Craterellus fallax is a species of “black trumpets” that occurs in Eastern North America where it replaces the European taxon Craterellus cornucopioides. C. fallax can also be separated by its yellow-orange spore print, where Craterellus cornucopioides has a white spore print.

A quick look at some nutrition labels may reveal the presence of vitamin B12 – for example, in the cyanobacterium sprirulina – however, what some foods actually contain is a biologically inactive form of B12, known as pseudo-B12. Vitamin B12 and pseudo-B12 are not the same; only the former is biologically active in the human body and therefore able to correct deficiencies.

Enter black trumpets: According to the Journal of Agricultural and Food Chemistry (2013), black trumpet (Craterellus cornucopioides) mushrooms contain considerable amounts of biologically active vitamin B12 (1.09−2.65 μg/100 g dry weight), and may improve vitamin levels in those experiencing deficiencies.
