The genus is solely known from the Lower Cretaceous, Upper Albian stage (about 100 Ma), Burmese amber deposits in Myanmar.

[4] AB-368 was collected from one of the amber mines in the Hukawng Valley area southwest of Maingkhwan, Kachin Region, Northern Myanmar.

[1] It was first studied by a pair of researchers led by Dr George Poinar from Oregon State University who worked with Ron Buckley.

The fossil shows that this type of fungal parasitic relationship had been established by the Albian, 100 million years ago.

[1] An earlier instance of mycoparasitism is known from the extinct species Palaeoserenomyces allenbyensis[1] and Cryptodidymosphaerites princetonensis[2] described in 1998 from cherts found in British Columbia, Canada.

The pileus is 2.2 millimetres (0.087 in) in diameter and possesses a convex shape with the flesh a bluish gray color and hairy.

[1] The combined distinguishable characters of Entropezites were not enough for Poinar and Buckley to place the genus further than Hypocreales incertae sedis.
