Neophyllis and the mazaediate genera Bunodophoron, Leifidium and
Sphaerophorus is suggested as a synapomorphy of the family

Conidiomata: Absent resp. not observed or present; pycnidial; immersed or sessile.

Conidiogeneous Cells: Apical or intercalar. Conidia: Bacilliform.

Secondary Metabolites: Present, of the following substance class(es): orcinol depsidones, ß-orcinol depsidones, diphenyl ethers, and dibenzofurans [and usnic acids].
