Taxonomic remark "String-of-beads fossils" of disputed origin. From Dong et al., 2008: "Horodyskia was interpreted as inorganic sedimentary structures (Horodyski 1982, 1983), dubiofossils (Fedonkin & Runnegar 1992), or pseudofossils (Hofmann 1992). Grey & Williams (1990) proposed its probable biological origin with affinity to the Phaeophyceae. Recently, Horodyskia was reinterpreted as a tissue-grade colonial eukaryote (Fedonkin & Yochelson 2002)." Retallack et al., 2013 consider to be fungal (endolichen bladders), while Rule & Pratt, 2019 consider this genus to be a pseudofossil. Dong et al. compare this genus with Palaeopascichnus, "recently reinterpreted as a giant rhizopodan protist similar to modern deep-sea xenophyophores (Seilacher et al. 2003), a group of agglutinated foraminifers (Tendal 1972; Pawlowski et al. 2003b)."
