We have studied and tried to clarify the application of names of all the lichenicolous fungi described by Carlos Spegazzinii. Several of these names have not previously been treated by mycologists currently specializing in lichenicolous fungi. Verruculina gen. nov. is introduced with V. sigmatospora (Speg.) Etayo (syn. Metanectria sigmatospora) as type, and the new combination Scutula nephromatis (Speg.) Etayo (syn. Patellea nephromatis) is made. Material of several species, Diplosporium caudatum (on Punctelia), Pleurotus lichenicolus (on Usnea), Pyrenopeziza lichenicola (on Flavoparmelia), Selenosporium lichenicola (on Candelaria) and Vermiculariella lichenicolum (on Physcia and Peltigera), could not be located in Spegazzini’s collections in La Plata (LPS), therefore these names remain to be clarified.
