THE GENUS AMANITA. 



The genus Amanita, which is made up of large and con- 

 spicuous species (some of which are very poisonous, while 

 others are edible) is probably the best figured and described 

 genus of the agarics. The figures of A. muscaria, phalloides etc. 

 are legion, and even the less important species are mentioned 

 and described in almost every mycological textbook. 



Still I have not deemed it superfluous in my »Danmarks 

 Agaricaceer« to give watercolour-portraits also of this impor- 

 tant genus. Even if most of the prominent species are very 

 well known and cannot easily be mistaken, no little uncertainty 

 exists with regard to some of the more trivial species and certain 

 intermediate forms, the conception of which is rather vacillatory. 

 — And this uncertainty cannot be brought to an end without a 

 synoptic comparison of all the species in question. As, however, 

 many species are rare and may be sought in vain for years, 

 this comparison — practically speaking — can only be brought 

 about by comparing portraits (which — to exclude differences 

 due to the individual artists — should be executed all by the 

 same hand). 



Given such a portrait-collection (accompanied by spore- 

 measures and other microscopic data) it will be comparatively
