It is found in the Russian Far East, in Mongolia, and from northwest Alaska, where it grows parasitically on lichens from the genera Cetraria and Flavocetraria.

Zhurbenko noted that although the general morphological profile of the fungus is consistent with Clypeococcum, all of the other known species of that genus have four- or eight-spored asci.

[1] Clypeococcum bisporum makes well-developed vegetative hyphae that are 2–3 μm in diameter, are olive-brown in colour, and completely penetrate the lobes of the host lichen.

These ascospores are spindle-shaped (fusiform), divided by a single septum (both resultant cells are equal in size), and typically measure 20–27 by 5–5.5 μm.

The fungus has been recorded from the arctic tundra and forest–tundra areas of the Lower Lena River region of Siberia,[1] from Renchinlkhümbe, Mongolia,[2] and from Kotzebue, Alaska.
