The poorly known species Inocybe albomarginata Velen., apparently overlooked in the field, is described based on new fresh finds and herbarium study at PRM. A comparison with Velenovský's original diagnosis is made, the taxonomic position is evaluated, and a neotype is designated. The selected specimen (Karlštejn, 1946, leg. A. Pilát) is designated as neotype (PRM 689136), and its microcharacters are documented. It differs macroscopically by a whitish cracked margin and microscopically by specific basidia and cystidia features.
