Synonym: Botryobasidium robustior.
Botryobasidium robustius is a species of fungus that belongs to the family Botryobasidiaceae. It is characterized by its effused-reflexed to resupinate basidiocarps, smooth to tuberculate hymenial surface, and subglobose to broadly ellipsoid basidiospores. In East and Central Texas, B. robustius has been found on various substrates including decaying wood, particularly hardwoods such as oak and maple, as well as on coniferous trees like pine and cedar. The fungus typically grows in shaded, humid environments, often near streams or rivers, and is commonly associated with other fungi and microorganisms that decompose organic matter.

Spores of corticioid fungus Botryobasidium robustius or may be B. aureum (from the same oak as common poria), collected on Kiwanis Nature Trail. College Station, Texas, May 1, 2023Observations of the fungus Botryobasidium robustius in East and Central Texas reveal its presence on various types of decaying wood, including logs, oak, and pine. The fungus was found on the underside of logs, rotting wood, and fallen trees in Sam Houston National Forest and Kiwanis Nature Trail. It exhibited a range of textures, from fluffy to crust-like, and was often accompanied by other fungi, such as polypore species. Microscopic examination revealed the presence of spores, hyphae, and conidiophores. The fungus was observed on multiple occasions between 2019 and 2023, suggesting its widespread distribution in the region. Its hosts included oak and pine, with some observations noting the presence of other fungi, such as common poria, on the same substrate.
