Jaagichlorella Darienko & Pröschold. View in CoL

Jaagichlorella View in CoL possesses uninucleate solitary, usually spherical cells with one saucer-like (in young cells) or band-like (mature cells) chloroplast containing a single pyrenoid ( Fig. 6 View Figs 1–18 ; Darienko & Pröschold 2019). Recently, the tropical genus Heveochlorella View in CoL was synonymized with Jaagichlorella ( Darienko & Pröschold 2019) View in CoL , but this taxonomic treatment was overlooked by some authors ( Lindgren et al. 2020; Sanders & Masumoto 2021). The genus is an important member of algal communities in the tropical phyllosphere ( Zhu et al. 2018) and represents the most common genus of photobionts of Sticta ( Lindgren et al. 2020) View in CoL . According to Sanders et al. (2016), Jaagichlorella View in CoL can be easily cultivated and probably exhibits both lichenized and free-living lifestyles. Further support for this view is direct observations conducted on plastic coverslips ( Sanders 2014; Sanders & Masumoto 2021).
