Two new Ramicandelaber species from Taiwan

Abstract

Two new species of Ramicandelaber isolated from soil in Taiwan are described. Ramicandelaber fabisporus sp. nov. is characterized by having bean-shaped spores that are the smallest in the genus and also by the absence of lateral branches on the sporangiophores. Ramicandelaber taiwanensis sp. nov. is characterized by small, fusiform spores and it produces lateral branches that arise from the sporangiophores. Morphological characters and molecular phylogenetic analysis (D1/D2 domains of the LSU rRNA genes and ITS region) justify these new species of Ramicandelaber. A key is provided to the recognized species of Ramicandelaber.
