The species (or when divided into subspecies, its autonymous subspecies) has been treated as "Galanthus nivalis" subsp. "reginae-olgae". Other regularly used synonyms include "G. olgae" and "G. corcyrensis". The name "Galanthus corcyrensis" has been particularly used for plants that flower in the autumn with the leaves rather than before them.

Chlamydomonas nivalis temperatures rise above 30 °C. It is a true snow alga because it performs better in low temperatures than warm temperatures. Due to "C. nivalis"’ ability to perform photosynthesis well from cold to moderate temperatures, this species is considered a cryotolerant mesophile rather than a cryophile. This organism is also very resilient as they can also survive in warm soil for weeks. They can also tolerate dryness and room temperature for as long as 6 months. Fungi, worms, bacteria, and viruses have been found to associate with or live in the same environment as "C. nivalis". Encapsulated rod-shaped gram-negative bacteria
