Summary
The fine structure of the filamentous and mycelial cell ofEndomycopsis fibuliger grown on the agar medium and fixed in osmium tetroxide is described. The cell wall is relatively thick. Of particular interest is the occurrence of numerous vesicles underside of the cell wall proper. They have become dilated frequently at the cell surface, probably as a result of the amylase secretion. The wall presumably is penetrated by plasmodesmata. The plasmodesmata and the intercellular connections are associated with the endoplasmic reticulum. The cytoplasmic matrix is generally granular and contains nonmembrane-limited patches of lipoid.
Mitochondria are numerous and variable in shape, and have been observed in different stages of development. The mitochondria profiles are delimited from the surrounding cytoplasm by single or sometimes double electron-dense lines.
The double dark lines of a unit membrane at the nuclear surface are not always clear.
