New and interesting lichenicolous fungi at the Botanische Staatssammlung Munchen

Pronectria rolfiana Etayo sp. nov. is described on Solorina sp. from Austria and Germany. The new species has been confused with Xenonectriella lutescens, a species hitherto reported from one locality in Bavaria. Scutula pseudocyphellariae Etayo & Triebel is described on Pseudocyphellaria berberina and P. flavicans from southern Chile and Unguiculariopsis fasciculata Et so on Ramalina stenospora from Florida. The new combination Clypeococcum psoromatis (A. Massal.) Etayo comb. now is introduced for the common Mediterranean lichenicolous fungus hitherto named Clypeococcum epicrassum (H. Olivier) Nav.-Ros. & Cl. Roux.
