The fungi of the order Myriangiales have fruiting bodies without openings and the ascospores are released when the tissue above the asci breaks up. The asci are irregularly arranged in one or more layers in locules. Each locule contains only one or several asci. The asci have minute pedicel and indistinct ocular chambers. The order is more precisely characterized by the DNA structure of its members.
