|'''描述:'''Thalli microscopic,    unicellular or in few-celled aggregations. Cell wall hyaline to brownish    with 16-40 longitudinal striations with polar thickenings absent or poorly    developed; ultrastructurally, cell wall with inner, mostly polysaccharide    layer and outer trilamellate layer created by coalescence of trilaminar    plates produced via ER-derived vesicles; outer cell wall layer with    undulate outline. Cell walls contain acetoresistant material, often thicken    and peel off. Cells with numerous conspicuous vacuoles. Cells uninucleate,    apparently without centrioles; chloroplast single and parietal consisting    of polygonal, parietal plates or strips; pyrenoid single per cell with    homogeneous stroma and surrounded by starch grains. Mature cultures brick    red. Asexual reproduction by autospores, 2-16 per cell; released by rupture    of parental cell wall. Flagellated stages and sexual reproduction unknown. 此圖只是Coelastrella其中一種形態。
