Brown Parasol
Poisonous 
Autumn 
Summer 
One of the large parasol-lookalikes, a controversial member of the ‘shaggy parasols’. Its edibility ranking is not conclusive, so it is worth knowing its ID features to avoid any troubles.
| Mushroom Type | |
| Common Names | Brown Parasol, Czubajnik Ogrodowy (PL), Kerti Őzlábgomba (HU) |
| Scientific Name | Chlorophyllum brunneum |
| Synonyms | Macrolepiota rhacodes var. hortensis, Macrolepiota bohemica, Lepiota rhacodes var. hortensis, Lepiota brunnea |
| Season Start | Jun |
| Season End | Nov |
| Average Mushroom height (CM) | 5–20 |
| Average Cap width (CM) | 10–18 |
Cap
10–18 cm across. Hemispherical, then convex to flattened with a broad, pronounced umbo or a central depression. The skin is dark ochre-brown at first, then cracks up and becomes scaly, making the pale, almost white, fluffy flesh visible. The central umbo remains complete. Margin is often floccose.
Gills
Crowded and free of the stem. White at first, spotted reddish brown with age. The edge is darker, somewhat brownish and slightly eroded.
Stem
5–20 cm long, 1–2.5 cm diameter. White to cream, smooth, browning with age. Cylindrical, more or less straight with a large, marginate bulb at the base, which could be up to 5 cm wide.
Skirt
Has a single layered skirt, which is brown on the underside. You can move it up and down on the stem.
Bulbous Base
Has a large marginate, almost volva like bulbous base. This is a good ID for helping to separate the Brown Parasol from the Shaggy Parasol.
Flesh
Thick, soft and white in the cap, bruising orangish- to reddish-brown when exposed to air.
Habitat
Fruiting solitarily or in smaller groups. Grows on disturbed, nitrogen-rich soil, such as compost heaps, gardens, parklands; or on woodchip/mulch amongst shrubs and various trees. Rarely, but it can be found in mixed forests too. Saprotrophic.
Possible Confusion
It can be confused with other members of the genus Chlorophyllum, especially the shaggy parasol (Chlorophyllum rhacodes), pictured. The large, marginate, bulbous base of the Brown Parasol can help separate the two.
Taste / Smell
Smells earthy, tastes mealy. However, hence its edibility is in question, we don’t recommend eating it.
Frequency
Common and widespread.
Spores
Spore print is white. Spores are broadly ellipsoid, colourless (hyaline), thick-walled, smooth and dextrinoid (turning reddish-brown in Melzer’s reagent), and they have a small germ-pore.
Other Facts
We have four different Chlorophyllum species in the UK. The more or less edible shaggy parasol (Chlorophyllum rhacodes) and conifer parasol (Chlorophyllum olivieri), also the brown parasol (Chlorophyllum brunneum) with questionable edibility and the toxic false parasol (Chlorophyllum molybdites), the latter is probably more well-known by its US name: the vomiter.
The debate about the edibility of brown parasol is still unsettled. Andy Overall lists it as ‘Not Edible’ and in some European countries the species is listed ‘Toxic’, based on actual mushroom poisoning cases, so we list it as toxic (as we always follow the ‘better safe than sorry’ philosophy).
