Pholiota alnicola (Fries) Singer is a widely distributed saprophyte found on hardwoods and conifers throughout North America. This species is a bit of an outcast compared to the majority of Pholiota, belonging to the subgenus Flammula. Unlike most others, P. alnicola lacks the characteristic pleurocystidia and scales on its cap. The dull yellow mushroom has a convex cap measuring about 5 cm in diameter and has a stipe 4-8 cm long. The gills are a lighter yellow and attach to the stipe. The spores of P. alnicola are a dark rusty brown measuring 9×4 micrometers. Interestingly, its mycelium has high levels of antioxidant activity and its potential for dietary supplement production is being researched.
