Jostaberry Jostaberry The jostaberry ("Ribes" × "nidigrolaria") is a complex-cross fruit bush in the genus "Ribes", involving three original species, the black currant "R. nigrum", the North American coastal black gooseberry "R. divaricatum", and the European gooseberry "R. uva-crispa". It is similar to "Ribes × culverwellii", the Jochelbeere, which is descended from just two of these species, "R. nigrum" and "R. uva-crispa". The cultivated plants are tetraploid. They are descended from two separate first-generation crosses, both of which produced very few fruit. Fertile tetraploids were produced using colchicine. The name "Jostaberry" was created via combining the German words for blackcurrant and
Epicoccum nigrum Epicoccum nigrum Epicoccum nigrum is a species of fungus, in the phylum Ascomycota. A plant pathogen and endophyte, it is a widespread fungus which produces coloured pigments that can be used as antifungal agents against other pathogenic fungi. The fluorescent stain, epicocconone is extracted from it. "Epicoccum nigrum" (1825) Link ex. Link is a fungus with no known teleomorph form. It has been classified as a member of the Hyphomycetes, in the Deuteromycota, as well as the Fungi Imperfecti because it is only known to reproduce asexually. Despite that it is not yeast-like, it has been included in the broad,
