Pileus (Cap): 18-53 mm broad, convex, plane-convex to plane, finally uplifted, dry, squarrose to appresed-squamulose, especially on the disc, small scales of fibrilles reddish brown to purple, back ground color to orange yellowish, light reddish yellow or purple yellow, scales sometimes evanescent with age, margin entire, with ferruginous-brownarachnoid remains of the partial veil; pileus surface staining green when bruised.
Lamellae (Gills): Adnate with or without a desurrent tooth to subdecurrent, close, broad to subventricose, yellow to ferruginous orange or ferruginous brown when mature, edge entire to subfarinaceous, yellowish. Stipe (Stem): 10-30 x 2-6 (-9) mm, central to excentric, equal, slightly broader at the base, folded like an "L" or suberect, fibrillose, grayish white with purple or reddish stains, solid to hollow. veil arachnoid, ferruginous brown, forming an inconspicuous apical fibrillose annulus. context whitish to yellow whitish. Microscopic features: Spores ferruginous brown in mass, 6-8 x 4-4.8um, ellipsoid, verruculose germ pore absent, yellowish-ornage-brown, with refringent context, dextrinoid. Basidia 19.2-24 x 5.6 - 7.2 um, bi-or tetrasporic, clavate or subcylindric, some with central construction, with granulose, yellowish grey content, sterigmata 1.6-4um long. pleurocystidia absent. cheilocystidia 16.8 - 28 x 5.6-7.8 um, apex 3.2-6.4um in diameter, flask shaped, subcapitate or capitate, some with a long neck, with granulose, yellowish grey contents, gill trama subparrallel. pileus trama interwovem, hyphea 4-24um broad, septate, with thin wall. cuticle with hyphea 4-14.4um braod, postrate, yellowish, exept for fibrils, which are yellow -orange-brown, some with distinct incrustations. pileocystidia absent. caulocystidia 24-68 x 3.6-12um, apex 4.8-8um broad, cylindric, ventricose cylindric subcapitate or capitate, some flask shaped or clavate, hyaline or rarely yellowish grey or yellowish orange, present only in the stipe apex, in tufts, very common. clam connections present. laticiferous hyphae present. a yellowish pigment is isolved when mounted in KOH.
Season: June through November.
Habitat and Distribution: Substrate conifer, original collection on pine-wood of unknown origen studied int eh state of Jalisco, Mexico.
Bruising: Green or blue bruising at the base and on the pileus, green spots on the pileus likely.
Other Notes: Odor farinaceous and sweet, taste bitter. Koh staining pileus with olivaceous-green spots or purple margins; on the lamellae yellowish brown; on the stipe purple brown to almost black and ont he context greenish yellow. G. subpurpuratus is charecterized by the small fibrollise-scales on the disc, the greenish stains and the veil forming an annular zone. The green staining suggests that the species belongs the G. luteofolius/aeruginosus clade. It can be differentiated between G. aeruginosus by the lack of yellow and reddish spots, less scaly and lacks pleurocystidia and has a different type of caulocystidia.
