Knudsen, K., Kocourková, J., Hodková, E. & Schiefelbein, U. 2021. A new species of Myriospora (Acarosporaceae) and a report of Myriospora rufescens from Central Europe. – Herzogia 34: 327–338.

Myriospora bullata is described from Germany. It is similar to M. scabrida in having apothecia in a parathecial ring but differs in becoming bullate, in often being orange, and in being a lichenicolous lichen. It is probably restricted to copper-rich rock. Myriospora himalayensis is not considered a member of the genus but a regional lineage in either Acarospora or Sarcogyne. Myriospora rufescens is reported new for the Czech Republic.
