Seven New Species of Eurotiales (Ascomycota) Isolated from Tidal Flat Sediments in China.

Tidal flats have been reported to contain many microorganisms and play a critical role in maintaining biodiversity. In surveys of filamentous fungi from tidal flat sediments in China, seven new species of Eurotiales were discovered and described. Morphological characteristics and DNA sequence analyses of combined datasets of the , , and regions support their placements and recognition as new species. sp. nov. and sp. nov. belong to sections and of subgenus , and sp. nov. is a member of section of subgenus . sp. nov., sp. nov., and sp. nov. are attributed to sections and of subgenus . sp. nov. is in section . Detailed descriptions and illustrations of these novel taxa are provided. Their differences from close relatives were compared and discussed.
