Type species – Acanthonitschkea argentinensis Speg.

Notes – Acanthonitschkea argentinensis has spinate ascomata and clavate asci with reniform
ascospores (Spegazzini 1908). It was considered as a member of Coronophoraceae (Müller & von
Arx 1973, von Arx 1981a, Subramanian & Sekar 1990). Mugambi & Huhndorf (2010) transferred
the genus to Nitschkiaceae based on multi-gene analysis. The genus is closely related to
