Ribes hudsonianum Ribes hudsonianum Ribes hudsonianum is a North American species of currant, known by the common name northern black currant. "Ribes hudsonianum" grows in moist wooded areas, such as mountain streambanks and in swamp thickets. They are upright to erect shrubs growing one half to 2 meters (20-80 inches) tall. They are aromatic, with a strong scent generally considered unpleasant. Stems are covered in shiny, yellow resin glands that lack spines or prickles. Leaves are up to 10 centimeters long, divided into three, or rarely five, sharp-toothed lobes, having long hairs on the undersides, studded with yellow glands. Inflorescences are erect,
Epicoccum nigrum versicolor", "E. vulgare", "E. granulatum", "E. menispermi", and "E. neglectum". More recently, two distinct genotypes for "E. nigrum" have been identified with the combined use of DNA sequencing, morphology, physiology, and recombination factors. This indicates the existence of cryptic species, and a subsequent call to re-classify "E. nigrum" into more than one species. 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
