Abstract
The resting spore of Phlyctochytrium planicorne Atk. is epibiotic, and during development is similar in external morphology to the zoosporangium of the spp. Both are ovoid and have 4 plain, solid teeth forming a collorette around the apex of the thallus. During development of the resting-spore thallus, which is apparently asexual from a zoospore, a single-layered thick wall is laid down by the extramatrical portion. At maturity the resting spore is spherical or nearly so, has its own distinct, smooth wall, and lies within a light yellowish tan ornamented container probably formed from the original wall of the extramatrical portion of the producing thallus. The large eccentric globule is surrounded by a layer of smaller globules tightly appressed to its periphery. The endobiotic portion of the resting spore thallus is similar to that of the zoosporangial phase. Germination of the resting spore was not observed. An emended diagnosis of Phlyctochytrium planicorne Atk. is presented.This publication has 0 references indexed in Scilit:
