Summary:
Calocybe carnea is recognized by its pinkish cap and stem, crowded white gills, and white spore print. Rugosomyces carneus (Bull.: Fr.) Bon was the current name in the online Species Fungorum, accessed March 24, 2014, but Rugosomyces is synonymized with Calocybe in the Tenth Edition of Dictionary of the Fungi, and the current name in MycoBank was still Calocybe carnea. The description is derived from Arora(1) except where noted.

Cap:
1.5-4cm across, convex to flat or slightly umbonate; usually pinkish to pinkish brown, but varying to dark reddish or fading to pale tan; dry, more or less smooth

Flesh:
thin; whitish

Gills:
adnate to slightly decurrent or notched, crowded, narrow; white, (Arora), adnexed, close, crowded, with subgills; white, (Schalkwijk-Barendsen), virtually free, (Lincoff(1))

Stem:
1.5-4cm x 0.2-0.5cm, equal; colored more or less as cap; smooth or finely fibrillose, (Arora), sturdy, "color of the cap in the top half, streaked, white base, buried in moss and enlarging toward base to club shape", (Schalkwijk-Barendsen), tough, almost cartilaginous, narrowing toward the base, sometimes pruinose at the top, (Lincoff), finely longitudinally fibrillose, top with a zone of white powder that is often indistinct, base sometimes white-tomentose, (Breitenbach)

Taste:
not distinctive

Microscopic spores:
spores 4-6 x 2-3 microns, elliptic, smooth; basidia have siderophilous granules, (Arora), spores 4.7-6.4 x 2.1-3.2 microns, elliptic to cylindric-elliptic, smooth, iodine negative, with droplets; basidia 4-spored, 13-18 x 3.5-5 microns, cylindric-clavate, with basal clamp, with siderophilous granules; pleurocystidia and cheilocystidia not seen; cap cuticle of irregular hyphae 3.5-7 microns across, uppermost layer with brown epimembranal pigmentation, septa with clamp connections, (Breitenbach)

Spore deposit:
white

Notes:
It has been recorded and photographed from WA by Michael Beug and by Ben Woo. There is a collection by Paul Kroeger from BC at the University of British Columbia. It also occurs in AB and is widespread in North America (Schalkwijk-Barendsen).
