Summary:
Floccularia albolanaripes is identified by 1) medium size, 2) a yellow cap, the center of which becomes brown, 3) adnexed or notched gills that are creamy to pale yellow, 4) soft cottony scales on a dry white stem, 5) a fibrous woolly ring, 6) a mild odor, 7) a white spore deposit, and 8) inamyloid spores. Smith(15) says it is "not uncommon during the fall rainy season in the Pacific Northwest".

Cap:
5-12cm across, convex or slightly umbonate to flat; yellow to golden yellow, more often brown at center and yellow at margin; moist or slightly viscid with flattened fibrils or scales that darken when old, veil remnants may be on cap margin but no warts on the cap, (Arora), 4-10cm across, obtuse to subconic or convex when young, becoming nearly flat or with slight obtuse umbo, margin becoming slightly recurved (upcurved) at times; 'bright yellow at first ("lemon-chrome"), the margin whitish, disc gradually becoming darker ("cinnamon-brown" to "bister") and the margin bright yellow, the scales also darkening in age (near "cinnamon-brown")'; "slightly viscid at first but soon dry, innately fibrillose-streaked and in age becoming slightly scaly toward the margin, margin at first often appendiculate from veil remnants", (Smith(15))

Flesh:
white or tinged yellow, (Arora), thick, tapered evenly to margin, firm; white or with yellowish zone near surface, (Smith(15))

Gills:
adnexed or notched, close; white to pale yellow, (Arora), "sinuate to adnexed, close to subdistant, broad"; ''white when young but soon yellowish, finally rather deep yellow, ("yellow-ocher")''; "edges becoming serrated or eroded", (Smith(15))

Stem:
2-8cm x 1-2.5cm, equal or widening downward; white above the ring, with soft cottony scales in lower part, the scales white then yellow-tipped or brown-tipped when old, (Arora), 2-6(8)cm x 0.9-1.6cm, equal or nearly so, stuffed with compact white pith; whitish or yellowish above ring, below ring "scales white at first but soon yellowish and finally with brownish tips"; silky and smooth above ring, lower half sheathed by ragged torn fibrillose-scaly veil remnants, scales often in concentric zones, (Smith(15))

Veil:
ring cottony, white, ragged, fragile, superior, (Arora), ring median, submembranous to fibrillose, terminating the sheath that covers the lower stem, (Smith(15))

Odor:
mild (Arora), none (Smith(15))

Taste:
none (Smith(15))

Microscopic spores:
spores 5-8 x 3-5 microns, elliptic, smooth, weakly amyloid, (Arora), spores 6-8 x 4-4.5 microns, elliptic to somewhat drop-shaped with central oil droplet, smooth, inamyloid; basidia 4-spored, 26-30 x 5-7 microns; pleurocystidia and cheilocystidia none; gill trama parallel to subparallel, subhymenium very narrow and not distinctive; cap trama homogeneous, hyphae of cap cuticle radially arranged, 5-8 microns wide, and occasionally with clamp connections, not gelatinous in KOH, (Smith(15))

Spore deposit:
white (Arora)

Notes:
It has been noted specifically for OR, CA, (Murrill(9)), and BC (Schalkwijk-Barendsen). It has been reported from WA by Andrew Parker, pers. comm., and in Mitchel(1) from CO (a white variant) and NM. There are collections from BC and OR at the University of British Columbia and from WA and OR at the University of Washington.
