Lophocolea pilistipula Steph.,

Thouvenot, Louis & Price, Michelle J., 2020, Chiloscyphus parapilistipulus (Lophocoleaceae), a new species of liverwort from New Caledonia, with the typification of Lophocolea pilistipula, Candollea 75 (2), pp. 285-289 : 286

Lophocolea pilistipula Steph., Sp. Hepat. 6: 288. 1922.

≡ Chiloscyphus pilistipulus (Steph.) J.J. Engel & R.M. Schust in Nova Hedwigia 39: 421. 1985.

Lectotypus (designated here): NEW CALEDONIA. Prov. Sud: Île des Pins , forêt de Watchia , à la baie de Oupe, V.1909, Le Rat s.n. ( G [ G00112487 ]! ; isolecto-: REN!).

Notes. – The succinct original description of Lophocolea pilistipula corresponds to the vegetative and sexual characters observed in the fertile plants from the Île des Pins [ G00112487 ] and the illustration in Icones Hepaticarum represents the gynoecial parts of this specimen (STEPHANI, 1876–1917: tab. 5768). The fertile specimen from Île des Pins in G, seen by Stephani, is therefore designated as lectotype of Lophocolea pilistipula . A duplicate is housed in the General E.G. Paris herbarium (REN).

From a taxonomic point of view, we are adopting here the generic name Lophocolea as used in the World checklist of hornworts and liverworts ( SÖDERSTRÖM et al., 2016). The name Chiloscyphus pilistipulus was created by ENGEL & SCHUSTER (1985) according to their broad concept of the genus Chiloscyphus which includes Lophocolea as a subgenus. Recent phylogenetic studies indicate that they represent two distinct genera ( SÖDERSTRÖM et al., 2013; PATZAK et al., 2016).
