Three new species of Talaromyces sect. Talaromyces discovered from soil in China

Three new Talaromyces species isolated from soil are reported here, namely T . dimorphus (ex-type strain AS3.15692 T ), T . lentulus (ex-type strain AS3.15689 T ) and T . mae (ex-type strain AS3.15690 T ). T . dimorphus is characterized by biverticillate and monoverticillate penicilli, ampulliform phialides, slimy texture with sparse mycelial funicles and absent conidiogenesis on MEA. T . lentulus is featured by vivid yellow mycelium on Cz and MEA, absent conidiogenesis on CYA, and globose smooth-walled conidia. T . mae presents sparse conidia on CYA and YES, funiculous and floccose texture on MEA, and ovoid smooth-walled conidia. Both morphological and molecular characters show that T . dimorphus is unique and has no close relatives. Although T . lentulus and T . mae resembles T . adpressus and T . pinophilus very much, phylogenetic analyses of CaM , BenA , ITS and Rpb2 sequences all support their status as novel species.
