Amorosia littoralis gen. sp. nov., a new genus and species name for the scorpinone and caffeine-producing hyphomycete from the littoral zone in The Bahamas.
The new generic and species name Amorosia littoralis gen. sp. nov. is introduced for the conidial dematiaceous hyphomycete isolated from the littoral zone in The Bahamas and reported in 2001 to produce the novel aza-anthraquinone scorpinone, and also caffeine. No satisfactory generic placement was found at the time, but subsequent morphological and molecular investigations reveal that a new generic name is required. The new genus has some similarity to several fungi described in Trichocladium, but differs substantially from the type species of that genus in the form of the conidia and the lack of ornamentation. BLAST studies using the 18S and 28S rDNA gene sequences place the new genus in the Sporormiaceae. In addition to the morphological studies, an ultrastructural examination of the conspicuous porate septa of hyphae showed that they do not belong to a basidiomycete.
