sp. nov. and sp. nov., two endophytes from in China.

Background: Tratt., a deciduous shrub of the family Rosaceae, is usually used as food and medicinal materials and also cultivated as an ornamental. Plant endophytic fungi are a large class of microbial resources not fully researched, with great potential applications. Two strains of and were isolated during a survey of biodiversity on endophytic fungi of in China. Multigene phylogenetic analyses showed that each of the two fungi formed a distinct lineage and separated from known congeneric species and they are proposed as two novel taxa.

New Information: sp. nov. usually has one or two conspicuous simple or branched ridges extending to the majority of the ascospore surface and remarkably small asci, distinguishing it from the previously-described species in the genus . sp. nov., of the section Talaromyces, is closely related to . It differs from the latter by having both monoverticillate and biverticillate conidiophores, while those of are biverticillate. Both novel endophytes are illustrated and described.
