About: Vermilacinia varicosa

Vermilacinia varicosa is a fruticose lichen known from two islands along the Pacific Coast of central Baja California, Isla San Roque located just off the southern Vizcaíno Peninsula west of Bahía Asuncón and Cedros Island where found on precipitous rocks along the northwest coast. The epithet, varicosa, is in reference to the unusually dilated type of branch in the genus. The lichen was first collected by Joseph Nelson Rose on 15 March 1911 during the Albatross Expedition. His lichen specimens had been kept separate from the mounted and filed lichen collections in the herbarium at the Smithsonian Institution, Department of Botany, US) loose in brown standard herbarium paper, and were made available to Richard Spjut sometime after 1986 while he was undertaking a revision of the genus Nieb
