Description

Not as big as The Parasol (Marcolepiota procera) or the Shaggy Parasol (Chlorophyllum rhacodes) but can still grow quite large. It has fewer obvious scales compared to that of some of the similar species. Starts off with a rounded cap which until it expands appears to have no ring. The ring itself can sometimes become free and fall to the bottom of the mushroom. 

Smell

Not distinctive. 

Season

Autumn.

Habitat & Distribution

Said to be more common in the south of the UK, it inhabits open deciduous woodland, pasture and often sand dunes and coastal grassland.

Edibility

Edible and good. Care should be taken to ensure you do not mistakenly pick the Shaggy Parasol (Chlorophyllum rhacodes) which can cause stomach pain and vomiting in some people.

Confusion Species

Spores 

13-17 x 8-10µm, smooth, ellipsoid.

Spore Print Colour

White.

Many of the other Parasols are similar, but this species does not have obvious dark scales like that of the Brown Parasol (Chlorophyllum brunneum), does not have the shaggy scales of that of the Shaggy Parasol (Chlorophyllum rhacodes) and does not have the ‘snakeskin’ like pattern on the stem like that of The Parasol (Macrolepiota procera).
