Clathroporina subpungens thin section.

Clathroporina subpungens K stained thin section.

In thin section the unstained interior wall of the perethecial cavity is yellow. This trait is shared, to some degree, by the other 2 members of the genus.

When treated with potassium hydroxide the cavity interior wall becomes reddish, a helpful diagnostic test.
