Remarks (internal):Lepiota metulispora is characterized by small basidiomata, radially sulcate striate pileus with brownish yellow to ochraceous-buff squamules and penguin-shaped spores. Type study shows that basidiospores of the type (average 14.5 x 4.8 µm) are relatively smaller and broader than those in Pegler (1972) (15.7 x 4.3 µm), and terminal elements of pileus covering are apically attenuate but not rounded obtuse.
Lepiota thrombophora differs from L. metulispora by dark brown squamules and the rarely occurring short clavate elements between elements in the pileus covering.

? Lepiota clypeolaria var. metulispora (Berk. & Broome) Babos, Annls hist.-nat. Mus. natn. hung. 53:198, 1961 (as metulaespora).
Basidiomata (fig. 2A). Pileus 2-3 cm diam, convex, more or less umbonate, surface covered with small, appressed, ochraceous buff squamules on a whitish background, brownish yellow at the disk; margin radially sulcate striate half-way to center. Lamellae free, whitish, crowded with lamellulae of two lengths. Stipe 3-4.5 x 0.2-0.3 cm, subcylindrical, hollow, whitish and glabrous at the apical part, lemon yellow to brown at lower part, with white to cream flocculose squamules, inflated at base. Annulus whitish, membranous, evanescent.
Basidiospores (fig. 2B) [60/3/3] (12.0)13.0-17.0 x (3.5)4.0-5.5 µm [Q = (2.60)2.70-3.30(3.75), Q = 2.92 ± 0.18], penguin-shaped with straight abaxial side and a suprahilar depression in side view, without germ pore, fusiform to subcylindrical in frontal view; hyaline, smooth, slightly thick-walled, strongly dextrinoid, congophilic, not metachromatic in cresyl blue, with guttules. Basidia 15-35 x 7-12 µm, clavate, four-spored, rarely intermixed two-spored. Lamella edge sterile. Cheilocystidia (fig. 2C) 19-34 x 8-11 µm, narrowly clavate to fusiform, sometimes utriform and subcylindrical, walls smooth, thin, hyaline in KOH, congophilic. Pleurocystidia absent. Pileus covering (fig. 2D) a trichodermial palisade of elongate, apically attenuate terminal elements, 75-218 x 7-13 µm, often between with some short elements; pigment pale yellow brown, parietal and intracellular in upper part, sometimes in basal part of elements also finely encrusting. Clamp connections common.
Type study. - Basidiospores (fig. 3A) [20/1/1] 13.5-15.5 x 4.5-5.5 µm [Q = (2.55) 2.73-3.33(3.50), Q = 2.83 ± 0.24], penguin-shaped with straight abaxial side and a suprahilar depression in side view, without germ pore, fusiform in frontal view; hyaline, smooth, slightly thick-walled, strongly dextrinoid, congophilic, not metachromatic in cresyl blue, with guttules. Basidia 20-29 x 7-10 µm, clavate, four-spored. Cheilocystidia unknown. Pileus covering (fig. 3B) a trichodermial palisade of elongate, apically attenuate terminal elements 95-230 x 7-12 µm, between often with some short elements, with pale yellow brown pigment, sometimes in basal part also encrusted with a fine brown pigment. Clamp connections common.
