Byssocorticium atrovirens is a crust fungus that grows on decaying wood, characterized by its dark green to blackish-brown color and velvety texture. In East and Central Texas, it has been found on fallen logs and stumps in wooded areas, particularly in moist environments such as along streams and rivers. The fungus typically fruits in the spring and fall, producing small, rounded conks that are often densely packed and fused together. It is a relatively common species in the region, but can be overlooked due to its small size and tendency to grow in shaded, humid areas.
Observations of Byssocorticium atrovirens in East and Central Texas reveal that the fungus grows in shaded, moist environments. It was found under a pine log in Warren, Texas, on November 23, 2019, and under a log in Big Creek Scenic Area of Sam Houston National Forest in Shepherd, Texas, on January 19, 2020. The fungus exhibits a powdery blue corticioid appearance, suggesting it thrives in humid conditions with limited sunlight. Both observations were made during the cooler months, indicating that Byssocorticium atrovirens may be more active or visible during this time. The similar habitats and growth patterns observed in these two locations suggest that the fungus may have specific ecological preferences in East and Central Texas. These findings provide insight into the environmental conditions that support the growth of Byssocorticium atrovireens in this region.
