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
