Lectotype (designated here): [illustration] in Kosmos (Lvov) 50: t. 1, fig. 26. 1925! [showing a non-fossil individual; exact locality and collecting date unknown: R. Dreżepolski s.n.] – Epitype (designated here): Republic of Ukraine. Lviv, Lubień Mały, 15 Sep 2012 [non-fossil]: C. Zinssmeister, N.H. Filipowicz & M. Gottschling P39 [J. Kretschmann GeoM 527] (KW No. KW-A-222! ; isoepitypes: B barcodes B 40 0043802! & B 40 0043803! , KW No. KWA-223! , M barcodes M-0299989! & M-0299990! ).

The nomenclatural act has been registered in PhycoBank under http://phycobank.org/100569.

Other original elements. – Non-fossil specimens from Dobrostany and Lviv ( Ukraine), Łuków ( Poland) and Tuhanowicze ( Belarus), without exact date (May, Jul, Sep, Nov), collected by R. Dreżepolski, none preserved.

Note. – Average length, width and shape of the strain GeoM 527 correspond to the protologue data. Double-husked pyrenoids are not seen in all the cells, yet the subclade within strain GeoM 527 clustered is known to possess diplopyrenoids ( Ciugulea & al., 2008). Additionally, absence of collar (seen in SEM and LM images) and overall smooth surface (seen in LM images) are also in correspondence with the protologue. Finally, samples were collected in September, which also correlates with the original description.
