摘要

A new species of Astrosphaeriella was collected from submerged wood in Thailand. Identification based on morphological characters and a comparison of sequence data from partial regions of the 28 large subunit ribosomal (LSU) RNA and 18 small subunit ribosomal (SSU) RNA genes supported its novel status. Astrosphaeriella thailandensis, sp. nov., is described and illustrated. It is distinguished from other similar species in size and ornamentation of ascospores.
