Agaricus sylvicola: The Ultimate Mushroom Guide
About The Agaricus sylvicola Mushroom
Agaricus sylvicola is a species of Agaricus mushroom related to the button mushroom. It is edible and popular in Europe.
This mushroom grows in both deciduous and coniferous woodland in Britain, Europe, and North America. Appearing in the autumn, it is rarely seen in huge numbers, usually just a few, or solitary.
With a noticeable aniseed smell and a smooth cap that slowly colors ochre when bruised, Agaricus sylvicola is quite easily distinguished from the other large mushrooms in the family Agaricaceae.
This species is often misspelled as Agaricus Silvicola.
Other names: Woodland Agaricus, Large Floppy Annulus.
Agaricus sylvicola Identification
Cap 6.0-12.0 cm broad, globose to deeply convex, becoming convex to plano-convex at maturity; margin incurved, then decurved, eventually straight; surface dry, white, glabrous to innately fibrillose, in dry weather sometimes squamulose; yellowing slowly when bruised or with age, yellow with KOH; context firm, white, unchanging, up to 1.5 cm thick; the odor of anise or almonds; taste mild.
Gills free, close to crowded, moderately broad, pallid in youth, blackish-brown in age; edges lighter than the faces.
Stipe 6.0-12.0 cm long, 1.5-2.0 cm thick, equal, clavate, sometimes bulbous, hollow to stuffed; the surface of apex whitish, fibrillose-striate, lower stipe colored like above, more or less glabrous, stipe base slowly bruising yellowish to tawny; context white unchanging; veil double, the lower surface white, matted-tomentose, splitting radially in cogwheel fashion revealing a similarly textured often fissured under-layer; annulus white, thin, the margin blunt, pendulous, attached high on the stipe.
Spores 5.5-6.5 x 3.5-4.0 µm, ellipsoid, smooth, moderately thick-walled; hilar appendage conspicuous.
Solitary or in small groups in mixed hardwood-conifer forests; fruiting from late fall to mid-winter; uncommon.
Agaricus sylvicola Look-Alikes
The Horse Mushroom, is similar in appearance and also has an aniseed smell; it appears in grassland, often growing in rings. Apart from the very different habitat, it would be possible to mistake Wood Mushrooms for Horse Mushrooms, because they look and smell quite similar; however, the stem base of Agaricus sylvicola is relatively longer and slimmer, and it has a noticeably bulbous base.
Quickly stains chrome yellow, both at the edge of the cap and especially when the base of the stipe is cut; it smells of ink or iodine rather than of aniseed.
Shorter, stockier mushroom with a white cap and strong yellowing reaction when bruised.
Agaricus sylvicola Taxonomy & Etymology
First described scientifically in 1832 by Italian obstetrician and mycologist Carlo Vittadini (1800 - 1865), this woodland mushroom was considered simply a variety of the Field Mushroom Agaricus campestris var. sylvicola. In 1873 an American botanist-mycologist, Charles Horton Peck (1833 - 1917) raised the status of this mushroom to full species level, naming it Agaricus sylvicola.
Synonyms of Agaricus sylvicola include Pratella flavescens Gillet, Psalliota sylvicola (Vittad.) Richon & Roze, and Agaricus essettei Bon. Some authorities treat Agaricus essettei (syn. Agaricus abruptibulbus) as synonymous with Agaricus sylvicola;others treat this chunky mushroom, with its more bulbous stem and on average slightly larger spores, as a distinctly separate species.
The specific epithet sylvicola means 'inhabiting woods'.
