Agaricus dulcidulus - The Rosy Wood Mushroom

Small but rather attractive, this member of the Agaricus genus has a lovely pinkish flush and its stem turns yellow, often with an orange tinge, when bruised or cut.


A widespread but occasional find in Britain and Ireland, The Rosy Wood Mushroom fruits in deciduous woodlands, often in small groups. Found also in much of mainland Europe, Agaricus dulcidulus is also recorded in some parts of Asia and in North America.

Taxonomic history

Agaricus dulcidulus was first named and described in 1874 by Croatian mycologist Stephan Schulzer von Müggenburg (1802 - 1892) and the name that he gave it has remained generally accepted to this day, although in the interrim it has been given a few synonyms including Agaricus purpurellus F.H. Møller, Agaricus rubelloides Bon, Pratella rubella Gillet, Psalliota purpurella F.H. Møller, and Psalliota rubella (Gillet) Rea. (J. E. Lange referred to this species as Agaricus amethystina.)


The specific epithet dulcidulus comes from the Latin adjective dulcis, meaning sweet. This is a reference to the sweet taste/pleasant smell of this mushroom.
