Bulbothrix linteolocarpa Marcelli

Thallus sublinear laciniate, dusky gray in the herbarium, up to 2.6 cm diam., subcoriaceous, corticolous; upper cortex 20.0−30.0 µm thick, algal layer 55.0−75.0 µm thick, medulla 25.0−35.5 µm thick, lower cortex 10.0−15.0 µm thick. Laciniae irregularly to anisotomically dichotomously branched, 0.2–0.6 (-0.8) mm wide, contiguous to occasionally slightly imbricate, adnate and adpressed, with flat, truncate apices; margins flat, smooth to sinuous or subirregular, entire to slightly incised and rarelly sublacinulate; axils oval to irregular. Upper cortex continuous, smooth to subrugose; laminal ciliary bulbs absent. Adventitious marginal lacinulae scarce on older parts, short, 0.1–0.6 × 0.05–0.20 mm, plane, simple; apices truncate; lower side concolor to the lower marginal zone. Maculae absent. Cilia black to brown, with simple to partially furcate apices, often bent downwards, 0.05–0.45 × ca. 0.03 mm, with semi- immerse to emerse bulbate bases ca. 0.05–0.10 mm wide, frequent along the margins, spaced 0.5–0.10 mm from each other rarely becoming contiguous at the axils, usually absent or scarce on the apices of the laciniae. Soredia, Isidia and Pustulae absent. Medulla white. Lower surface pale brown, shiny, smooth, weakly papillate, moderately rhizinate. Marginal zone pale brown, slightly darker than the center, shiny, attenuate, 0.5–1.0 mm wide, smooth, weakly papillate, sligthly rhizinate. Rhizinae light to dark brown or almost blackish, simple to occasionally furcate or irregularly branched, often with dark basal or displaced bulbs, 0.05–0.60 × ca. 0.03–0.05 mm, frequent, becoming scarce at some parts, partially agglutinated, evenly distributed. Apothecia subconcave, becoming plane or convex, stretching over the laciniae while maturing, adnate, 0.3−3.4 mm diam., laminal, ecoronate; margin smooth to incised and subcrenate; amphitecium smooth, without ornamentations. Disc brown, epruinose, imperforate; epithecium 12.5–20.0 mm high; hymenium 37.5−45.0 µm high; subhymenium 15.0−20.0 µm high. Ascospores ellipsoid to oval, (9.0−) 10.0−16.0 × 6,5−8,0 µm; epispore ca. 1.0 µm. Pycnidia not found. TLC/HPLC: cortical atranorin and chloroatranorin, medullary salazinic, consalazinic and secalonic A acids (label from J. A. Elix with the holotype, 19-VII-1995).
