Ramboldia blochiana
Ramboldia blochiana is a bark-dwelling crustose lichen in the Ramboldiaceae family. Described in 2011 by Lendemer and Harris, it is the sorediate counterpart of Ramboldia russula, sharing chemistry and apothecial form but with its own distinctive chemicals and distribution. The thallus is creamy white to dark gray, can be thin or thick with irregular patches, and produces soredia from pustular soralia. Apothecia are bright red (biatorine) and become irregular as they mature; ascospores are hyaline, narrowly ellipsoid, and non-halonate. Chemical compounds include lichexanthone, fumarprotocetraric acid, secalonic acid, and russulone. Ramboldia blochiana grows on various corticolous substrates such as Pinus bark, Vellozia, Vaccinium, and wood. It is found in tropical and subtropical regions of the New World, with confirmed records in Brazil, Venezuela, the Dominican Republic, Haiti, parts of the southeastern United States and the southern Appalachians, and Mexico. The type specimen came from Bahia, Brazil, on Pico das Almas, and the name honors Ellen D. Bloch. The authors note that the species might have a broader distribution than currently known because many sterile crustose lichens are undercollected.
