Sulphurina

Sulphurina is a genus of fungi belonging to the family Physalacriaceae. These fungi are characterized by their typically small, often yellow to orange fruiting bodies. The name "Sulphurina" likely derives from the sulfurous or yellowish coloration observed in many species within this genus.

The fruiting bodies of Sulphurina species are generally agaricoid, meaning they possess a cap, gills, and a stipe. The caps can vary in shape and size, often being convex to broadly convex. The gills are usually attached to the stipe and can be adnate or sinuate. The stipe is typically slender and can be centrally or eccentrically attached to the cap.

Sulphurina species are saprobic, meaning they obtain nutrients from dead organic matter. They are commonly found growing on decaying wood, leaf litter, or other plant debris in terrestrial environments. Their distribution is widespread, with various species reported from temperate and tropical regions across the globe.

Distinguishing between species within the genus Sulphurina often relies on microscopic features, such as the shape and size of spores, basidia, and cystidia. While some species may have distinctive macroscopic characteristics, detailed examination is frequently required for accurate identification. Research into the phylogeny and taxonomy of Sulphurina continues to evolve, with new species being described and existing classifications being refined based on molecular data.
