Clypeococcum bisporum is a species of lichenicolous (lichen-eating) fungus in the family Polycoccaceae. 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.
Clypeococcum bisporum was scientifically described as new to science in 2009 by Russian lichenologist Mikhail Zhurbenko. The type specimen was collected by the author from the Lena river delta on Stolb Island (Yakutiya, Russia); there, the fungus was found growing parasitically on the lichen Flavocetraria cucullata, which itself was growing on the ground in tundra. The species epithet bisporum refers to its two-spored asci. 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]
