Galanthus reginae-olgae three smaller inner tepals, white with variable green markings near the tips. The outer tepals are about 15–35 cm long, the inner ones 9–12 mm long. Populations of "Galanthus reginae-olgae" that flower at different times, with or without the leaves being fully developed, have been described as separate species or subspecies. Those described as "G. reginae-olgae" subsp. "reginae-olgae" flower in the autumn, either before the leaves develop or with the leaves. Those described as "G. reginae-olgae" subsp. "vernalis" flower in late winter or early spring, with the leaves. "Galanthus reginae-olgae" was first described in 1876 by Theodoros G. Orphanides. The
Chlamydomonas nivalis food source. Infections of "C. nivalis" cells by chytrids, "Chytridium chlamydococci", filamentous fungi, and "Selenotila nivalis" have also been observed. As winter approaches, the cells will approach the last stage of their life cycle. The orange cells mature into red cysts, the form in which it will remain for the remainder and longest portion of its life cycle. Cells at this stage are most resistant to harsh environmental conditions. Inorganic and organic materials such as bacteria, fungi, and dust particles coat the mucilage layer of the cell wall. The inorganic impurities were found to be rich in silicon, iron, and
