Abstract: © 2018, German Mycological Society and Springer-Verlag GmbH Germany, part of Springer Nature. Fungi play a vital role as decomposers in mangrove ecosystems. A new ascomycete species, Acuminatispora palmarum, inhabiting decayed petioles and rachides of palms in mangrove habitats, is introduced in this paper based on morphological and phylogenetic evidence. Phylogenetic relationships of related taxa were inferred from combined LSU, SSU, TEF1α, and RPB2 sequence data, and the analyses indicate that A. palmarum could be recognized as a distinct group in Pleosporales, but its familial placement needs to be further resolved. The morphological characters of this new taxon are also different from other members in Pleosporales by its deeply immersed ascomata, long pedicellate asci, and biseriate to triseriate, 1-(rarely 3) septate, brown, fusiform ascospores with acute or narrowly pointed ending cells. Acuminatispora gen. nov. (Pleosporales, incertae sedis) is therefore established to accommodate the new taxon A. palmarum. Furthermore, phylogenetic relationships of Acrocordiopsis and Caryospora are discussed with a consideration of morphological observations.
