BM 3480 / Badhamia alpina / G. Lister/ E. Switzerland / BM001089968 [sheet label dated 25 NOV. 1914: “BM 3480/ Badhamia alpina G. Lister / in Journ. Bot. Lii.p.99 (1914)/ On stalks of Cirsium spinosissimum / Arosa, Graubunden, July 1913, G. Lister”, and a revised label “ TYPE SPECIMEM/ DET: D.T.

NOTES: In describing this species G. Lister (1914: 99) wrote that the material was “found in some abundance on and inside hollow scapes of Cirsium spinosissimum and Senecio alpinus , above Arosa, 7000 ft. alt.” The only material in BM collected by G.Lister is BM 3480, and the box makes specific reference to the publication, so it is designated here as the lectotype. The two slides have the same data are from the same sample. One of them makes reference to the notebook XXXIV: 36, where the material “Arosa 7.13” is illustrated and commented on, but with several dates, thus “found on and within the hollow scape of Cirsium spinosissimum & Senecio cordifolium = S. alpinus , on July 5 th,

6 th & 14 th, near the Mittlerhutte [Arosa]”. In the same notes other material received earlier is mentioned, from canton Graubunden (Trimmis and Furstenalp), collected by Prof. A. Volkart in June 1903 and June 1904, from Ste. Croix in the Jura Mts., collected by Ch. Meylan and from Areskutan, Jämtland, Sweden, collected by Dr. R.E. Fries in August 1905, that may be syntypes of the species but no material corresponding to these data was found in BM. Kowalski revised BM 3480 in July 1971. Martin & Alexopoulos (1969) consider this a synonym of B. foliicola , but other authors ( Poulain et al. 2011) maintain it as a separate species.
