Type species – Wallrothiella congregata (Wallr.) Sacc.
Notes – Wallrothiella was introduced by Saccardo (1882) and re-described by Réblová & Seifert (2004b) based on new collections; a neotype for W. congregata, the type species of the genus, was proposed. Wallrothiella is characterized by the absence of stromata, globose to subglobose ascomata with a rostrate neck, sometimes surrounded by a whitish subiculum, and tiny, globose ascospores in cylindrical asci.
