Saprobic on sugar exudates from insects or foliar epiphytes on the upper surface of living leaves. Sexual morph: Mycelium superficial, black, composed of dark brown, reticulate-branched, hyphae, constricted at the septa. Ascomata scattered, superficial, subglobose to globose, black, with short stalk. Wall of ascoma multi-layered, inwardly hyaline of textura prismatica, dark brown towards the outside, comprised textura angularis. Asci 8-spored, bitunicate, ovoid to obpyriform, short pedicellate. Ascospores biseriate, fusiform, hyaline, phragmospores or muriform, with 3–5 transverse septa and 1–4 longitudinal septa, constricted at the septum, with guttules, narrow at the ends (Yang et al. 2018). Asexual morph: Mycelium composed of branched, septate, greenish-brown hyphae. Conidiophores lacking, reduced to a conidiogenous cell. Conidiogenous cells phialidic, intercalary, hyaline, with inconspicuous collarette, or sometimes proliferating percurrently. Conidia sickle-shaped, light brown, usually 3-septate, constricted at the septa, curved, widest in middle, apex rounded, base subtruncate, with a foot cell for germination, smooth-walled, guttulate (Crous et al. 2007, Réblová et al. 2013). 

Notes – Camptophora Réblová & Unter. was established to accommodate Camptophora hylomeconis (Crous, de Hoog & H.D. Shin) Réblová & Unter. transferred from Cyphellophora (Réblová et al. 2013). The genus is characterized by phialidic, intercalary, conidiogenous cells, with an inconspicuous collarette, or sometimes proliferating percurrently, and sickle-shaped conidia (Crous et al. 2007, Réblová et al. 2013). Phylogenetically, C. hylomeconis, Aphanophora eugeniae (Crous & Alfenas) Réblová & Unter. and Fumagopsis stellae Crous & A.J. Carnegie group together within Chaetothyriaceae (Réblová et al. 2013, this study). However, Camptophora has conspicuous phialides, with a single conidiogenous locus and sickle-shaped conidia, while A. eugeniae has inconspicuous collarettes, with aggregated loci and subcylindrical to cylindrical conidia, and it is apparently differentiated from F. stellae based on star-like conidia (Crous et al. 2007, 2018, Réblová et al. 2013). Yang et al. (2018) reported a sexual morph of C. schimae H. Yang & K.D. Hyde associated with sugar exudates from insects.

Type species: Camptophora hylomeconis (Crous, de Hoog & H.D. Shin) Réblová & Unter.

Other accepted species: Species Fungorum – search Camptophora.
