Deniquelata
Deniquelata Ariyawansa & K.D. Hyde, in Ariyawansa et al., Phytotaxa 105(1): 13 (2013).
Index Fungorum number: IF 800703; Facesoffungi number: FoF 00034, 3 morphological species (Species Fungorum 2022), 3 species with molecular data.
Habit parasitic on living leaves. Sexual morph: Ascomata immersed, solitary, scattered, globose to subglobose, dark brown to black, smooth-walled, with a distinct ostiole, apex somewhat papillate to depressed. Peridium several-layered, outer wall composed of small, dark brown to black, heavily pigmented, thick-walled, comprising cells of textura angularis and fusing with the host, inner wall consists with broad yellowish-brown cells, inwardly lined by hamathecial tissues. Hamathecium of dense with pseudoparaphyses. Pseudoparaphyses broad, hyaline, embedded in a gelatinous matrix. Asci 8-spored, bitunicate, fissitunicate, clavate to broadly-clavate, with a short, broad, furcate pedicel, rounded at apex and with an ocular chamber. Ascospores biseriate, partially overlapping, oblong to narrowly oblong, reddish brown to dark yellowish brown, muriform, with three transverse septa and 1-2 vertical septa in the central cells when mature, constricted at the septa, verruculose, without a sheath. Asexual morph: Unknown (adapted from Ariyawansa et al. 2013).
Type species: Deniquelata barringtoniae Ariyawansa & K.D. Hyde
Notes: Deniquelata is characterised by globose to subglobose, dark brown to black ascomata, bitunicate, fissitunicate, clavate to broadly-clavate asci, and reddish brown to dark yellowish brown muriform ascospores. Ariyawansa et al. (2013) accommodated Deniquelata in Montagnulaceae based on morphology and multi-gene phylogenetic analyses. Deniquelata differs from Montagnula in having scattered ascomata, several-layered peridium, asci with short, broad, furcate pedicel, and reddish brown to dark yellowish brown, muriform ascospores while the type species of Montagnula, M. infernalis has clustered ascomata, brown to dark brown peridium comprising two distinct layers, asci with long stretching pedicels and brown ascospores (Zhang et al. 2012). Deniquelata also differs from Bimuria in that the latter has asci with short and small knob-like pedicel and ascospores without vertical septum and verrucose wall (Zhang et al. 2012, Ariyawansa et al. 2013). Deniquelata differs from Kalmusia in that the latter has long, narrowed asci with a furcate pedicel and ascospores with verruculose wall and 3 distosepta (Zhang et al. 2012, Ariyawansa et al. 2013). Deniquelata is morphologically and phylogenetically a distinct genus in Montagnulaceae. Molecular markers available for Deniquelata are ITS, LSU, SSU, Actin, Calmodulin, RPB2 and TEF-1.
