| Abstract: | Two new species of hyphomycetes,Xenocylindrocladium guianense andX. subverticillatum, are described from plant debris collected in French Guiana and Singapore, respectively. The genusXenocylindrocladium has thus far been known from one species,X. serpens, which was described from plant debris collected in Ecuador. The two new taxa are compared with and distinguished fromX. serpens based on morphology, cultural characteristics and phylogenetic analysis of DNA sequence data of the 5.8S rDNA with flanking ITS1 and ITS2 regions and the 5′ end of the β-tubulin gene. These species are also compared with other closely related hypocrealean taxa. Present collection data suggest that species ofXenocylindrocladium could be restricted to the tropics. |
