Abstract

The nuclear cycles of four species of strictly anaerobic rumen fungi (Neocallimastix frontalis, Piromonas communis, Neocallimastix joyonii, andSphaeromonas communis) were compared by fluorescence microscopy. The existence of two types of sporangium development and thalli was confirmed in this study. The first type involved monocentric species fitted with an endogenously developing single sporangium and with rhizoids, such asN. frontalis, P. communis, andS. communis, characterized by the presence of rhizoid-like vesicles. The second type concerned polycentric species with an exogenous sporangium development such asN. joyonii. This species is characterized by a rhizomycelium and “gamma particle-like bodies” within the zoospore.
