Abstract

A newTalaromycesspecies,T.amyrossmaniae, isolated from decaying fruit and litter ofTerminalia bellerica, is described and illustrated. On the natural substrate, the new species produces determinate synnemata, with a well-defined, vivid orange red to orange red cylindrical stipe, and a greyish green capitulum. Conidiophores are typically biverticillate, or sometimes have subterminal branches, with acerose phialides that produce globose to subglobose, smooth to slightly roughened conidia. Multigene phylogenetic analyses based on the internal transcribed spacer region (ITS), and partial sequences of β-tubulin (BenA), calmodulin (CaM), and DNA directed RNA polymerase second large subunit (RPB2) genes, along with morphological characterization, revealed that these isolates are distinct and form a unique lineage of Talaromyces in section Trachyspermi, closely allied toT.aerius,T.albobiverticillius,T.heiheensis,T.erythromellis, andT.solicola. The new speciesT.amyrossmaniaeis the first species in section Trachyspermi with determinate synnemata.
