Leucocoprinus badhamii (Berk. & Broome) Locq. - Blushing Dapperling

Phylum: Basidiomycota - Class: Agaricomycetes - Order: Agaricales - Family: Agaricaceae

Leucocoprinus badhamii, Blushing Dapperling

All parts of this large dapperling turn blood red when cut or touched, and this is a very helpful field character. (The damaged flesh may eventually turn brown or almost black, so like human blushes the reddening is just a temporary effect!)

An uncommon sight in Britain and Ireland, but also found occasionally throughout most of northern and central mainland Europe, these large dapperlings are also reported from parts of western North America.

Taxonomic history

This chunky woodland mushroom was described in 1854 by British mycologists Miles Joseph Berkeley and Christopher Edmund Broome, who gave it the scientific name Agaricus badhamii. (Most gilled fungi were placed in the Agaricus genus in the early days of fungal taxonomy, but the majority have since been relocated to new genera.) In 1943 French mycologist Marcel Locquin (1922 - 2009) transferred this species to the genus Leucocoprinus, thereby establishing its widely accepted scientific name Leucocoprinus badhamii.

Synonyms of Leucocoprinus badhamii include Agaricus badhamii Berk. & Broome, Lepiota badhamii (Berk. & Broome) Quél., and Leucoagaricus badhamii (Berk. & Broome) Singer. (This latter synonym is currently preferred by some authorities.)

Leucocoprinus badhamii, Blushing Dapperling, showing stem ring and red staining


Leucocoprinus is derived from the Greek Leucos meaning white, and coprinus the genus name of inkcaps such as Coprinus comatus that are close relatives of the Field Mushroom. So Leucocoprinus suggests a group of white-gilled mushrooms that are in many respects similar to Agaricus species.

The specific epithet badhamii honours British physician, mycologist and writer Dr Charles David Badham (1805-1857), author of Treatise on the esculent funguses of England, which was published in 1847.

Odour 'mushroomy'; taste, sweet.

Habitat & Ecological role

Saprobic, usually in small groups in deciduous and mixed woodlands.


September to November in Britain and Ireland.

Similar species

Lepiota bruneoincarnata is similar but does not turn blood red when bruised.

Leucoagaricus leucothites has a white cap, gills and stem and does not blush red when bruised.

Culinary notes

These mushrooms are generally considered edible; however. there is a risk of confusion with one of the toxic white-gilled Lepiota species - for example the Stinking Dapperling Lepiota cristata - that can occur in the same kinds of habitat.
