Description

Leiorreuma is identified by certain features. It has apothecia with noticeable sessile opened lirellae. The proper exciple is often thin on the sides but well-developed at the base and appears charred. The hymenium is dotted with small specks, and the spores are pale brown and have thin walls with crosswise septa or are divided into many compartments (muriform). They are not stained by iodine.[2]
