Knudsen, Kerry & Jana Kocourková. A study of lichenicolous species of Polysporina (Acarosporaceae). Mycotaxon 105: 149-164. 2008.

ABSTRACT: Three lichenicolous species of Polysporina are recognized: Polysporina arenacea, P. pusilla, and P. subfuscescens. Polysporina lapponica is found to be a misapplied name to P. subfuscescens. The new combinations P. arenacea, P. subfuscescens, and Sarcogyne lapponica are made. Sarcogyne lapponica is reported from Norway, Sweden and Switzerland. A neotype is selected for Sarcogyne dubia. Polysporina pusilla is reported new for Asia (Iran, Turkey) and North America (western North America).
