First report on Obelidium megarhizum (Chytridiaceae) from India

摘要

In the present report, Obelidium megarhizum Willoughby was isolated, described and illustrated based on morphological traits. The species is mainly recognized by the presence of conspicuous sub-apical spine or barb bearing thin-walled sporangium and relatively coarse rhizoidal system. Short description, comments, color photo, and illustration, accompanied by its comparison with other allied taxa of the genus are provided in this paper for this relatively rare species. To the best of our knowledge, this is the first generic record of O. megarhizum outside UK, USA, and Poland.
