Velvet stem. Fruits all year. Pale, long-stemmed Inoki mushoom is cultivated form. Galerina marginata has white s.p Wickipedia says In Europe this mushroom is inedible, but it is eaten in the U.S. and Japan. It is apparently rarer than H. capnoides (edible) and H. fasiculare (inedible), though it is fairly common here in the fall. In 1993 cultures of Flammulina velutipes were flown on the Space Shuttle Columbia in order to determine how the mushrooms would handle low gravity. Like many wood-inhabiting mushrooms, Flammulina velutipes typically bends its stem near the base, then grows straight up, resulting in a cap that is more or less parallel to the ground--presumably so that spores will fall easily from the gills. Aboard the space shuttle, however, the mushrooms got confused, growing out of a simulated tree trunk at all angles. They lost their balance. 060-001
