Trichozoa

Trichozoa is a genus of fungi in the family Trichocomaceae. The genus contains a single species, Trichozoa sphaerospora, which was first described by mycologist John I. Pitt in 1979. The species is known to produce mycotoxins, specifically sterigmatocystin, which is a potent carcinogen.

Taxonomy

The genus Trichozoa was first described by John I. Pitt in 1979. The genus name is derived from the Greek words trichos (hair) and zoa (animal), referring to the hair-like structures present in the species. The species epithet sphaerospora refers to the spherical shape of the spores.

Description

Trichozoa sphaerospora is characterized by its production of spherical spores and hair-like structures. The spores are typically 3-5 micrometers in diameter and are produced in chains. The hair-like structures, or setae, are dark brown and can reach lengths of up to 100 micrometers.

Habitat and distribution

Trichozoa sphaerospora is a saprophytic fungus, meaning it obtains its nutrients from decaying organic matter. It has been isolated from a variety of substrates, including soil, plant material, and indoor environments. The species has a worldwide distribution.

Mycotoxin production

Trichozoa sphaerospora is known to produce the mycotoxin sterigmatocystin. Sterigmatocystin is a potent carcinogen and has been linked to liver and lung cancer in humans. The toxin is produced in the fungus's spores and can be released into the environment when the spores are disturbed.
