Thamnidium anomalum Thamnidium ctenidium Thamnidium elegans Thamnidium is a genus of fungi belonging to the family Mucoraceae.

[1] The genus was circumscribed in 1809 by Johann Heinrich Friedrich Link.

[1] Thamnidium molds are key participants in the aging process for dry aged beef, producing protease and collagenase enzymes that naturally tenderize the meat.

[2] Thamnidium forms pale grey patches of mold called 'whiskers' on fatty areas of a carcass or cut during the aging process.

[3] The genus has also been implicated in the spoiling of meat in cold storage, alongside other fungal genera such as Acremonium, Mucor and Rhizopus.
