Agrocybe pediades, commonly known as the common fieldcap or common agrocybe,{{Cite book |last=Arora |first=David |author-link=David Arora |url=https://archive.org/details/arora-david-mushrooms-demystified-a-comprehensive-guide-to-the-fleshy-fungi-ten-speed-press-1986/page/468/mode/2up |title=Mushrooms Demystified: A Comprehensive Guide to the Fleshy Fungi |publisher=Ten Speed Press |year=1986 |isbn=978-0-89815-170-1 |edition=2nd |location=Berkeley, CA |pages=468-69 |orig-date=1979}} is a species of fungus. It can be found on grassland. It is potentially edible, but it could be confused with poisonous species, including one of the genus Hebeloma.
Taxonomy
It was first described as Agaricus pediades by Swedish mycologist Elias Magnus Fries in 1821, and moved to its current genus, Agrocybe, by Victor Fayod in 1889. A synonym for this mushroom is Agrocybe semiorbicularis, though some guides list these separately.{{cite book|last=Phillips|first=Roger|url=https://archive.org/details/mushroomsotherfu0000phil|title=Mushrooms and Other Fungi of North America|publisher=Firefly Books|year=2010|isbn=978-1-55407-651-2|location=Buffalo, NY|pages=[https://archive.org/details/mushroomsotherfu0000phil/page/226 226]–27|url-access=registration}}
Description
The mushroom cap is 1–3 cm wide, round to convex (flattening with age), pale yellow to orangish-brown, smooth but sometimes cracked, and tacky with moisture but otherwise dry.{{Cite book|last1=Davis|first1=R. Michael|title=Field Guide to Mushrooms of Western North America|last2=Sommer|first2=Robert|last3=Menge|first3=John A.|publisher=University of California Press|year=2012|isbn=978-0-520-95360-4|location=Berkeley|pages=238–239|oclc=797915861}} The stalks are 2–7 cm long and 1–4 mm wide.{{Cite book |last=Audubon |title=Mushrooms of North America |publisher=Knopf |year=2023 |isbn=978-0-593-31998-7 |pages=662}} A partial veil quickly disappears, leaving traces on the cap's edge, but no ring on the stem.{{cite book|last1=Trudell|first1=Steve|url=https://books.google.com/books?id=WevHvt6Tr8kC|title=Mushrooms of the Pacific Northwest|last2=Ammirati|first2=Joe|publisher=Timber Press|year=2009|isbn=978-0-88192-935-5|series=Timber Press Field Guides|location=Portland, OR|page=179}} The cap's odor and taste are mild or mealy.
The spores are brown, elliptical, and smooth, producing a brown spore print. Some experts divide A. pediades into several species, mainly by habitat and microscopic features, such as spore size. It is recognized by the large, slightly compressed basidiospores which have a large central germ pore, 4-spored basidia, subcapitate cheilocystidia and, rarely, the development of pleurocystidia.Bókaútgàfa Menningarsjóds [https://books.google.com/books?id=hLBKAAAAYAAJ&q=+compressed+basidiospores Timarit um islenzka grasafrædi], ed. 7–12, pg. 5, Reykjavík (1984)

Other similar species include Agrocybe praecox and A. putaminum. Hypholoma tuberosum is also similar.
Habitat
It typically can be found on lawns and other types of grassland,{{cite web |title=Agrocybe pediades - GBIF Portal |url=http://data.gbif.org/species/14369805 |access-date=2009-11-01 |publisher=Global Biodiversity Information Facility}} but can also grow on mulch containing horse manure. It appears year-round in North America.
Uses
This species is edible, but it could be confused with poisonous species, including one of the genus Hebeloma{{cite book |last1=Miller Jr. |first1=Orson K. |author-link=Orson K. Miller Jr. |title=North American Mushrooms: A Field Guide to Edible and Inedible Fungi |last2=Miller |first2=Hope H. |publisher=FalconGuide |year=2006 |isbn=978-0-7627-3109-1 |location=Guilford, CN |page=271}} and various little brown mushrooms. Some field guides just list it as inedible or say that it is not worthwhile.
