However, A. Amanita inopinata has a larger cap entirely covered with the thick, cottony, pale gray-brown felt which disrupts into very prominent darker pyramidal warts (Reid 1987); Amanita pruittii has a very small to very large cap (2.0 – 15.0 cm) and much longer and wider stipe (3.0 – 15.0 × 6.0 – 4.0 cm), appears to be much stronger than A. albicarnosa (Tulloss et al. 2014); Amanita quitensis (Crous et al. 2018) was firstly reported from Ecuador and this species appears under thick, dense, hard, scale-shaped warts on its white pileus, as well as the globose or rarely subglobose basidiospores (6.0 – 12.0 × 6.5 – 9.5 μm, Q = 1.04 μm); Amanita singer, originally described from Argentina, has the white to greyish white pileus, the rather inconspicuous volva remnants on the cap and the particular salmon-colored gills (Bas 1969).	en	Liu, Yuan S., Kumla, Jaturong, Suwannarach, Nakarin, Sysouphanthong, Phongeun, Lumyong, Saisamorn (2022): Three species of Amanita section Lepidella (Amanitaceae, Agaricales) from northern Thailand.

03D2031BFFAFCC5CD38532FCFE0BDD13.taxon	discussion	Remarks: Morphologically, Amanita aureofloccosa is unique among congeners by having a pulverulent, bright orange-yellow volva remnant on its pileus, a slender stipe covered by orange-yellow floccose scales, a globose to subglobose, amyloid basidiospore and the lacking clamps in all parts of basidiomata. According to the original literature (Bas 1969), the basidiospores size of A. aureofloccosa was described as 7 – 8.5 × 6.5 – 8.5 μm, but Wartcow et al. (2015) re-examined the lectotype (BR 2229) and additional material from Ghana (K 173243), and amended the basidiospores size to (6.5 –) 6.8 – 10.5 (– 10.8) × (6.5 –) 6.8 – 10.2 (– 10.5) μm, of which the results are similar to Thai material.

03D2031BFFA0CC5DD385367EFAE6D96A.taxon	discussion	Remarks: Amanita manicata is characterized by its yellowish brown to pale tawny brown pileus covering with floccoso-verrucose to felty squamules; margin appendiculates with large floccose fragments which hang down up to 2 cm; the cylindrical stipe covering with tawny brown floccoso-squamose which becomes more intense and thicker as upwards; the cream to whitish or pinkish tint lamellae; the subglobose and amyloid basidiospores (7.0 – 8.5 × 5.5 – 8.0 μm), as well as the present clamps. In our phylogenetic analysis, A. manicata closed to A. flavofloccosa Nagas. & Hongo, A. foetidissima Reid & Eicker and A. nauseosa (Wakef.) Reid and they formed a sister group (Figure 2). Meanwhile, these four species share the similar appearance and color tone of basidioma, as well as the intense and unpleasant odor, which make people easily confuse for these species in the field. However, A. flavofloccosa can be distinguished from A. manicata by its yellow-brown to orange-yellow pileus and white, pinkish to yellowish lamellae (Cui et al. 2018). Amanita foetidissima, originally reported from South Africa (Reid & Eicker 1991), has a pale creamy buff to buff pileus, oval to subglobose (7.0 – 9.0 × 6.2 – 8.0 μm), to broadly ellipsoid (9.0 – 10.0 × 6.0 – 6.2 μm) basidiospores, as well as the larger basidia (50.0 – 52.0 × 9.0 – 9.5 μm). Although A. nauseosa is very similar to A. manicata, it has a buff, or reddish-tinged to pale ochraceous buff surface and the greater basidiospores (7.0 – 9.0 × 6.5 – 8.0 μm) (Bas 1969).	en	Liu, Yuan S., Kumla, Jaturong, Suwannarach, Nakarin, Sysouphanthong, Phongeun, Lumyong, Saisamorn (2022): Three species of Amanita section Lepidella (Amanitaceae, Agaricales) from northern Thailand.
