Pileus 55–85 mm diam., plano-convex, greyish brown (6E3) with darker pigment at the center becoming lighter towards the margin, dull, dry, non-hygrophanous, matted-fibrillose, appressedsquamulose surface; margin decurved to plane, crenulate; context light yellow, unchanging when cut, with soft consistency.

Sysouphanthong, MFLU 19-1531 (GenBank MT 074695 - ITS, MT 078696 - nrLSU).</p> <p>Notes:— Volvariella rostricystidiata has a smooth to slightly pubescent solid stipe whereas V. pulla has an entirely pubescent stipe (Malysheva et al. 2019 and this study). Moreover, the cheilocystidia of V. rostricystidiata are mostly clavate to broadly clavate and consistently show a rostrate apex (Figure 3), whereas those of V. pulla are extremely variable in size and shape, ventricose-lageniform, broadly fusiform, spatula-shaped, a small proportion are utriform, sometimes with subglobose or bifurcated apex as described by Malysheva et. al. (2019). In the phylogenetic tree analyses V. pulla belonged in a different clade than V. rostricystidiata. The cheilocystidia of V. rostricystidiata are somewhat similar to those of V. caesiotincta P.D. Orton (1974: 319), except that the latter has more variable cheilocystidia, which are clavate, fusoid, less frequently subvesiculose or utriform, mostly with a rostrum that is often abruptly connected with a basal part and often irregular, branched to occasionally subcoralloid (Antonín 2012). In our phylogeny, V. rostricystidiata was closely related to V. nivea. However, it is morphologically quite different since the latter has white basidiomes (Li et al. 2009).</p> <p>There are other species morphologically similar to Volvariella rostricystidiata, all having a greyish to greyish brown pileus but all differing from V. rostricystidiata in other features. The American Volvariella bakeri (Murrill 1911: 281) Shaffer (1957: 557) is characterized by a dark fuliginous pileus, becoming lighter with age, up to 100 mm in diameter, and larger basidiospores 6.9–9.3 × 4.6–6.9 µm (Shaffer 1957, Wartchow 2009). Volvariella morozovae E.F. Malysheva &amp; A.V. Alexandrova (2017: 343) from Vietnam has smaller (20–45 mm diam.), more delicate basidiomes, a hairy pileus and volva, and mostly ellipsoid or lacrymoid basidiospores (Crous et al. 2017). Volvariella murinella (Quélet 1883: 391) M.M. Moser (1953: 110) known from Europe produces small basidiomes (10–55 mm) that are whitish when young (Boekhout 1986). Volvariella taylorii (Berk. &amp; Broome 1854: 398) Singer (1951: 401) has smaller (20–50 mm diam.), shiny and often subviscid basidiomes (Boekhout 1986, Wartchow 2009, Le &amp; Chu 2018).</p> </div>	https://treatment.plazi.org/id/03E487A7FF9FFFE3FF2878D7294BF8CB	Public Domain	No known copyright restrictions apply.

Sysouphanthong, MFLU 19-1534 (GenBank MT 074696 - ITS).</p> <p>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).</p> <p>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 &amp; A.V. Alexandrova (2019: 242) and V. niveosulcata E.F. Malysheva &amp; A.V.
