Nyl., Notiser ur Saellskapets pro Fauna et Flora Fennica Foerhandlingar , 5: 276, 1861 Verrucaria rupestris var. integra Nyl., Actes Soc. Linn. Bordeaux, 21: 183, 1856. Basionym. Type. Not in H-NYL, protologue: "in Gallia passim (Ejus statum ochraceo-tinctum, E Cebennis inferioribus in hb. Mougeot vidi)". Notes. The type material has not been located (possibly in Paris). Nylander had a very wide circumscription for V. integra . Specimens identified by Nylander as V. integra in H-NYL represent several species of Verrucaria . Thus, the identity of V. integra cannot be solved without studying the type material. Two old records of this species have been reported from Finland (Vainio 1921), but these specimens belong to V. viridula . Based on Vainio's interpretation of V. integra , the species may be conspecific with V. viridula .
