Suttoniella S. Ahmad, Biologia, Lahore 6: 257 (1961) 
Facesoffungi number: FoF 07710
Ascomycota, genera incertae sedis
Saprobic on the host plant in terrestrial habitat. Sexual morph: undetermined. Asexual morph: Conidiomata dark brown, pycnidial, solitary to gregarious or confluent, immersed, oval or circular or irregular, unilocular, glabrous. Ostiole absent, dehiscence by irregular slits in the upper wall. Conidiomatal wall composed of thick-walled, dark brown to hyaline cells of textura angularis to textura prismatica. Conidiophores reduced to conidiogenous cells. Conidiogenous cells arising from inner layers of the basal stroma, hyaline, enteroblastic, polyphialidic, cylindrical to doliiform or irregular, determinate, smooth-walled, with 1–3 separate apertures restricted to the apical region. Conidia hyaline, triradiate, Y-shaped, aseptate, with two branches connected to the main axis by narrow isthmi, tapered towards the apices, smooth-walled (adapted from Sutton 1972a, 1980).
Type species: Suttoniella gaubae (Petr.) S. Ahmad, Biologia, Lahore 6(2): 128 (1961) 
Notes: Suttoniella resembles Cornutispora and Furcaspora in having hyaline, triradiate, Y-shaped conidia with aseptate main axis and arms (Nag Raj 1993, Punithalingam 2003). In Suttoniella and Furcaspora, the conidia are composed of main axes and arms which are constricted at base. However, the conidia of Cornutispora are unicellular, and bifurcate at the apex, resulting in two symmetrical arms or horn-like structures that are attenuated towards apex (Punithalingam 2003). Furcaspora was separated from Suttoniella as its arms and main axis bear an appendage at each end, and by its holoblastic, sympodial, conidiogenous cells (Nag Raj 1993, Punithalingam 2003, Crous et al. 2007).
Sutton (1972a) amended the generic diagnosis of Suttoniella and accepted two species, S. gaubae on Alyxia buxifolia (Apocynaceae) and Mangifera indica (Anacardiaceae), and S. eriobotryae (S. Ahmad) S. Ahmad. on Eriobotrya japonica (Rosaceae). Subramanian and Sudha (1980) and Hoyo and Gómez-Bolea (2004) added S. arnaudii Hoyo & Gómez-Bolea on Buxus sempervirens (Buxaceae) and S. ixorae Subram. & Sudha on Ixora parviflora (Rubiaceae). No molecular data is available for this genus. Fresh specimens are needed to clarify Suttoniella species.
Distribution: Australia, India, Pakistan, Spain (Sutton 1980, Punithalingam 2003, Hoyo and Gómez-Bolea 2004).
