The bulk of the fungi in this sub-group produce hysterothecia as fruitbodies. A hysterothecium looks like a pair of black lips, no more than a few millimetres long. An individual hysterothecium is very hard to spot but hysterothecia usually turn up in large colonies. That makes spotting a little easier, but not guaranteed. A colony of a hundred fruitbodies may still occupy no more than a square centimetre or two.
One hysterothecial species, Glonium circumserpens, occurs on soil.
