Myxomycetes of Maharashtra: two new species of Diderma Pers

Abstract

The present paper provides the description and illustrations of two new species of Diderma (D. non-columellata sp. nov. and D. physarinum sp. nov.) that are characterized by the absence of columella in the first instance and the presence of a large columella bearing a number of peg-like protuberances running through the sporangial cavity up to the peridium in the second instance. The latter condition is similar to what is found in the genus Physarina respectively.
