dominant cell type textura angularis continuous with stroma be-low, of cells 5-20 (-30) µm wide, cell walls 1-3 µm thick, usually with larger cells in centre[4]
arising directly from textura angularis, or in stipitate collections textura angularis elongating into a zone of textura prismatica to textura porrecta 100-200 µm long, of cells 3-5 µm wide[4]
