Phellinus gilvus: The Ultimate Mushroom Guide
About The Phellinus gilvus Mushroom
Phellinus gilvus is an inedible fungus. It is widespread in North America's hardwood forests. The easiest way to recognize it is the marginal area of growth is often mustard yellow contrasting nicely with the reddish brown cap.
Phellinus gilvus (Schwein.) Pat, a species of ‘Sanghuang’, belongs to the family Hymenochaetaceae in Basidomycota. Sanghuang (Phellinus spp.) has been used as Chinese traditional medicine for over 2000 years to treat various diseases such as stomachache, inflammation, and tumors. Recent investigations demonstrated that Phellinus spp. has multifunctional bioactivities, including anti-carcinogenesis, anti-inflammatory, anti-oxidative, anti-fungal, and immunomodulatory activities, as well as anti-diabetic, hepatoprotective, and neuroprotective effects.
Other names: Mustard Yellow Polypore.
