Syncephalis indica sp. n. from India S. N. Singh and A. K. Sarbhoy With 2 figures
Thirtyfive species and one variety of the genus Syncephalis have been recognized by BENJAMIN (1966). Out of these, fifteen have so far been recorded from India by various mycologists (MEHROTRA 1959; MEHROTRA and PRASAD 1964, 1965 and 1967). The authors have isolated a species of Syncephalis from Jodhpur soil during their survey of various soil fungi from India. The new isolate is characterized by its subglobose to turbinate vesicle and smaller conidia. On examination, 'it comes near to Syncephalis depressa and S. nodosa, having a branched merosporangia, but it differs in size from the conidiophores, columellae, and conidia. These divergent characters induced the authors to give a new specific name after the place of its country's origin.
