AQUATIC FUNGI OF ICELAND - PHLYCTOCHYTRIUM SCHROETER

Descriptive notes on morphological variations are given for these species of Phlyctochytrium in Iceland: P. biporosum, P. bullatum, P., equale, P. hallii, P. irregulare, P. indicum, and P. mucronatum. A Phlyctochytrium with urn-shaped sporangia possessing large discharge pores is described but is not named. Sporangial shape in this plant is nearly identical to that of Phlyctidium marinum, a Rhizophydium sp. reported by Sparrow and Koch, and two species of Chytriomyces. A second unnamed species resembling P. longicollum but having a more distinctive sporangium and a large apophysis, is reported from pine pollen. © 1969 Springer-Verlag.
