Species Information

Pholiota aurivella group is recognized by yellow to orange viscid cap with large spot-like darker scales, scaly stem, and brown spore deposit; of the Pholiota aurivella group, 90% in PNW are P. limonella and most of the rest P. aurivella, while P. adiposa is almost unknown from North America, differentiation is by spore size; to complicate matters, Pholiota aurivella (Batsch: Fr.) Kummer non sensu Batsch and Pholiota adiposa sensu Fr. are both given by Breitenbach(4) as synonyms of Pholiota cerifera (P. Karst.) P. Karst., and they give P. adiposa (Batsch: Fr.) P. Kumm. sensu auct. non Fr. as a synonym of Pholiota jahnii Tjall. & Bas; Smith(3) examined collections from BC, WA, OR, ID, and also ON, QC, AK, CA, CO, ME, MI, NC, NM, TN, UT, Netherlands, Switzerland, United Kingdom, also reported from IL
4-15cm across, "bell-shaped to convex with a broad umbo"; ocher-orange to tawny; sticky to slimy with large flattened spot-like scales that may disappear or become somewhat sticky when wet, (Phillips), 4-16cm across, bell-shaped to convex, often broadly umbonate; when young ochraceous orange to tawny, when mature more uniformly tawny; "at first covered with large appressed spot-like scales which may disappear and when wet may become more or less gelatinous, cuticle viscid or gelatinous", (Smith)
firm; yellow, (Phillips, Smith)
adnate, close, moderately broad; pale yellowish becoming tawny brown, (Phillips), "adnate, sinuate-adnate, or emarginate", close; "pale yellowish, becoming ferruginous brown", (Smith)
5-8cm x 0.5-1.5cm, central or off-center, solid; yellowish to yellow-brown; dry, cottony above the ring, hairy and with downcurved scales toward the base, (Phillips), 5-8cm x 0.5-1.5cm, equal, central or eccentric [off-center], solid; yellowish or yellowish brown; dry, floccose above the ring, fibrillose below ring and increasingly scaly downward, the scales fibrillose and recurved [upcurved], (Smith)
white partial veil leaves evanescent [fleeting] ring or zone on upper stem, (Phillips)
sweet (Phillips), mild (Miller)
slight (Phillips)
Microscopic spores:
spores 7-9.5(11) x 4.5-6 microns, broadly elliptic in face view, in side view broadly elliptic to obscurely bean-shaped, smooth, germ pore distinct but apex not truly truncate, color in KOH dull tawny, in Melzer's reagent reddish cinnamon, wall about 0.25 microns thick; basidia 4-spored, 24-28(30) microns, colorless to yellowish in KOH and Melzer's reagent, narrowly clavate, some with colorless refractive amorphous particles, some with rusty brown content in KOH (clearing somewhat on standing), and some colorless and homogeneous; pleurocystidia 30-45 x 4-7 microns, mostly fusoid or branched once or twice near apex (rarely appearing as having 3-4 coarse sterigmata, 3-4 microns at base), content colorless to partially filled with solidified colloidal material or with refractive particles dark brown in Melzer's reagent (but not with characteristic refractive inclusion as in chrysocystidia), cheilocystidia 26-35 x 5-10 microns, subfusoid with obtuse apex to fusoid-ventricose and obtuse, or versiform, wall at times thick enough to show as double line; caulocystidia none; clamp connections present, (Smith), spores 8.5-10.2 x 5-6.5 microns, (Scates(2) following Farr et al.)
Spore deposit:
rusty brownish (Phillips)
