Extract from Wikipedia article: Helicobasidium purpureum is a fungal plant pathogen which causes violet root rot in a number of susceptible plant hosts. It is synonymous with Helicobasidium brebissonii (Desm.) Donk. It is the teleomorph of Tuberculina persicina which is its mycoparasitic anamorph.

Helicobasidium purpureum is a violet to purple-colored fungus that grows as a crust or mat on the surface of soil, decaying wood, and other organic matter. In East and Central Texas, it typically fruits in the spring and summer months, often forming large, sprawling patches on disturbed ground, such as roadsides, trails, and areas with rich soil. The fungus can also be found growing on roots and lower stems of plants, particularly grasses and forbs. It is a relatively common sight in the region's woodland edges, prairies, and urban landscapes.
Orange Berry Rust fungus Gymnoconia nitens on blackberry, with purple spots to the right caused by asexual stage of Helicobasidium purpureum (violet root rot, Tuberculina persicina), in Falls on the Brazos Park. Marlin, Texas, March 16, 2018
644 FM 712, Marlin, TX 76661, USAIn East and Central Texas, observations of Helicobasidium purpureum have been noted. The fungus was found to infect blackberry plants, causing violet root rot, also known as Tuberculina persicina. In Falls on the Brazos Park, Marlin, Texas, the fungus was observed alongside Orange Berry Rust fungus Gymnoconia nitens on March 16, 2018. The asexual stage of Helicobasidium purpureum produced purple spots on the blackberry plant, distinguishable from the orange rust caused by Gymnoconia nitens. This co-occurrence suggests that Helicobasidium purpureum is present in the region and can infect plants simultaneously with other fungal species. The observation highlights the presence of this fungus in East and Central Texas, specifically in Falls County, where it may pose a threat to plant health. Further observations are necessary to understand its distribution and impact on local flora.
