Comments

Family Papposphaeraceae description: Diploid phase motile; coccospheres covered in pappoliths. A central process is often prominent. Each pappolith is constructed of a rim of two lath types, one small and confined to the proximal part of the wall, the other vertically expanded; central area with variable structures. Haploid phase motile, with holococcoliths typically with tower-like forms.
