Three new species isolated from the tidal flats of China.

During a survey of culturable fungi in the coastal areas of China, three new species of sect. were discovered and studied with a polyphasic taxonomic approach, and then named as sp. nov. (ex-type AS3.15900 = LN5H1-4), sp. nov. (ex-type AS3.16039 = TT2-4X3, AS3.16040 = TT2-6X3) and sp. nov. (ex-type AS3.16038 = 0801H2-2, AS3.16207 = ZZ2-9-3). In morphology, is unique in showing light yellow sclerotia and mycelium, sparse sporulation, restricted growth at 37 °C, irregular conidiophores, intercalary phialides and metulae, and pyriform to subspherical conidia. is distinguished by the fast growth on CYA and YES and slow growth on MEA at 25 °C, weak or absence of growth at 37 °C, biverticillate and monoverticillate penicilli, and ellipsoidal conidia. is characterized by abundant grayish-green conidia and moderate growth at 37 °C, the appressed biverticillate penicilli and fusiform, smooth-walled conidia. These three novelties were further confirmed by the phylogenetic analyses based on either the combined or the individual , , and internal transcribed spacer (ITS) sequences.
