Lobarina scrobiculata (Scop.) Cromb.
Nyl. ex Cromb., Monogr. Lich. Brit. 1: 270, 1894. Basionym: Lichen scrobiculatus Scop. - Fl. Carn., ed. 2, 2: 384, 1772.
Synonyms: Lobaria scrobiculata (Scop.) DC.; Lobaria verrucosa (Huds.) Hoffm.; Lobaria verrucosa f. esorediosa Gyeln.; Lobarina scrobiculata (Scop.) Nyl.; Parmelia scrobiculata (Scop.) Ach.; Sticta scrobiculata (Scop.) Ach.
Description: Thallus foliose, broad-lobed, heteromerous, dorsiventral, loosely attached, 10-16 cm wide, the lobes rounded at apex, contiguous to imbricate, 10-30 mm wide, with entire to slightly crenulate margins. Upper surface blue-grey to yellowish grey when dry, dark blue-grey to blue-green when wet, undulate, coarsely reticulate-areolate but without defined ridges, scabrid espèecially in marginal parts due to pyramidal, c. 0.06 mm wide granules, sorediate. Soralia blue-grey, mainly laminal, punctiform at first, but eroding with age and becoming circular; soredia granular. Lower surface with glabrous, whitish patches separated by a pale brown, silky, entangled tomentum, erhizinate or with very sparse, simple rhizines. Upper and lower cortex paraplectenchymatous, the lower cortex poorly developed; medulla white. Apothecia very rare, 1-2 mm across, with a concave, red-brown disc and a verruculose, inflexed, often sorediate thalline margin. Asci 8-spored, fissitunicate, the thickened apex with a K/I+ blue ring, Peltigera-type. Ascospores (1-)3(-7) septate, hyaline, elongate-fusiform, (40-)50-80 x (4-)6-7 µm. Photobiont cyanobacterial (Nostoc, the cells in short chains). Spot tests: cortex K- or K+ faintly yellow, C-, KC-, P-; medulla K- or K+ yellow-orange, C-, KC- or KC+ orange-red, P- or P+ orange, UV+ violet. Chemistry: chemotype 1 has usnic and stictic acids plus scrobiculin and sometimes traces of norstictic acid; chemotype 2 lacks stictic acid.
Growth form: Foliose, broad lobed
Substrata: bark
Photobiont: cyanobacteria, filamentous (e.g. Nostoc, Scytonema)
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
