Atheliachaete sanguinea is a species of fungus that belongs to the family Atheliaceae. It is characterized by its resupinate to effused-reflexed habit, with a smooth to velutinous hymenial surface and acanthophysis-like hyphal structures. In East and Central Texas, it has been found growing on decaying wood, particularly on hardwoods such as oak and maple, in moist environments like stream banks and woodland edges. The fungus produces small, cylindrical basidiospores that are 5-7 μm in length, and its fruiting bodies are typically reddish-brown to blood-red in color, with a wavy or lobed margin.

Lone Star Hiking Trail, Montgomery, TX 77356, USAObservations of the fungus Atheliachaete sanguinea in East and Central Texas reveal distinctive characteristics. On April 22, 2018, at the Caney Creek section of Lone Star Hiking Trail in Sam Houston National Forest near Huntsville, Texas, the fungus was found to cause a vibrant red coloration on wood. This phenomenon was noted specifically on trees in this region, suggesting that Atheliachaete sanguinea has a preference for certain hosts or environments. The fungus's ability to impart a deep red hue to the wood is a notable feature, potentially aiding in its identification and differentiation from other fungal species. Further observations in East and Central Texas may uncover additional insights into the habitat preferences and distribution of Atheliachaete sanguinea. The specific conditions and tree species affected by the fungus in this region warrant further investigation to fully understand its ecological role.
