Thermoascus is a genus of soil fungi in the family Trichocomaceae. Species in the genus are characterized by the production of heat-resistant ascospores. Thermoascus was circumscribed by German botanist Hugo Miehe in 1907.[1]

The type species, Thermoascus aurantiacus, is of research interest because it secretes heat-resistant hydrolase enzymes that could possibly be used in biotechnological applications, such as the conversion of biomass to biofuels.[2] Genetic tools have been developed to genetically edit Thermoascus aurantiacus, such as an Agrobacterium tumefaciens-mediated transformation protocol and a CRISPR-Cas9 gene editing system, which have been used to overexpress genes that correspond to production of enzymes that break down plant matter and inactivate genes.[3]

Species

  • Thermoascus aegyptiacus S. Ueda & Udagawa (1983)[4]
  • Thermoascus aurantiacus Miehe (1907)[1]
  • Thermoascus crustaceus (Apinis & Chesters) Stolk (1965)[5]
  • Thermoascus taitungiacus K.Y.Chen & Z.C.Chen (1996)[6]
  • Thermoascus thermophilus (Sopp) Arx (1970)[7]
  • Thermoascus verrucosus (Samson & Tansey) Houbraken, Frisvad & Samson (2020)
  • Thermoascus yaguchii (Samson & Tansey) Houbraken, Frisvad & Samson (2020)

Another described species, Thermoascus isatschenkoi Malchevskaya (1939),[8] is considered doubtful due to a lack of examinable material and an incomprehensive description.[9]
