Species description:
Thallus small to medium but not minute; lobes averaging to more than 1.5 mm wide, always dorsiventral; isidia present or absent, distinctly wrinkled upper surface AND
Lobe margins naked; isidia, if present, naked AND
Lobes broad or, if elongate, then never both erect and terminating in distinctly swollen tips; lobe tips averaging to less than 0.2 mm thick when moist, seldom strongly wrinkled when dry; habitat and distribution various AND
Lower surface naked or bearing scattered tufts of hair at points of attachment, never distinctly woolly AND
Isidia and lobules absent over upper surface AND
Lobes short or elongate, margins not at all turned under; lobe tips not at all horn-shaped AND
Upper surface bearing strongly raised wrinkles; lobe margins strongly lobulate to finely divided-isidiate


Thallus minute; lobes averaging to less than 1 mm wide, occasionally cylindrical; true (i.e., basally constricted) isidia absent AND
Thallus entirely or largely consisting of dorsiventral lobes (check basal primary lobes) AND
Not associated with Em>Peltigera venosa AND
Upper surface usually somewhat wrinkled; thallus consisting of non-cellular interior surrounded by cellular outer cortex AND
Lobe margins strongly lobulate to finely divided-isidiate
L. californicum appears to freely intergrade with L. lichenoides,typically a much more wrinkled and lacerate species. Further work is needed.
