Linnaeus 1753 Xanthophyceae Vaucheriaceae Vaucheria GBIF Plantae Vaucheriales Xanthophyta species canalicularis      Conferva canalicularisLinnaeus,  Species Plantarum2: 1164. 1753.  "Habitat in Europae rivulis, tubulis, canalibus molendinariis." RCN: 8378.   Lectotype(Christensen in Brit. Phycol. Bull.3: 466. 1968): [icon] "  Conferva rivulorumcapillacea, densissime congestis ramulis" in Dillenius, Hist. Musc.: 21, t. 4, f. 15. 1741. - Voucher: Herb. Dillenius ( OXF).   Note:Van den Hoek ( Revis. Eur. Sp. Cladophora: 223. 1963) designated material in the Dillenius herbarium as the type but as this was not studied by Linnaeus, it cannot be original material. Christensen (in Brit. Phycol. Bull.3: 465-466. 1968) treated Dillenius'description as the type but clearly included the cited plate as part of this. As a consequence, his statement is accepted as a formal typification of the name. 2612072614 OXF
