Like a sleeve green Oreo cookies! Discoid cells appear to be loose within the trichome cell wall, most cells packed perpendicular to to the long axis of the strand, providing a lateral view of the cells. Occasionally, however, cells are tipped giving a partial or full apical view. What is this, @roman_romanov!? Stigonema?

Estuary shoreline sample (brackish). These loricae were relatively common (saw ~6 after scanning a 24x50mm field on one slide). Initially thought these were the loricae from a lobose aomeba, but found images of the peritrich, Pyxicola pusilla in a journal article that correspond very well. Perhaps the 2 specimens I show here are from a closely related genus or specie. https://www.researchgate.net/publication/345494459_Novel_contributions_to_the_peritrich_family_Vaginicolidae_Protista_Ciliophora_with_morphological_and_phylogenetic_analyses_of_poorly_known_species_of_Pyxicola_Cothurnia_and_Vaginicola/figures

Difficult to resolve (need phase (@bdstaylor !) - Each cell appears to have 3 appendages that seem to form a tripod. These appendages did not move nor did the cell swarm (as Diplophrys did in a colonial setting, see https://www.inaturalist.org/observations/72584434). I'm completely stumped with this one.
