Tulasnella violea is a species of fungus that forms mycorrhizal associations with orchids. In East and Central Texas, it has been found to associate with the coralroot orchid (Corallorhiza odontorhiza) and other terrestrial orchids. The fungus produces thin, violet-colored hyphae and has been isolated from orchid roots in woodland habitats, particularly in areas with rich soil and dense tree cover. It plays a crucial role in the nutrition of its orchid hosts, providing essential nutrients in exchange for carbohydrates.

Tissues and spores of resupinate polypore mushroom with pinkish fungus Tulasnella violea(?) (in KOH) collected on Stubblefield section of Lone Star hiking trail in Sam Houston National Forest. Texas, April 11, 2023Observations of the fungus Tulasnella violea in East and Central Texas reveal its presence on old polypore mushrooms. In Lick Creek Park, College Station, it was found on mushrooms eaten by worms in December 2019. Similar observations were made in Sam Houston National Forest, where it was discovered under a burned log on the Stubblefield section of Lone Star hiking trail in April 2023. Microscopic examination (x10, x40, x100 objectives) of collected tissues revealed the presence of pinkish fungus, likely Tulasnella violea. The fungus was found to be associated with resupinate polypore mushrooms, and its spores were observed under a microscope. These observations suggest that Tulasnella violea is present in various locations in East and Central Texas, often growing on decaying fungi in forest environments. Its distinctive pinkish coloration can aid in identification.
