Uncinocarpus uncinatus is a species of microfungi that grows on dung and other keratinous materials such as bone.

The species was first described by Randolph S. Currah in 1985; synonyms include Myxotrichum uncinatum and Gymnoascus uncinatus.

In culture, colonies of U. uncinatus are yellow to orange-brown to red-brown in colour, growing paler towards the margin.

Like other members of Uncinocarpus, it develops hooked and occasionally spiralling (uncinate) appendages which typically, but not always, possess spore-bearing structures (gymnothecia).

The appendages of U. uncinatus are thick and wide to the distal end, unlike that of U. reesii, which taper to a point.
