Jarvis, Charlie, 2007, Chapter 7: Linnaean Plant Names and their Types (part L), Order out of Chaos. Linnaean Plant Types and their Types, London: Linnaean Society of London in association with the Natural History Museum, pp. 610-650 : 629

Lichen proboscideus Linnaeus, Species Plantarum 2: 1150. 1753, nom. cons.

"Habitat in Suecia." RCN: 8226.

Conserved type ( Jørgensen & al. in Taxon 43: 653. 1994): Sweden. Uppland, Boo, Värmdö, Skepparholmen, 1906, Malme in Lich. Suec. Exsicc. No. 56 (UPS).

Current name: Umbilicaria proboscidea (L.) Schrad. (Umbiliculariaceae).

Note: See discussion by Jørgensen & al. (in Bot. J. Linn. Soc. 115: 340-341, 379, f. 48. 1994), who conclude that the holotype is 1273.204 (LINN), a collection belonging to Umbilicaria cylindrica (L.) Delise ex Duby. They successfully proposed the name for conservation with a conserved type.
