Ultrastructure of vegetative cells and autospores of an aerophytic strain of Vischeria stellata (Chodat ex Poulton) Pascher (Eustigmatophyceae) from Bulgaria.

Abstract

During investigation of the algal flora in the area of the Natural rock phenomenon and protected area Belogradchishki Skali (Bulgaria), an aerophytic strain of Vischeria stellata (Chodat ex Poulton) Pascher was taken in culture and analyzed by means of light (LM) and transmission electron microscopy (TEM). In the present paper some new data obtained on the architecture of vegetative cells and autospores (e.g. cell wall structure, pyrenoid development and organization) are provided as addition to the knowledge on the ultrastructure of this species.
