Trichoderma sulphureum is a species of fungus in the family Hypocreaceae, order Hypocreales, class Sordariomycetes, phylum Ascomycota. It is characterized by its greenish-yellow to sulphur-yellow conidial masses and ellipsoidal to globose conidia. In East and Central Texas, Trichoderma sulphureum has been found in a variety of habitats, including soil, decaying wood, and plant debris, with reports from counties such as Brazos, Grimes, and McLennan. It is typically isolated from summer to fall, with optimal growth at temperatures between 25-30°C.
Observations of Trichoderma sulphureum in East and Central Texas revealed the fungus growing on a wet piece of wood in Hensel Park, College Station, on February 28, 2018. The fungus was also found in the same location on the same date, suggesting it may thrive in the park's environment. The presence of Trichoderma sulphureum in this area indicates that it can tolerate the region's climate and substrate conditions. The fact that it was found on a wet piece of wood suggests that moisture may play a role in its growth and development. Further observations are needed to fully understand the distribution and habits of Trichoderma sulphureum in East and Central Texas, but these initial findings provide valuable insights into its ecology. Additional data could help determine if this fungus is widespread in the region or limited to specific areas like Hensel Park.
