Stropharia aeruginosa (Curtis ex Fr.) Quél. 1872
Family : Strophariaceae
Common names: Verdigris agaric, Blue-green stropharia [En], Strophaire vert-de-gris [Fr], Grünspan-Träuschling [De]

Meise, BRABANT ● Belgium

Taxonomy: The French mycologist Lucien Quélet gave it its current binomial name in 1872, after it was initially described as Agaricus aeruginosus by William Curtis in 1784. The Dutch mycologist Machiel Noordeloos placed it in the genus Psilocybe in 1995. The specific epithet aeruginosa is Latin for "covered in verdigris (copper-rust)". From 1995, it has been moved to the Stropharia genus.

Description: The cap is convex, broadening, and becoming umbonate with age. It is from 2–8 cm in diameter. At first it is a vivid blue/green, and very glutinous (slimy), with a sprinkling of white veil remnants around the edge. The colour in the gluten fades, or is washed off as it matures, and it becomes yellow ocher, sometimes in patches, but mostly at the centre. Finally, it will lose the blue-green coloration completely. The stem is quite long and of uniform thickness. It has a fragile brown/black ring, and below this the stem is covered in fine white scales, or flakes. The gills are initially white, then clay-brown, and sometimes have a white edge. The spore print is brownish-purple, and the oval spores 7–10 x 5 μm.

Biology : It can be found from spring to autumn.

Habitat: Grassy woods, and on roadside verges.

Distribution: Europe, Asia and parts of North America.
