ABSTRACT
The tropical lichen genus Aciculopsora is still very poorly collected. Only
eleven collections are known worldwide. We present a molecular phylogenetic tree based
on mtSSU and nrITS sequence data from six Aciculopsora specimens. Our results corroborate
the monophyly of the genus. We conclude that Aciculopsora consists of three
species: A. cinerea, A. longispora comb. nov. (≡ Phyllopsora longispora, = A. salmonea
syn. nov.) and A. srilankensis sp. nov. Aciculopsora cinerea occurs in Brazil, A. longispora
in Argentina, Costa Rica, Ecuador, and Kenya, and A. srilankensis in Sri Lanka. As such,
the genus is new for the Paleotropics, Argentina and Ecuador.
