Fine Structure of the Young Vegetative Hyphae of Pythium debaryanum

Abstract

The fine structure of Pythium debaryanum Hesse differs from that of Rhizopus species and some other fungi in the abundant regularly distributed endoplasmic reticulum, the presence of typical Golgi bodies and the irregularly tubular structure of the cristae mitochondriales. Some of these characters resemble those of some algae and the liverwort Anthoceros and the significance of this is discussed. Typical lomasomes are present.
