fennae

Fenna's Winter Mushroom

Flammulina fennae is a distinct species often confused with F. velutipes but recognizable by its generally paler coloration. The cap is typically 3–8 cm wide, convex to flat, and ranges from ivory-white to pale ochre or light brown, lacking the deep orange-red tones often seen in wild F. velutipes. It grows in clusters on decaying hardwood and shares the characteristic velvety stem base of the genus. This species is notable for its slightly different temperature tolerance and microscopic features. It has shorter, broader spores (6–8 x 4–4.5 µm) compared to F. velutipes. It is cultivated by enthusiasts and has been the subject of domestication studies, particularly in Russia and Europe, where it is valued for its mild flavor and robust texture.
