One new species and two new records of Xylarialean fungi from Andaman Islands, India

Abstract

Information on the molecular diversity of the Xylarialean fungi from the Andaman and Nicobar Islands is scarce. Xylarialean fungi are widely distributed in India, and studies revealed that two new records Hypomontagnella spongiphila and Nemania bipapillata , one new species Neoanthostomella samachedabeejae . In the phylogenetic tree generated by the ITS sequence, results were showing that three species good bootstrap support. In addition, the new species is compared with existing species in detail in the table. Microscopic and molecular studies support all these species. 82 unitunicate, apical long pedicel, smooth-walled. Ascospores 9.5–11 5–5.5 μm ( x̅ 11 × n = 25), 8-spored, hyaline to purple to brown at maturity, rarely overlapping, aseptate, straight germ slit with central globose guttulate, ellipsoid, inequilateral, obtuse end.
