Chuppia Deighton, in Deighton & Pirozynski, Mycol. Pap. 101: 32 (1965)
Saprobic or parasitic on leaves of solanaceous dicotyledonous plants. Sexual morph: Undetermined. Asexual morph: Hyphomycetous. Colonies effuse, dark brown to black. Mycelium superficial, densely aggregated composed of brown, branched, septate hyphae. Conidiophores micronematous, mammalliform, flexuous, irregularly branched, yellow brown to dark olive brown, smooth, arising separately as lateral protrusions of swollen intercalary hyphal cells. Conidiogenous cells holoblastic, integrated, terminal or intercalary, determinate, cylindrical, and denticulate, with conical denticies. Conidia solitary, pleurogenous, simple, ellipsoidal, irregular in shape, muriform, multicellular, formed separately as blown-out ends of the sporogenous cells which ruptures when the conidium is shed, constricted at the septa, with a basal protuberant hilum, dark yellow brown, smooth to verruculose-walled.
Type species – Chuppia sarcinifera Deighton
Notes – The monotypic genus Chuppia has been established by Deighton with C. sarcinifera Deighton as the type species (Matsushima 1975). The latter was isolated from leaves of Solanum lanugiflorum in Venezuela. Deighton (1965) placed the genus Chuppia in the family Dematiaceae of the order Hyphomycetales. The genus is characterized by effuse, dark brown to black colonies, superficial, densely aggregated mycelium composed of brown, branched, septate hyphae, micronematous, flexuous, irregularly branched conidiophores and muriform, sarciniform conidia with protuberant hilum. Currently, two species are accommodated in the genus Chuppia (Index Fungorum 2019). The sexual morph is unknown. Sequences and cultures are unavailable. We re-examined the holotype specimen from CUP herbarium under the code CUP-VZ-002114 and illustrate the morphological characters. In this study, we retain the genus Chuppia in Dothideomycetes genera incertae sedis. Fresh specimens and sequence data are required for this genus.
