The poisoning case in the municipality of Araucária was well documented. These symptoms usually occur within three hours after ingestion and spontaneously resolve without medical treatment. 1966), but Eilers and Nelson (1974) concluded that the toxin is probably not a choline derivative (cf.

Its distribution is indeed mainly tropical-subtropical. A few authors have suggested that there may be two (or more) morphologically distinguishable taxa (Heinemann 1968, Singer 1955), but such characters that would separate them remain insufficiently elaborated (Dennis 1970, Heim 1978, Singer 1975, 1979).
