Taxonomic remark Treated as Family Issinellaceae, Class Algospongia (Algae incertae sedis) in IRMNG following Vachard et al., 2016. For an alternative view see Feng et al., 2010, who note: The identity of Issinella is linked to those of taxa such as Jansaella Mamet and Roux, 1975, Uraloporella Korde, 1950 and, to a lesser extent, Nanopora Wood, 1964. ... They have all often been compared with dasycladalean and udotealean green algae. ... Reitlinger (1954) considered Issinella to possibly be a dasycladalean green alga. Occurrence of these fossils as fragments often makes it difficult to judge whether the absence of features such as branching and septa is fortuitous. This complicates not only taxonomic assignment, but also interpretation of affinity. Septa, and the style of branching that can be seen, for example, in Jansaella ridingii, preclude dasycladalean and udotealean affinities (Riding and Jansa, 1974, p. 1422; pl. 1, fig. 4). Riding and Jansa’s (1974, p. 1421) recommendation that the systematic position of these fossils needs to be reviewed remains valid. [details]
