Gymnopilus cyanopalmicola

The fruit bodies of Gymnopilus cyanopalmicola have yellow, convex to plane caps 5 to 10 cm (2.0 to 3.9 in) in diameter, with fibrillose scales that are erect near the center and appressed near the margin. The gills are crowded, ventricose, with adnate to decurrent gill attachment. The stem is 40–210 mm (1.6–8.3 in) long by 4–21 mm (0.2–0.8 in) thick, cylindrical, fibrillose, tapering at the base in larger fruit bodies. It is colored yellowish white, and turns purple, dark reddish or dark brown when bruised or dried. The stipe has a conspicuous but soon fading membranous yellowish-white annulus. The pileus trama is light yellow, similar to the color of the cap. The odor is fungal. The verrucose spores are ellipsoid to oblong, amygdaliform, thick walled, and lack a germ pore and plague, but have a superhilar depression. They typically measure 8.0 - 8.8 (-11.2) x by 5–6 (6 - 8) μm. They are dextrinoid, orange-brown in KOH, not metachromatic, and have cyanophilic ornamentation. Basidia are clear to yellowish, four spored, 26.4 - 37.5 x 6.4 - 7.7 μm, cylindrical to clavate, constricted in the middle, with sterigmata 3.2–4.8 μm long. The bases of the basidia have clamp connections. …
