Hygrocybe flavescens

(Kauffman) Singer

YELLOW WAXY CAP

CAP: 2–8 cm across, convex to plane with a small umbo, margin becoming uneven, mature specimens often wavy. Pale lemon yellow to bright yellow or yellowish orange, fading in age. Surface moist to viscid when wet, often dry in older specimens or in dry weather, and often with debris stuck to the cap. GILLS: Notched to narrowly attached, subdistant, narrow to broad, soft, greasy. Off-white to pale yellow when young, staying pale yellow or becoming darker yellow to yellowish orange in age. STIPE: 3–5 cm long, 0.5–1.5 cm thick, more or less equal, usually developing a longitudinal groove in age. Yellow, pale lemon yellow or yellowish orange. Surface fibrous to smooth, moist to slippery when wet, quickly drying out. FLESH: Creamy white to pale yellow, stipe stuffed when young, becoming hollow. ODOR: Indistinct. TASTE: Indistinct. KOH: Bleaching cap pigment. SPORE DEPOSIT: White. MICROSCOPY: Spores 7.5–9 × 4–5 µm, averaging 8.4 × 4.3 µm, ellipsoid, smooth, inamyloid, colorless.

ECOLOGY: Solitary, scattered, or in small clusters in humus and duff, most often under redwood, but can be found in many forest types. Common throughout our range. Fruiting from late fall into spring.

EDIBILITY: Reportedly edible.

COMMENTS: This common waxy cap is best identified by the viscid, convex to plane, yellow to yellow-orange cap without any red tones and the whitish to yellow gills and stipe. Some authors consider H. chlorophana to be a separate species, distinguished by a viscid stipe and more orange cap. We consider these more orange and slightly viscid-stalked specimens to be within the range of variation for H. flavescens. H. acutoconica is similar, but has a more peaked-conical, yellow-orange to reddish cap and a fibrous stipe. Faded fruitbodies of the much rarer H. virescens can be similar, but have dry caps and usually at least faint traces of greenish hues.
