Five new records of Annulohypoxylon spp. (Hypoxylaceae) from India

ABSTRACT

Species of Annulohypoxylon are saprotrophic fungi growing predominantly on dead shoots of dicots. They are also known to produce a diverse range of secondary metabolites, including some bioactive compounds. During a survey conducted in tropical, sub-tropical and temperate forests of Arunachal Pradesh (Northeast India) that lies within the Himalayan biodiversity hotspot, seven species of Annulohypoxylon (Hypoxylaceae) were collected and identified. Of these, five are new records to India (A. leptascum, A. microbovei, A. nitens, A. subeffusum, A. viridistratum) while A. subeffusum is a new report from Southeast Asia. The two remaining species (A. stygium, A. truncatum) were previously reported from India. All seven species are described, illustrated and discussed based on morphology.
