Tricholoma sulphurescens is a medium-sized mushroom with a yellowish-brown to greenish-yellow cap, often with a metallic sheen, and white to yellowish gills. It has a strong, unpleasant odor, resembling sulfur or coal gas. In East and Central Texas, it typically fruits from summer to fall, often in association with oak trees, particularly live oak and post oak, in woodland areas and along roadsides. The stipe is usually yellowish to brownish, staining reddish-brown when bruised. This species can be found in a variety of habitats, including wooded slopes, ravines, and floodplains, where oak trees are dominant.

AI-generated summary of observations

In East and Central Texas, observations of the fungus Tricholoma sulphurescens were made on Sand Branch Loop Trail in Sam Houston National Forest near Montgomery. The mushrooms were found growing near the trail in a pine forest on January 20, 2021. They had distinctive characteristics, with the underside showing a specific pattern. A cross-section of the mushroom revealed its internal structure. Additionally, an upturned mushroom was observed, providing further insight into its morphology. The sightings suggest that Tricholoma sulphurescens can thrive in the pine forests of East and Central Texas, particularly during the winter months, as evidenced by the January observation. The specific location and timing of these observations contribute to a better understanding of the habitat and seasonal patterns of this fungus species in the region. Further study is needed to confirm the identity and distribution of Tricholoma sulphurescens.
