Phylogenetic and morphological characterization of Byssosphaeria macarangae sp. nov., and B. taiwanense sp. nov. from Macaranga tanarius

Abstract

Byssosphaeria species were collected from Macaranga tanarius (Euphorbiaceae) in Shihnong forest area in Chiayi, Taiwan and subjected to morphological examination and DNA sequence analyses. Two new taxa, Byssosphaeria macarangae sp. nov and B. taiwanense sp. nov are herein described. Both species can be distinguished from other Byssosphaeria species based on distinct size differences in asci, ascospores and DNA sequence data. Detailed descriptions, micrographs and phylogenetic data of the new species are provided.
