Riccardia regnellii (Ångstr.) K.G.Hell, Bol. Univ. São Paulo, Bot. 25: 110, 1969 ( Hell 1969).

Basionym:— Pseudoneura regnellii Ångstr., Öfvers. Kongl. Vetensk. View in CoL -Akad. Förh. 33, 7: 90 1876 [1877] ( Ångström 1877).

The identity of Lopholejeunea nigricans (Lindenb.) Schiffn. β monstrosa (Nees) Schiffn.

Lopholejeunea nigricans (Lindenb. in Gottsche et al. 1845: 306) Schiffner (1893: 293) ( Lejeunea nigricans Lindenb. ) is a widespread pantropical species ( Zhu & Gradstein 2005). In his original description of Lejeunea nigricans, Lindenberg ( Gottsche et al. 1845) mentioned the existence of a small, densely branched form of the species described by Nees (1830) as Jungermannia applanata β monstrosa Nees. Whereas Lopholejeunea nigricans has been studied by many authors, its β monstrosa has not been given attention since the original description. My study of the holotype material of Jungermannia applanata β monstrosa in the liverwort herbarium of C. G. Nees von Esenbeck (STR-Nees) revealed that the plant is identical to Lopholejeunea zollingeri ( Stephani 1890) Schiffner (1898) , a widespread Southeast Asian species. The new synonymy is as follows:
