Extract from Wikipedia article: Wolfiporia extensa (Peck) Ginns (syn. Poria cocos F.A.Wolf) is a fungus in the family Polyporaceae. It is a wood-decay fungus but has a subterranean growth habit. It is notable in the development of a large, long-lasting underground sclerotium that resembles a small coconut. This sclerotium called "(Chinese) Tuckahoe" or fu-ling(茯苓, pīnyīn: fúlíng), is not the same as the true tuckahoe used as Indian bread by Native Americans, which is the arrow arum, Peltandra virginica, a flowering tuberous plant in the arum family. W. extensa is also used extensively as a medicinal mushroom in Chinese medicine. Indications for use in the traditional Chinese medicine include promoting urination, to invigorate the spleen function (i.e., digestive function), and to calm the mind.

Wolfiporia extensa is a brown rot fungus that grows on the roots of trees, particularly cypress and pine. In East and Central Texas, it has been found in association with bald cypress and other conifers, where it forms mycorrhizal relationships. The fungus produces conks that are corky, woody, and effused-reflexed, often with a distinctive brown to grayish-brown color. It is commonly encountered in swampy areas and along riverbanks, where its host trees thrive.

Sclerotium "Tuckahoe" of a wood-decay fungus Wolfiporia extensa in a shallow pit dug by hogs on Caney Creek section of Lone Star Hiking Trail in Sam Houston National Forest north from Montgomery. Texas, April 10, 2020Lone Star Hiking Trail, Montgomery, TX 77356, USAIn East and Central Texas, specifically in the Sam Houston National Forest, observations of the fungus Wolfiporia extensa were made. The fungus's sclerotium, also known as "Tuckahoe", was found dug out by hogs in a pine forest on the Caney Creek section of Lone Star Hiking Trail. Remains of the fungus eaten by hogs were also observed, indicating that it is a food source for wildlife. Dissected samples of the fungus revealed its internal structure, and cross-sections of the sclerotium showed its composition. Fragments of the sclerotium were found scattered on the trail, suggesting that hogs had been actively foraging for the fungus. Close-up examinations of the dissected fungus provided detailed views of its texture and morphology. The fungus was often found in shallow pits dug by hogs, highlighting the importance of this food source for local wildlife.
