The fine structure of Hortaea werneckii.

Hortaea werneckii (strain CBS 107.67) was examined by light and transmission electron microscopy (TEM). Special attention was paid to the wall architecture, the septum with a simple pore apparatus, the annellidic type of collar and the nuclei. Two-celled organisms showed signs of distoseptation; nuclear events appeared to be rather synchronous in both cells. The fine structural results provided evidence of endogenous conidia development.
