Description:Macrolepiota dolichaula (Berk. & Broome) Pegler & R.W. Rayner, Kew Bull. 23: 365 (1969). Fig. 1
Basidiomata medium to large with long stipe. Pileus ≤13.5 cm diam., fleshy, convex to plano-convex, white (5Y9/2), with inwardly projected margins, umbonate, covered with minute, pallid, yellowish brown (10YR5/6) squamules, crowded at centre, become minute and sparse towards margins; disc yellowish brown (10YR5/6); margins rough, fragile at maturity; context thick and white (5Y9/2). Lamellae free, crowded, white (5Y9/2) when young, becoming off white to cream (2.5Y8/4) at maturity. Lamellulae few in general. Stipe ≤26 cm long, gradually tapering towards the apex, diam. 0.5 cm towards the pileus and ≤1.3 cm towards the base, farinose, mostly glabrous, off-white to cream (2.5Y8/4), scabrous just below the annulus, with brown (10YR7/6) scales; base bulbous, ≤2 cm in diam. Annulus ascending, whitish (2.5Y8/4), superior, membranous, moveable. Odor and taste not recorded.
Basidiospores [50/1/1] 9.4-15.6 x 7.5-11.3 µm (average = 12.5 x 9.4 µm), avQ = 1.33, ovoid to broadly ellipsoid, ellipsoid, hyaline in 5% KOH, reddish brown in Melzer’s reagent, with a germ pore on the rounded apex with a hyaline cap; apiculus 1-1.5 µm high. Basidia 29-39.6 x 9.9-14.4 µm, clavate to subclavate, thin-walled, hyaline in 5% KOH, 4-spored. Pleurocystidia absent. Cheilocystidia 18.4-28.4 x 7.1-12.8 µm, clavate, thin walled, hyaline. Squamules on pileus consisting of cylindric to subcylindric, branched, clampless hyphae, 3-10 µm in diam., terminal elements cylindric to slightly attenuating towards the tip, hyaline to yellowish brown vacuolar pigment. Clamp connections occasional at basidial bases.
