Notes: Astrocystis was introduced by Berkeley and Broome (1873) and typified by Astrocystis mirabilis. Index fungorum (2022) lists 28 epithets in Astrocystis, while four of them have been excluded from this genus. Species of this genus mainly exist in saprobes on monocotyledonous substrates, such as bamboo, palm and Smilax (Laessøe and Spooner 1993). Astrocystis is characterized by uni- to multi-peritheciate stromata, carbonaceous peridium, asci with a relatively short stipe and small, amyloid, stopper-shaped ascal ring (Pinnoi et al. 2010). It is widely accepted that Astrocystis bear similar morphology with Rosellinia, while the former genus can be distinguished from the latter by small and cylindrical or funnel-shaped apical ring of asci. Rosellinia has conspicous, barrel-shaped apical apparatus (Dulymamode et al. 1998).

Type species: Astrocystis mirabilis Berk. & Broome, J. Linn. Soc., Bot. 14(no. 74): 123 (1873) [1875]

Other accepted species: Species Fungorum – search Astrocystis.
