Strobilurus conigenoides is a small to medium-sized mushroom with a conic to bell-shaped cap that ranges in color from yellow-brown to reddish-brown. It has a slender stem and gills that are narrowly attached to the stem. In East and Central Texas, this fungus typically fruits in the spring, often growing in clusters on decaying conifer logs, particularly those of eastern red cedar and other junipers. The caps are usually 1-3 cm in diameter and the stems are up to 6 cm long. It is a relatively rare find in the region, but can be encountered in areas with abundant conifer debris.
