" on the underside of the cap. This mushroom is found throughout the world. It is found in the wild on decaying trees after rainy seasons followed by dry spells where the mushrooms are naturally collected. It is known for its high medicinal value and aromatic taste profile. It has recently attracted the medicinal industry for its immunomodulatory, antifungal, antineoplastic and antiviral activities that are higher than those of any other glucan complex carbohydrate.

Edibility

The species was regarded as nonpoisonous by Orson K. Jr. and Hope H. Miller, who considered it to be inedible due to its smallness and toughness. There is evidence that it may be a common cause of fungal infections and related diseases, most commonly that of the lungs. They have also been reported to cause
