Type species – Muellerites juniperi (E. Müll. & Arx) L. Holm, Svensk bot. Tidskr. 62: 231 (1968).

≡ Gibberidea juniperi E. Müll. & Arx, Phytopath. Z. 24: 359 (1955).

Notes – There is only one species of Muellerites described on leaves of Juniperus nana Willd. (Cupressaceae) in Switzerland. Muellerites is characterized by globose, small, black ascomata, forming at the base of the cypress leaves, a single thick-walled layered peridium, with 8- spored, cylindrical asci, and 3–4-septate, dark brown ascospores (Dai et al. 2014). Based on the morphological characters, Dai et al. (2014) placed Muellerites in Dothidotthiaceae, but Crous (2018a) re-examined and re-positioned the genus to Neocelosporiaceae based on sequence data of the type species.
