Bracteacoccus Tereg.

This coccoid aero-terrestrial genus can be characterized by multinucleate, round cells that are solitary or form irregular colonies, multiple distinct plate-like plastids without pyrenoids and reproducing by zoospores or aplanospores (Fig. 18; Ettl & Gärtner 2013). Fučíková et al. (2014) place this genus with its 16 accepted species (Guiry & Guiry 2022) in the Sphaeropleales . Its ability to form lichens (genus Sulzbacheromyces) was supported by morphological as well as sequence data (Takeshita et al. 2010; Hodkinson et al. 2014; Masumoto 2020). According to Masumoto (2020), Sulzbacheromyces isolates of Bracteacoccus sp. formed two separate clades that were distinct from free-living taxa.
