Schizopelte lumbricoides image
Thallus: subfruticose to subfoliose, solid lobes: marginal parts c. globular; central parts often with ± terete but c. dorsivental towards the tips, lumbricoid (worm-like), appressed branches lobe surface: creamy-white to ivory white, smooth; soredia absent medulla: white with lowermost parts brown or yellowish brown Ascomata: numerous, lirelliform with branched lirellae; hymenium: 60 µm high; paraphysoids: reticulately and richly branched, conglutinated, hyaline, c. 1 µm in diam. asci: clavate, c. 75 x 13 µm, 8-spored ascospores: fusiform, 3-4 septate, hyaline, 15-18 x 4-5 µm Spot tests: cortex K-, C+ red, KC+ red, P-; medulla K-, C+ red, KC+ red, P- Secondary metabolites: erythrin and lecanoric acid (both major); montagnetol and orsellinic acid (both minor); three other minor substances are probably hydrolysis or methanolysis products. Substrate and ecology: on vertical rocks and cliffs near the ocean; individuals often growing in masses covering several square meters World and Sonoran distribution: only known from a few localities on the Baja California mainland and on Guadalupe Island. Notes: Hubbsia californica is characterized by its solid thallus with lumbricoid lobes in the central parts and the complete absence of soredia.
