Pleosporales

Halojulellaceae

Halojulella Suetrong, K.D. Hyde & E.B.G. Jones, Phytotaxa 130(1): 18 (2013).

 Index Fungorum number: IF 803342; Facesoffungi number: FoF 08246, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.

      Saprobic on young twigs and woody tissue of mangrove trees. Sexual morph: Ascomata subglobose, pyriform or ellipsoidal, immersed becoming erumpent, short papillate, ostiolate, formed under a clypeus, coriaceous, brown to dark brown, solitary or gregarious Peridium one layered, wall composed of small, dark brown to black, heavily pigmented, thick-walled cells of textura angularis and fusing at the outside with the host. Hamathecium of septate cellular, hyphal-like, pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, with a distinctive apical apparatus, clavate to cylindrical with moderately long pedicel with club-like base. Ascospores 2-seriateor partially uniseriate, ellipsoidal, muriform, 7-8 trans septate, 1-longiseptate, constricted at the septa, hyaline to golden brown at maturity, with a gelatinous sheath. Asexual morph: Pycnidia in culture brown, thin-walled, ostiolate; Conidiophores filiform, septate, branched. Conidia hyaline, aseptate, thin-walled, guttulate, ellipsoidal (adapted from Ariyawansa et al. 2013).

       Type species: Halojulella avicenniae (Borse) Suetrong, K.D. Hyde & E.B.G. Jones

            Notes: Halojulella is characterised by subglobose, pyriform or ellipsoidal ascomata, heavily pigmented, thick-walled peridium, bitunicate, fissitunicate 8-spored asci, and 2-seriateor partially uniseriate, ellipsoidal, muriform, 7−8 trans-septate ascospores. H. avicenniae, previously known as P. avicenniae was transferred to Julella by Hyde (1992c). Halojulella differs from Julella in that the latter has 2-spored asci and no apical apparatus while the former genus has 8-spored asci with a distinct apical apparatus (Suetrong et al. 2009, Zhang et al. 2012). Halojulella differs from other genera in Pleosporales in having immersed ascomata below a clypeus, a single layered peridium of elongated cells and cellular, hyphal-like, pseudoparaphyses. Halojulella is a well-supported genus in its own family Halojulellaceae. Molecular markers available for Halojulella are ITS, SSU, RPB2 and TEF-1.
