Sparrow , however, had earlier located and photographed the species from a packet labeled “Chytridium olla A. Br. Oedogonium Landsboroughii, Freiburg in B. legit. A. Braun” in the Institute de Botanique at Strasbourg. See: F.K. Sparrow “The type of Chytridium olla A. Braun”. Taxon 22:583–586. 1973.
