Varicellaria carneonivea is lichenized withAsterochloris phycobiontica, a new member of theChlorococcales. In the free-living state this species reproduces by zoo- and aplanospores; autospores are lacking. Sporangia develop an internal local thickening of the wall, which marks the later aperture. A group of dictyosomes apparently contributes to the formation of this thickening. Secondary carotenoids dissolved in droplets or irregular masses of oil are deposited around and within the pyrenoid. 相似文献

The phycobiont ofCatolechia wahlenbergii belongs to a new genus of theChlorococcales. It has mostly ellipsoidal, more rarely spherical cells with one bilobate through-shaped chloroplast and in general alveolar cytoplasm. Reproduction occurs by 2 or 4 autospores as well as by 16 or 32 motionless, small rodlike spores, which are formed and released in the same way as zoospores. They are aplanospores, and their formation apparently is fixed genetically, and not modificatorily, as in other species. 相似文献
