Two New Species of Talaromyces Sect. Trachyspermi Discovered in China

Two new species of sect. Trachyspermi isolated from soil are proposed, namely, T. albidus (ex-type AS3.26143 T ) and T. rubidus (ex-type AS3.26142 T ), based on the integrated taxonomic methods. Morphologically, T. albidus is characterized by slow growth, white gymnothecia, singly-borne asci and ellipsoidal echinulate ascospores. Talaromyces rubidus is distinguished by restricted growth, moderate to abundant red soluble pigment on CYA and YES, biverticillate penicilli, and commonly ovoid to globose echinulate conidia. The two proposed novelties are further confirmed by the phylogenetic analyses of the concatenated BenA-CaM-Rpb2- ITS sequence matrix and the individual BenA , CaM , Rpb2 and ITS sequence matrices. Talaromyces albidus is closely related to T. assiutensis and T. trachyspermus , while T. rubidus is in the clade containing T. albobiverticillius , T. rubrifaciens , T. catalonicus , T. heiheensis , T. erythromellis , T. halophytorum , T. pernambucoensis , T. solicola and T. aerius .
