Holotype - Brazil, Rio Grande do Sul State, Municipality of Vacaria, Fazenda da Estrela locality, open field, 28º04'01.8''S, 50º57'45.4''W, 920 m alt., on basaltic rock, col. L.S. Canêz & A.A. Spielmann 892, 13-I-2003 (SP). Original description (Canêz, L.; Marcelli, M.P.; Elix, J.A. 2009, Mycotaxon 110: 467) Canoparmelia consanguinea Marcelli, Canêz & Elix, sp. nov. Fig. 1a MycoBank MB 515127 Thallus greenish gray (buff in herbarium), lobate to sublaciniate, to 8.5 cm wide. Lobes irregularly branched, (0.8-)1.6-3.0 mm wide, loosely adnate, contiguous, slightly overlapping, apices rounded, margin smooth to crenate, plane to involute, sometimes slightly elevated at the apices; surface continuous to slightly irregularly cracked in the center, smooth, shiny. Lacinulae and Pustulae absent. maculae reticulate, evident on the distal areas. Soralia orbicular, laminal and marginal, blackish when old; soredia granular, persistent, agglutinated, soon forming corticate granules which may develop into irregular pseudoisidia or small lobules in the older parts of the thallus. Medulla white, K+ purple pigment absent. Lower surface black, dull to a little shiny, papillate, smooth in some parts; marginal zone brown, 0.9-2.5 mm wide, smooth to papillate, rarely rugose; rhizines black, some with whitish apices, simple to penicillate, 0.20-1.25 x 0.05-0.10 mm, dense to frequent. apothecia very rare, plane, adnate, submarginal, imperforate, 2.7 mm diam.; margin smooth to sorediate, amphithecium sorediate. Ascospores ellipsoid, 10.0-12.5 x 5.0-6.0 µm, epispore 1.0 µm wide. Pycnidia submarginal, ostiole black, immature; conidia not seen. Spot tests: cortex K+ yellow, UV-; medulla K- (milky), C+ rose, KC+ rose, P+ pale yellow, UV+ pale blue. TLC/HPLC: Atranorin (±trace), olivetolcarboxylic acid (major), decarboxynorstenosporic acid (major), 4-O-demethylstenosporic acid (major), divaricatinic acid (minor), decarboxyanziaic acid (trace), decarboxystenosporic acid (minor), perlatolic acid (minor), decarboxyperlatolic acid (minor), depsidellin B (minor), depsidellin C (minor), divaricatic acid (minor or trace), subdivaricatic acid (trace), norsubdivaricatic acid (trace). Canoparmelia consanguinea is characterized by orbicular soralia, a C+ rose medullary reaction, and a complex medullary chemistry. In addition, this species has granular soredia, which often form corticate granules that may develop into irregular pseudoisidia or lobules. Canoparmelia consanguinea is morphologically similar to C. sanguinea, which also reacts C+ red (hence the name) and produces a very similar cohort of lichen acids, namely olivetolcarboxylic acid (minor), 4-O methylolivetolcarboxylic acid (minor), glomelliferic acid (minor/absent), glomellin (trace/minor), decarboxyanziaic acid (major), decarboxystenosporic acid (minor), decarboxyperlatolic acid (minor), divaricatinic acid (minor), depsidellin B (minor), unknowns (minor) (Benatti et al. 2009). However, C. sanguinea has true isidia rather than soredia. The new species C. subroseoreagens (described below) also produces soredia and reacts C+ rose but has a different chemistry, a peculiar upper surface, and a very unique means of producing soredia. In the field, C. consanguinea might be confused with C. texana (Tuck.) Elix & Hale, a very abundant lichen in Brazil, since both species have orbicular soralia. However, C. texana has a much simpler chemistry, producing only divaricatic acid (C-, KC+ purplish) in the medulla.
