Amanita manicata Pegler, Kew Bull., Addit. Ser.

Figure 1d Habitat: Solitary to scattered in black sand at berm of beach, on soil in grass or forest, in composted woodchips, April to October. Distribution: Known from Dominican Republic, New Zealand, Sri Lanka, Thailand, and the USA (Hawaiian Islands) (Petch 1910; Pegler 1986; Hemmes & Desjardin 2008). Specimens examined: THAILAND.

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).Published as part of Liu, Yuan S., Kumla, Jaturong, Suwannarach, Nakarin, Sysouphanthong, Phongeun & Lumyong, Saisamorn, 2022, Three species of Amanita section Lepidella (Amanitaceae, Agaricales) from northern Thailand, pp. 16-28 in Phytotaxa 570 (1) on pages 24-25, DOI: 10.11646/phytotaxa.570.1.2, http://zenodo.org/record/752986

No full textVolvariella pulla E.F. Malysheva & A.V. Alexandrova, Phytotaxa 408 (4): 247 (2019) (Figures 4 & 5) MycoBank MB 831060, Faces of Fungi 08024 Description:— Basidiome large. Pileus 70 mm diam., plano-convex with a low broad umbo, brownish grey (6E2) with slightly darker color at the center, dull, dry, non-hygrophanous, with fibrillose to appressed-squamulose surface; margin decurved to straight, crenulate; context light yellow (4A5), soft. Lamellae free, ventricose, close, moderately thin, soft, pale orange (6A3) to brownish orange (6C8) and turning light brown (6D8) with age; edge finely fimbriate, concolorous with faces; lamellulae present, very variable in length, mostly in one tier. Stipe 65 × 4 mm, central, terete, tapered from the base to apex, solid, dark brown (6F4–5), slightly paler near the base, entirely pubescent; context light yellow (4A5); annulus absent. Volva rather thick, mostly free, saccate, fragile, greyish brown (6D3). Spore print pinkish (7A2). Odor indistinct. Taste mild. Basidiospores [60,1,1] (5.5)6–7–7.5(8.0) × 4–4.4–4.5(5) µm (Q = 1.2–1.8, Q* = 1.5), broadly ellipsoid to ellipsoid, oblong, ovoid, thickened wall, hyaline in 5% KOH. Basidia [30,1,1] (16)17–18.1–19(19.5) × (7)7.5–8– 8.5(9) µm (Q = 1.8–2.8, Q* = 2.3), tetrasporic, narrowly to broadly clavate, hyaline in 5% KOH. Cheilocystidia [20,1,1] (24)29–37.5–56(87) × (9)11–12.1–13(17) µm (Q = 1.6–6.4, Q* = 2.8), abundant, varied in size and shape, narrowly to broadly utriform, broadly lageniform, broadly fusiform, lecythiform, thin-walled, hyaline and colorless in 5% KOH. Pleurocystidia [20,1,1] (25)29–36.5–44(56) × (6)12–16.6–19(32) µm (Q = 1.5–4, Q* = 2.2), ellipsoid, obpyriform, utriform, broadly fusiform, lageniform, mostly thin-walled, hyaline in 5% KOH. Hymenophoral trama inverse, made up of thin-walled hyaline hyphae. Pileipellis a trichoderm; terminal elements with light brown (6D5) intracellular pigment, slightly darker on the swollen ends, [20,1,1] 77–177 × 11–31 µm. Stipitipellis a cutis; terminal elements with light brown (6D8) intracellular pigment [20,1,1] 75–162 × 8–15 µm, forming hairs. Clamp connections not seen in any part. Habitat and distribution:—Solitary, on the soil among grasses partly covered with litter. First described from Gia Lai Province in Vietnam. Now it is also known from northern Thailand. Specimen examined:— THAILAND. Chiang Rai Province: Mae Fah Luang University, 20.0449° N, 99.8943° E, lawn, 27 September 2018, P. Sysouphanthong, MFLU 19-1534 (GenBank MT 074696 - ITS). Notes:—According to the protologue, Volvariella pulla has medium to large basidiomes, with greyish brown or ash brown pileus and colored volva; the stipe is beige, ochraceous or greyish brown at base (Malysheva et al. 2019). The specimen from Thailand is morphologically similar to the holotype. However, the stipe was darker (dark brown). This difference might be due to the more advanced maturity or drier condition of the specimen, which was photographed and described after getting back to the laboratory (Figure 4). Volvariella pulla is recorded for the first time from Thailand after it was described from Vietnam in 2019 (Malysheva et al. 2019). Although V. pulla is morphologically most similar to V. rostricystidiata and V. volvacea, it is phylogenetically most closely related to V. guttulosa E.F. Malysheva & A.V. Alexandrova (2019: 242) and V. niveosulcata E.F. Malysheva & A.V. Alexandrova (2019: 240) (Figure 1).Published as part of Niego, Allen Grace T., Sysouphanthong, Phongeun, Thongklang, Naritsada, Hyde, Kevin D., Phonemany, Monthien, Phookamsak, Rungtiwa & Raspé, Olivier, 2021, A new species of Volvariella and the first record of Volvariella pulla (Agaricales: incertae sedis) from Thailand, pp. 237-250 in Phytotaxa 480 (3) on pages 244-246, DOI: 10.11646/phytotaxa.480.3.3, http://zenodo.org/record/541688
