title: Talaromyces neofusisporus and T. qii, two new species of section Talaromyces isolated from plant leaves in Tibet, China.
abstract: Two new species isolated from plant leaves belonging to Talaromyces section Talaromyces are reported, namely T. neofusisporus (ex-type AS3.15415 (T) = CBS 139516 (T)) and T. qii (ex-type AS3.15414 (T) = CBS 139515 (T)). Morphologically, T. neofusisporus is featured by forming synnemata on CYA and YES, bearing appressed biverticillate penicilli and smooth-walled fusiform conidia about 3.5-4.5 × 2-2.5 μm; and T. qii is characterized by velutinous colony texture, yellowish green conidia, yellow mycelium and ovoid to subglobose echinulate conidia measuring 3-3.5 μm. Phylogenetically, T. neofusisporus is such a unique species that no close relatives are found according to CaM, BenA and ITS1-5.8S-ITS2 as well as the combined three-gene sequences; and T. qii is related to T. thailandensis according to CaM, BenA and the combined sequence matrices, whereas ITS1-5.8S-ITS2 sequences do not support the close relationship between T. qii and T. thailandensis.
