Cleistothecium

Closed cleistothecium of Uncinula necator

A Cleistothecium or Kleistothecium is a type of fruit bodies as in some sac fungi occurs (Ascomycota).

A cleistothecium is an almost round Ascoma without a preformed opening, with a single or multi-layered wall. Cleistothecia are often surrounded by envelope cells or peridia . The spores are released by mechanical destruction of the cleistothecium or by swelling of internal structures that cause the cleistothek to burst.

Cleistothecia are formed, for example, from the genera Emericella and Eurotium .
