New conidial fungi from Andaman Islands, India

Abstract

Four new species of litter-inhabiting Hyphomycetes are described from the forests of Middle Andaman Island, India. These are (1) Argopencoma indiraei sp.nov. characterized by catenate, globose, hyaline blastic conidia developing on flexuous conidiophores with discrete conidiogenous cells, (2) Virgatospora natarajensis sp.nov. producing fusiform, non-septate, olive green to dark brown, phialidic conidia with longitudinal surface ridges on erect synnematous conidiomata, both isolated from decaying leaves of Calamus thwaitesii; (3) Phialocephala vittalensis sp, nov with catenate, I-septate, pale brown phialidic conidia developing on apically branched conidiophores and (4) Stratiphoromyces raghukumarensis sp.nov. producing fusiform, curved, I-septate, phialidic conidia on percurrently regenerating conidiophores, isolated from fallen leaves of Caryota urens.
