The replacement names for Pinnularia species (Bacillariophyta). R. M. Gogorev. — Заменяющие названия для видов рода Pinnularia (Bacillariophyta). Р. М. Гогорев.
Pinnularia rabenhorstii Hilse (1860) was described from Schlesien, Germany near Reichenbach. The later homonym of this name was published by Krammer (2000), who transferred Navicula rabenhorstii Grunow into the genus Pinnularia Ehrenb.
Also, Kramer recognized three varieties within P. rabenhorstii, which were then raised to specific rank (Kulikovskiy et al, 2010). Two of the varieties, P. rabenhorstii var. elegans (Hust.) Krammer and P. rabenhorstii var. cuneata Krammer et Lange-Bert., received legitimate replacement names (P boreoelegans Kulikovskiy, Lange-Bertalot et Metzeltin and P. neocuneata Kulikovskiy, Lange-Bertalot et Metzeltin, respectively), while the third one,

P. rabenhorstii var. franconica Krammer, was given the combination P franconica (Kram-mer) Kulikovskiy, Lange-Bert. et Metzeltin, which is illegitimate as a later homonym of P franconica Mayer (1946).
The replacement names for these two homonyms are published below.

New combination Nyholmiella furcata (Orthotrichaceae, Bryophyta). T. N. Otnyukova. — Новая комбинация Nyholmiella furcata (Orthotrichaceae, Bryophyta). Т. Н. Отнюкова.
Holmen et Warncke found out that Orthotrichum gymnostomum Bruch. ex Brid. and O. obtusifolium Brid. belonged to a separate genus Nyholmiella Holmen et Warncke (Dam-sholt et al., 1969), and published appropriate new combinations. Later, O. furcatum Otnyukova (abbreviated in the protologue as T. Otn.) with branched papillae was described from the Tyva Republic (South Siberia, Russia) (Otnyukova, 2001). In «Moss Flora of Russia» (Ignatov et al., 2017) this species was synonymized with Nyholmiella obtusifolia because of ramified papillae in the latter, too. These species, however, differ in the shape of the papillae, deeply (2)3—5-divided in O. furcatum, and simple or sometimes shallowly 2-separated in N. obtusifolia. O. furcatum has gemmae and therefore also belongs to the genus Nyholmiel-la. The new combination is published here.

Lectotypification of Hygrolejeunea alaskana R. M. Schust. et Steere (Lejeuneaceae, Marchantiophyta). I. V. Sokolova, A. D. Potemkin. — Лектотипификация Hygrolejeunea alaskana R. M. Schust. et Steere (Lejeuneaceae, Marchantiophyta). И. В. Соколова, А. Д. Потемкин.
The name Hygrolejeunea alaskana R. M. Schust. et Steere (Schuster, Steere, 1958) was validly published with indication of one gathering as the type: «Driftwood Camp, near headwaters of the Utukok R., north slope of De Long Mts., Brooks Range, Alaska, ca. 68°53' N. Lat., 161°10' W. Long. (Steere 16900, Aug 4—16, 1951)» (Schuster, Steere, 1958: 192), though without any reference to the collection or institution of the type deposition (Turland et al., 2017: Art. 40.2, 40.7). Later, the gathering 16900 was divided, and its parts were distribu-
ted whithin the «Bryophytorum typorum exsiccata» series (Buck, 1981). Now its duplicates are deposited in several collections (see below, under isolectotypes). At least three specimens with no. 16900 are conserved at the Herbarium of the New York Botanical Garden (NY) where W. C. Steere worked. The images of two of them are presented on the site of the NY Herbarium (http://sweetgum.nybg.org/science/vh/specimen_details.php?irn=225619, barcode no. 00575535; http://sweetgum.nybg.org/science/vh/specimen_details.php?irn=225622, barcode no. 00575538), both being signed «Type» on their labels, so none of them can be considered the holotype. As far as we could trace, despite «isotypes» and «type» were mentioned in some subsequent publications, no formal designation of lectotype has been published so far (e. g., Steere, Inoue, 1978; Buck, 1981; Kis, 2004; Bakalin et al, 2012).
The type specimen with barcode no. 00575538 is designated here as the lectotype. Hygrolejeunea alaskana R. M. Schust. et Steere, 1958, Bull. Torrey Bot. Club, 85(3): 190. = Lejeunea alaskana (R. M. Schust. et Steere) Inoue et Steere, 1978, J. Hattori Bot. Lab. 44: 330.
Lectotype (designated here): United States of America. Alaska. North Slope. «Driftwood Camp, near headwaters of the Utukok River, north slope of De Long Mountains, Brooks Range, approx. 68°53' N. Lat., 161°10' W. Long. In wet depression, tundra hillside. W. C. Steere 16900, 16 Aug 1951». — NY: barcode no. 00575538 (isolecto NY 00575535 and 01289102, MICH 514782, TNS 60492, NICH 376515, EGR).
The gatherings nos. 16782, 16856, 16895, and 17037 cited in the protologue as «cotypes» are paratypes.
Acknowledgments. Help of W. R. Buck, A. Hagborg, D. F. Peralta and G. Winter with literature is appreciated. The study was carried out within the framework of the institutional research project AAAA-A18-118022090078-2 «Herbarium collections of BIN RAS (history, conservation, investigation and replenishment)» of the Komarov Botanical Institute of the Russian Academy of Sciences.
