The new species Roccella ramitumidula is described from a tropical dry forest in the Pacific
Coast of Mexico. The new species is characterized by fertile thalli, saxicolous habit, irregularly swollen
branches and erythrin and lecanoric acid as lichen products. It differs from R. decipiens by its narrower
and longer ascospores, irregularly swollen branches, uneven surface, and smaller branches. Sequences of
the genetic markers ITS, nuLSU and RPB2 from the new species were added to a phylogenetic tree based
on four genetic markers that included all the Roccella species known for the Americas. The biogeography
and ecology of the species is discussed. We reported R. gracilis for the first time for the state of Jalisco,
Mexico.
