Their location may be marginal or set away from the margin on the frond lamina. The presence or absence of indusium is also used to identify fern taxa. 254: 389: 335: 347: 192:
and other fungi, the sorus is surrounded by an external layer. In some red algae, it may take the form of depression into the thallus.
