Brazilian Almond Egerling (Agaricus subrufescens )

The Brazilian Almond Egerling or short almond mushroom ( Agaricus subrufescens, syn A. brasiliensis, A. blazei ) is a species of fungus in the family of mushroom relatives. The name derives from the smell of the fruit body is similar to almonds. In addition, this mushroom is also known as sun mushroom and fungus life. The fungus has a slightly musty - sweet taste and is edible.

History

1947 described the U.S. taxonomist Murrill the fungus and published his discovery of Agaricus blazei Murrill under the name. However, in 2002 a group of scientists led by researchers showed Aquarius and Didukh that this species is identical to the already longer known mushroom Agaricus brasiliensis, so these older term, replacing the name of Murrill. The researcher Kerrigan succeeded in 2005 by DNA sequence analysis to prove that Agaricus brasiliensis ( Agaricus blazei Murrill and thus also ) is genetically identical to that described in 1893 mushroom Agaricus subrufescens Peck. The latter is thus the oldest name is the only science historically correct, so that the names of Agaricus blazei Murrill and Agaricus brasiliensis obsolete.

By other researchers, the identity of this species with Agaricus sylvaticus Schaeffer (German: Forest mushroom ) has been postulated for this but there is still no conclusive evidence. Both fungi are at least not easily distinguished because they are very similar.

Importance

Because of its high bD -glucan content, Agaricus subrufescens finds application in the alternative cancer therapy, mainly in Japan and California. Carefully designed studies that compare the therapeutic activity of isolated ingredients, full mushroom extracts and epidemiological data are still lacking. The toxicological aspects have also not been adequately studied. In Asia and South America subrufescens Agaricus is grown commercially detectable since 1993 and sold as edible mushroom.
