Parmotrema reticulatum (Taylor) M. Choisy
Bull. Mens. Soc. Linn. Lyon, 21: 175, 1952. Basionym: Parmelia reticulata Taylor in Mackay - Fl. Hibern., 2: 148, 1836.
Synonyms: Parmelia amphigymnoides Gyeln.; Parmelia cetrata auct. p.p. non Ach.; Parmelia concors Kremp.; Parmelia decorata (Hue) C.W. Dodge; Parmelia diffusoides Gyeln.; Parmelia odontata var. rubiginosa Sambo; Parmelia ornata (Hue) C.W. Dodge; Rimelia reticulata (Taylor) Hale & A. Flechter
Description: Thallus foliose, heteromerous, dorsiventral, broad-lobed, loosely attached, 4-20(-30) cm in diam., sorediate. Lobes elongate, slightly overlapping, 5-15 mm wide, crenate at margins, rounded and sometimes subascending at apices, the margins thin, with black, simple, up to 3 mm long cilia, sometimes eciliate. Upper surface pale grey to grey-green, smooth, dull, strongly reticulately white-maculate, with mostly marginal, convex to subcapitate soralia which often arise on small lacinulate lobes (sometimes becoming diffuse in old specimens). Lower surface black, with a narrow, papillate and erhizinate zone at margin, centrally with mostly simple, black rhizines. Upper cortex of tightly packed, anticlinally oriented hyphae, with a pored epicortex, the cell walls with lichenan intermediate between the Cetraria- and the Xanthoparmelia-types; medulla white; algal layer continuous; lower cortex prosoplectenchymatous, with rounded and thick-walled cells. Apothecia extremely rare, lecanorine, submarginal, substipitate, up to 8 mm across, with a sometimes perforate, brown disc and a raised thalline margin. Epithecium brownish; hymenium and hypothecium colourless. Asci 8-spored, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid, 10-18 x 7.5-11 µm. Pycnidia rare, punctiform, black, immersed. Conidia filiform, (7.5-)12-16 x 1-1.5 µm. Photobiont clorococcoid. Spot tests: upper cortex K+ yellow, C-, KC-, P- or P+ faintly yellow; medulla K+ yellow turning orange-red, C-, KC- or KC+ red, P+ orange-red, UV-. Chemistry: upper cortex with atranorin and chloroatranorin; medulla with salazinic acid (major) and consalazinic acid (minor).
Growth form: Foliose, broad lobed
Substrata: bark
Photobiont: green algae other than Trentepohlia
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)
