Melaspilea mangrovei Vrijmoed, K.D. Hyde and E.B.G. Jones

Mycol. Res. 100: 291-294, 1996

Ascomata: lirelliform (a long, narrow apothecium), appearing as black elongate areas, on the host surface, up to 2.5 mm long and 0.5 mm wide, coriaceous, with a permanent opening along the entire length to expose the hymenium, solitary or gregarious.

Asci: 71-111 x 30-40 m, 8-spored, clavate, thick-walled, bitunicate, with rostrate dehiscence, with an ocular chamber, wall staining blue in Melzer’s reagent.

Ascospores: 24-28 x 12-14 m, 2-3-seriate, hyaline, some mature spores becoming light-brown, ellipsoidal, 2-celled, constricted at the septa, lower cells 12-18 m, upper cells 10-14 m, smooth-walled, with a mucilaginous sheath. The sheath may rupture at both poles at maturity to form a band or ‘skirt’ at the septum to which it appears to be attached.
