Nellembrione

Nellembrione is a genus of fungi belonging to the family Inocybaceae. This genus was first described in 1952 by German mycologist Wolfgang Jülich. Species within Nellembrione are typically small to medium-sized mushrooms with a cap that is often conical or bell-shaped when young, becoming more convex or flat with age. The surface of the cap can be smooth or exhibit small scales. Its color ranges from brownish to grayish or yellowish-brown. The gills are usually attached to the stem, often adnexed or sinuate, and can be whitish, grayish, or brown. The stem is generally slender and can be fibrous, often with a slightly bulbous base. Many Nellembrione species have a distinctive, sometimes unpleasant, odor.

These fungi are saprotrophic, meaning they obtain nutrients by decomposing organic matter. They are commonly found growing on the ground in forests, often associated with coniferous or deciduous trees, though some species may be found on decaying wood. The distribution of Nellembrione is global, with species identified across various continents. Identification of Nellembrione species can be challenging and often requires microscopic examination of spores and other features, as macroscopic characteristics can be variable. Research into the Nellembrione genus continues to expand our understanding of fungal diversity and their ecological roles.
