Amanita luzernensis is a species of mushroom that belongs to the genus Amanita. It has a cap that ranges from 3-6 cm in diameter, typically reddish-brown to brown in color, and often features remnants of the universal veil on its surface. The gills are free, crowded, and white, while the stem is 4-7 cm long and 0.5-1.2 cm thick, with a bulbous base. In East and Central Texas, Amanita luzernensis has been found in association with oak and pine trees, typically growing in sandy or clay soils during the fall season, from September to November.

AI-generated summary of observations
Observations of the fungus Amanita luzernensis in East and Central Texas reveal distinct characteristics. The caps of grisette mushrooms, potentially Amanita luzernensis, often feature a black center, as seen on Little Lake Creek Loop Trail and Richards Loop Trail in Sam Houston National Forest. In pine forests, such as Big Creek Scenic Area, the mushrooms display similar cap features. Side views and underside observations show typical characteristics of Amanita sect. Vaginatae, with some specimens potentially being Amanita luzernensis. The dark-centered caps are a recurring feature, observed on multiple trails in Sam Houston National Forest, including Richards Loop Trail, where several grizette mushrooms were spotted. These findings suggest that Amanita luzernensis may be present in East and Central Texas, particularly in pine forests and on specific trails within Sam Houston National Forest.
