Description

Green to whitish thallus continuous, glossy to matte; hyphophores about 0.5 mm long if stretched out, black, gracefully curved (akin to a Mute Swan neck), expanded near top into a lanceolate to ovate shape, with a noticeable bundle of white diahyphae beneath the blade; young hyphophores pale and translucent, more upright; MICROSCOPY: diahyphae colorless, long, slender, with unconstricted septa between cells, 1 end wider, the other tapering to a tail; FIELD ID possible to genus, due to lookalike; requires dissection to observe diahyphae

Similar Species
