Taxonomic remark From Schlagintweit et al., 2010: "Originally described as a siphonal (= non-septate filaments) codiacean alga ... other authors proposed a sponge (Koch et al. 2002) or red alga origin (Wood 1999, p. 102), interpreted it as a lituolid foraminifera (Schmid and Leinfelder 1996) or assumed a microbial (= cyanobacterian) origin. ... The possible foraminiferan nature of Lithocodium aggregatum proposed by Schmid and Leinfelder (1996) was discussed and rejected by Schlagintweit et al. (2005), Cherchi and Schroeder (2006) and Schlagintweit (2008). Nonetheless, other authors accepted the interpretation of Schmid and Leinfelder (e.g., Kolodzjei 1997; Dupraz and Strasser 2002; Flügel 2004; Helm 2005). In the two paleobiological online databases (www.data.gbif.org, www.paleodb.org), Lithocodium is treated as a genus within the phylum Cyanobacteria. ... [in this paper] Lithocodium is re-interpreted as a Wlamentous-septate heterotrichale ulvophycean alga (?order Ulotrichales)." However, according to Cherchi & Schroeder, 2012, the holotype of Lithocodium aggregatum, the type species, represents "a sponge–calcimicrobe consortium". [details]
