Abstract

Lecanographa insolita is described as new to science based on collections from the Channel Islands of southern California and an isolated coastal redwood forest in central California, U.S.A. Placement of this normally sterile species in the genus Lecanographa is supported by secondary chemistry and the anatomy of sterile ascoma found on a single thallus. The species has a non-filament forming coccoid photobiont rather than Trentepohlia, an apparently unique feature within the genus Lecanographa as well as the broader context of the Roccellaceae. Comparison is drawn to other members of the Roccellaceae that have byssoid thalli.
