S. flavolucens S. guadeloupense S. quercicola S. schizolomum S. subzebrinum S. vezdanum S. zebrinum Schizotrema is a genus of lichen-forming fungi in the family Graphidaceae.

[1] The genus Schizotrema consists of lichens with a thallus that can range from being immersed in the substrate to appearing more superficial.

The prothallus, a structure that sometimes surrounds the edges of the lichen, is faint and brown, blending subtly with the substrate.

The true exciple, the tissue surrounding the spore-producing region, is dark brown to black and multilayered.

The hamathecium, the network of sterile filaments within the hymenium, is composed of unbranched paraphyses with tips that are not thickened.
