Gyrodontium sacchari is a rare fungus that grows on soil and decaying organic matter. In East and Central Texas, it has been found in wooded areas, particularly under hardwood trees and in association with oak wilt. The fungus produces distinctive fan-shaped or semicircular fruiting bodies that are typically 2-6 cm in diameter, with a wavy or lobed margin and a velvety to hairy surface. The spines or teeth on the underside of the fruiting body are characteristic of the species. Gyrodontium sacchari is considered a relatively rare find in Texas, but it can be locally common in certain areas, particularly during the summer and fall months when humidity is high.

Cross section of hydnoid mushroom Gyrodontium sacchari (Coniophoraceae) slowly turning blue on Stubblefield section of Lone Star hiking trail north from Trailhead No. 6 in Sam Houston National Forest. Texas, July 31, 2020Lone Star Hiking Trail, Montgomery, TX 77356, USAObservations of the fungus Gyrodontium sacchari in East and Central Texas reveal its distinctive characteristics. The tooth mushroom was found on a piece of wood in soil disturbed by hogs on the Stubblefield section of Lone Star hiking trail. Its olive-green tooth surface and underside were notable features. The hydnoid mushroom was observed with a piece of woody substrate, and its cap was also documented. A cross-section of the mushroom showed it slowly turning blue. These observations suggest that Gyrodontium sacchari thrives in disturbed soil environments, such as those created by hog activity, and exhibits unique coloration and morphology. The fungus's presence on decaying wood highlights its role in decomposition processes in East and Central Texas ecosystems. Overall, these findings provide insight into the habits and characteristics of Gyrodontium sacchari in this region.
