=Cucullospora mangrovei (K.D. Hyde & E.B.G. Jones) K.D. Hyde & E.B.G. Jones, Bot. Mar. 29: 491. 1986.

Saprobic on mangrove wood, sexual morph: Ascomata: 150–220 µm high, 250–380 µm diam., subglobose, ovoid to ellipsoidal, greyish brown to black, coriaceous, immersed, solitary or gregarious, ostiolate. Peridium: 27–45 µm thick, composed of an inner layer of elongate cells and an outer layer of thick–walled rounded cells. Necks: 230–330 µm long, 50–75 µm diam., periphysate. Asci: 180–(212)–250 x 36–(41)–46 µm, thin–walled, unitunicate, 8–spored, clavate, persistent, thickened at the ascus tip with a lens–shaped refractive region, pedicellate. Catenophyses: present. Ascospores: 48–(57)–64 µm x 16–(19)–24 µm, hyaline, fusoid to ellipsoidal, 1–septate, not constricted at the septum, appendaged. Appendages: 6–12 µm x 4–8 µm, arising from an extension of the spore wall, unfurling into fine thread in water.

Comments:
NOTES: Cucullosporella mangrovei was originally described from mangrove wood collect and Brillant mangrove, Seychelles as Cucullospora, an invalid name that was changed to Cucullosporella by Jones & Hyde (1990). The ascomycete belongs to a group of aquatic fungi with ascospores with polar hamate appendages that unfurling to form fine thread–like appendages (Alias et al. 2001, Pang et al. 2003). It differs from other such genera in having a polar tube–like structure through which the thread–like appendages are extruded. Molecular studies place it in the Halosphaeriaceae forming a sister group to Aniptodera longispora (=Paraaniptodera longispora) (Sakayaroj et al. 2011, Jones et al. 2017).
