Ramaria

About

The genus Ramaria comprises approximately 200 species of coral fungi. Several, such as Ramaria flava, are edible and picked in Europe, though they are easily confused with several mildly poisonous species capable of causing nausea, vomiting, and diarrhea; these include R. formosa and R. pallida. Three Ramaria species have been demonstrated to contain a very unusual organoarsenic compound homoarsenocholine.
