Hygrophorus aff. atropurpureus is currently known from a single collection with suboptimal material; no obvious morphological differences from H. atropurpureus have been observed and a formal comparison will be deferred until additional specimens become available.</p></div>	https://treatment.plazi.org/id/6CE43A965D2B5D1491E37910B74046BE	Public Domain	No known copyright restrictions apply.

Its basidiomata are slender, with a pileus 2–7 cm diam. and a stipe measuring 5.5–10 × 0.4–1 cm. The pileus exhibits a greyish-brown disc and the lamellae are distant (25–35 full lamellae per pileus). A distinctive odour reminiscent of H. cossus (similar to the scent of goat moth larvae, Cossus cossus) is also characteristic. Microscopically, it produces ellipsoid basidiospores measuring 8–10 × 5–6 μm and the pileipellis is an ixotrichoderm, composed of subglobose, cylindrical or clavate elements that are insoluble in 5 % KOH. Ecologically, this species grows scattered in broadleaf forests, occasionally forming arcs or fairy rings and is likely associated with Quercus guyavaefolia . It is currently known only from the subalpine zone (2000–3500 m) of south-western China (Wang et al. 2020, 2023; this study).</p></div>	https://treatment.plazi.org/id/E06BAF601F4A52D79B9F73D5D3C3A133	Public Domain	No known copyright restrictions apply.

This species is distinguished by its white pileus and cream-coloured lamellae that develop pale ochraceous-pink tones at maturity. It produces ellipsoid to oblong, occasionally cylindrical basidiospores. Spore dimensions vary geographically: Chinese specimens measure 8–9 × 4–5 μm (Q = 1.6–2.0), European specimens 8–10 × 5–6 μm (Q = 1.49–1.96) and cylindrical forms 10–12.6 × 3–4 μm (Q = 2.5–4.25). Ecologically, it shows a wide elevational range (100–3500 m), occurring at low to middle elevations in Europe and north China (Heilongjiang, Inner Mongolia, Shanxi) and extends to high-altitude regions in southwest China (Sichuan) (Larsson and Jacobsson 2004; Campo 2015; Wang et al. 2020, 2023; this study).</p></div>	https://treatment.plazi.org/id/93E2B34570E654AAB636B6E1C55C28DD	Public Domain	No known copyright restrictions apply.

The pileus is pinkish-white to pink and the lamellae are close (55–80 full lamellae per pileus). A key diagnostic feature is the presence of a cortina-like partial veil in young specimens.

The species is distinguished by its off-white basidiomata, often with faint to distinct pinkish tinges, oblong basidiospores measuring 9–10.5 (– 11) × 5–6.8 μm, [Q = (1.44 –) 1.54–2 (– 2.1), Q m = 1.82 ± 0.15], a stipitipellis with abundant gelatinous particles and the absence of clamp connections. It is likely associated with Larix decidua (Candusso 1997; Campo 2015; Wang et al. 2023; this study). The basidiospore dimensions of the Chinese specimen examined in this study align with those reported by Candusso (1997: 9–12.5 × 5–6.8 μm), but differ slightly from the measurements (7.0–10.0 × 4.0–5.5 μm) provided by Wang et al. (2023), possibly reflecting intraspecific variation. Notably, the absence of clamp connections — a feature shared with H. adiaphorus Hesler &amp; A. H. Sm. / H. betulae K. Bendiksen &amp; E. Larss. and H. glutinosus Peck — is rare within the genus Hygrophorus (Hesler and Smith 1963; Candusso 1997; Larsson and Bendiksen 2020; Wang et al. 2023; this study).</p></div>	https://treatment.plazi.org/id/68A7BFE33B4258DFB8E7CF340B9BFA5B	Public Domain	No known copyright restrictions apply.

(2023), exhibits notable morphological and ecological differences. These include a bright coloured (light yellow to orange) pileus, distant lamellae (32–44 full lamellae per pileus), smaller basidiospores (7–8 × 4.5–5 μm, Q = 1.4–1.6) and an autumn fruiting. Together with subtle ITS sequence variation, these features suggest that this specimen may represent a distinct, undescribed species. However, further research and additional collections from the region are necessary to confirm this taxonomic hypothesis.</p></div>	https://treatment.plazi.org/id/B51EA3DB0DA8587185605BA55983A389	Public Domain	No known copyright restrictions apply.
