Russula albidicremea is a small to medium-sized mushroom with a white to cream-colored cap, typically 2-5 cm in diameter, and a white stem. It has a fruity or sweet odor and taste. In East and Central Texas, it is commonly found in association with oak trees, particularly live oak and post oak, from June to October. The fungus grows solitary or in small groups on the ground in wooded areas, often in rich soil with abundant leaf litter. Its spores are white, and the gills are crowded and free from the stem.

Spores of brittlegill mushroom Russula albidicremea collected near Pole Creek on North Wilderness Trail of Little Lake Creek Wilderness in Sam Houston National Forest north from Montgomery. Texas, August 31, 2022Observations of the fungus Russula albidicremea in East and Central Texas reveal that it grows in pine forests, often near roads or trails. The mushroom was found on multiple occasions in Sam Houston National Forest, particularly near Little Lake Creek Wilderness and along Forest Service Road 231. It typically appears as a large, white brittlegill mushroom, with some specimens reaching maturity and displaying characteristic gills and spores. The fungus was observed in various stages of growth, from mature to dried, and its spores were collected and examined under a microscope. Notably, the taste of the mushroom was reported as not bitter, which is consistent with some species of Russula. The observations span several months, including June, August, and October, suggesting that the fungus may have a relatively long fruiting season in this region.
