Type species – Xenoastrosphaeriella tornata (D. Hawksw. & Boise) Jayasiri & K.D. Hyde, Mycosphere 10(1): 36 (2019).

≡ Trematosphaeria tornata Cooke, Grevillea 16(no. 79): 91 (1888).

Notes – Xenoastrosphaeriella was introduced by Jayasiri et al. (2019) mainly based on phylogenetic analyses. Xenoastrosphaeriella is similar to Astrosphaeriella because of mammiform to conical, carbonaceous ascostromata and fusiform, reddish brown ascospores (Hawksworth & Boise 1985). In this paper, we synonymize Astrosphaeriella trochus as Xenoastrosphaeriella trochus based on phylogeny and morphology.
