial (Nostoc, the cells in long chains). Spot tests: all negative. Chemistry: without lichen substances.
Growth form: Foliose, broad lobed
Substrata: bark
Photobiont: cyanobacteria, filamentous (e.g. Nostoc, Scytonema)
Reproductive strategy: mainly asexual, by isidia, or isidia-like structures (e.g. schizidia)
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
