Commentary: Dennis (1949) draws attention to some watercolours received at Kew (K) in 1899. Amongst these are a number from J. Lindgren, including one of Agaricus (Hebeloma) glutinosus, probably painted in 1844–1845 and according to Dennis “apparently sketches of the type collections” (HJB1000209). Collection H 6030117 (HJB14143) was collected by Karsten in September 1878 and annotated by Karsten as Hebeloma glutinosum Lindgr., so may represent original material. Based on morphological and molecular analysis this material should be referred to Cortinarius delibutus. According to Konrad & Maublanc (1924–1937), this name is a synonym of Pholiota lenta (Pers.) Singer.
