Editing Pholiota "sp-IN01" (section)

== Description ==


Caps yellow, yellow-orange, brownish-yellow, brownish-orange, or at times with reddish tones. The cap texture is most often presenting as scaley but sometimes appearing as fibrous scales more dense at the center of the cap. Described by user thefungiproject as "Cap scurfy with orange scales and inrolled margin." Cap size ranges from slightly less than 1 cm to 4cm wide as measured or pictured with a scale [https://www.inaturalist.org/observations/31611619][https://www.inaturalist.org/observations/162793478] [https://www.inaturalist.org/observations/241801885] [https://www.inaturalist.org/observations/239558049] [https://www.inaturalist.org/observations/187587640] [https://www.inaturalist.org/observations/187412220] [https://www.inaturalist.org/observations/170043547] [https://www.inaturalist.org/observations/183311960] [https://www.inaturalist.org/observations/25900727] Margin sometimes appendiculate with yellow fibrous material. The cap can on occasion appear distinctly umbonate [https://www.inaturalist.org/observations/98418675] Stems often thin and with yellow scales when fresh and a ring zone where the cap once met the stem while young. iNaturalist user thefungiproject describes stems as "Stipe also scurfy with orange scales (lesser than cap)." [https://www.inaturalist.org/observations/172599280] One measurement of stem length and width of 2-4mm wide and 2.5-4.5cm long [https://www.inaturalist.org/observations/25900727] Gills are pale yellow in color with a crenulate gill edge. Mycelium is pale yellowish to whitish. The odor is described as indistinct [https://www.inaturalist.org/observations/11195415] , of anise [https://www.inaturalist.org/observations/180101799] , pleasant [https://www.inaturalist.org/observations/25900727] , or none [https://www.inaturalist.org/observations/190371916] [https://www.inaturalist.org/observations/190371916]. Taste is described as mildly bitter [https://www.inaturalist.org/observations/190371916], bitter [https://www.inaturalist.org/observations/190371916] [https://www.inaturalist.org/observations/25900727] or very bitter [https://www.inaturalist.org/observations/172599280]. KoH reaction is pictured as negative [https://www.inaturalist.org/observations/170504468] but one user reports a positive reaction but has no photos [https://www.inaturalist.org/observations/183311960]. User mandymushii has photos detailing a yellow UV reaction  on the stem, gills, and cap with 365nm UV light [https://www.inaturalist.org/observations/183311960] while user mitchellpittsley demonstrates a whitish UV reaction on the gills with 396nm UV light [https://www.inaturalist.org/observations/171328086]. 

Spore print is brown. User heelsplitter measured spores and viewed other microscopic structures with Piximetre and found: "Clamp connections present in the pileipellis and in the lamellar trama. Basidia 2-sterigmate. Cheilocystidia capitate and yellow in NH4OH (chrysocystidia?). Pleurocystidia seemed to be absent. Spore measurements from Piximetre: (6.6) 7.1 – 8.9 (9.9) × (4) 4.3 – 5.3 (5.9) µm, Q = (1.5) 1.54 – 1.79 (1.8); N = 30, Me = 7.8 × 4.7 µm; Qe = 1.7

Three other observations featured microscopy but included no measurements [https://www.inaturalist.org/observations/80944687] [https://www.inaturalist.org/observations/165434348] [https://www.inaturalist.org/observations/25900727]

Pleuroflammula multifolia : User pinonbistro writes "Compare to MN206909 Pf. multifolia, the reference sequence for the taxon chosen by Irja Saar of UNITE. Pf. subsulphurea sequences on GenBank appear to be mislabeled. It may be that the two are synonyms in which case Pf. multifolia is the older name.

An alignment of ITS sequences indicates that Pholiota "sp-IN01"=Pf. multifolia" [https://www.inaturalist.org/observations/57395631]

Sequences of Pholiota "sp-IN01" are also at times labelled as Pholiota tuberculosa, Pleuroflammula tuberculosa, Pholiota subsulphurea, or Pleuroflammula subsulphurea on iNaturalist.
