''Vermilacinia ligulata'' is an infrequent lichen found along the foggy Pacific Coast of Baja California in rock-walled narrow arroyos, on rocky peninsulas and on ridges within the Northern Vizcaíno Desert region, ranging from Punta Cono to just north of Punta Canoas, and along the east coast of Cedros Island.〔Spjut, R. W. 1996. ''Niebla'' and ''Vermilacinia'' (Ramalinaceae) from California and Baja California. Sida Miscellany 14〕 The species was first collected in May 1985 in the southern part of the northern peninsula of Baja California, about 100 km north of Guerrero Negro, 400 meters inland from the ocean on rocky walls with a northern exposure in a narrow estuary. The type is from the same locality but collected one year later, 19 May 1986.〔 ==Distinguishing features==
''Vermilacinia ligulata'' is distinguished by its thallus divided into relatively few basal branches, generally less than 10, although it may appear to have more by its gregarious habit, and by lacking a blackened base, not reaching more than 3 cm in height, appearing strongly crinkled and twisted with wavy branch margins (when dry), and by having lichen substances of triterpenes, referred to as T1 and T2, along with zeorin and (-)-16 α-hydroxykaurane; T3, which occurs in most related species, was not noted. Salazinic acid and usnic acid were also not reported. The branches are often partly tubular near base, and strap shaped above, initially creeping along the substrate for a short distance before ascending upwards, and frequently divided more or less in a digitate (palmate) fashion. The overall appearance is much like ''Niebla contorta'' as exemplified by the image of its type from near Bahía Asunción. These species are distinguished by the presence or absence of chondroid strands in the medulla, and by their chemistry, ''N. contorta'' has divaricatic acid and triterpenes not found in ''Vermilacinia''.〔
