Rõssin

Rõssin is a genus of fungi belonging to the family Rhyzangiaceae. These fungi are primarily found in soil and play a role in nutrient cycling within ecosystems. The genus was first described in 1946 by J.W.G. Lundquist. Rõssin fungi are characterized by their unique spore-bearing structures, known as sporangia, which are typically globose or subglobose. The sporangia are often borne on short stalks or directly on the mycelium. The spores themselves are usually small and smooth-walled.

The life cycle of Rõssin fungi involves the formation of sporangia, which release spores. These spores, when conditions are favorable, germinate and develop into a network of hyphae called mycelium. The mycelium is the vegetative part of the fungus and is responsible for absorbing nutrients from its environment. Reproduction can occur both asexually through spore dispersal and, in some species, sexually. While not extensively studied for specific ecological roles, Rõssin species are generally considered saprophytes, meaning they decompose organic matter. Their presence in soil contributes to the breakdown of dead plant material, releasing essential nutrients back into the soil for other organisms. Further research is ongoing to fully understand the biodiversity and ecological significance of this genus.
