Zhao, 2024090818 (HKAS 147005) ; ibid., 8 September 2024, G. Zhao, 2024090823 (HKAS 147007) .</p><p>Notes.</p><p>In the multi-locus phylogenetic analysis, L. daliensis is closely related to L. salmonicolor A. W. Wilson &amp; G. M. Muell. However, L. salmonicolor is distinguished by its reddish-brown basidiomata that fade to pale buff, salmon-pink lamellae, and globose spores with medium-sized spines (2–5 × 1–2 μm vs. 1–3 × 1–2 μm) (Wilson et al. 2013).</p><p>Macroscopically, Laccaria daliensis exhibits similarities to several allied species — including L. stellata Popa &amp; S. Y. Castillo, L. himalayensis A. W. Wilson &amp; G. M. Muell., L. aurantia Popa, Rexer, Donges, Zhu L. Yang &amp; G. Kost, L. indohimalayana K. Das, I. Bera &amp; Vizzini, L. umbilicata Ming Zhang, L. nitrophila Corrales, Ovrebo, A. W. Wilson &amp; G. M. Muell., L. araneosa H. J. Cho &amp; Y. W. Lim, and L. albifolia Dovana &amp; Para — particularly in its orange pileus coloration. Its overall appearance is especially similar to that of L. stellata and L. umbilicata, making them difficult to distinguish solely on macromorphology. Reliable differentiation, therefore, relies on micromorphological characteristics. Compared to L. umbilicata, L. daliensis has smaller basidiospores (minimum width &lt;8 μm) and distinctly smaller cheilocystidia (18–30 × 3–7 μm) and pleurocystidia (13–22 × 3–6 μm), whereas L. umbilicata possesses larger cheilocystidia (30–47 × 3–8 μm) and pileocystidia (28–38 × 4–6 μm) and lacks pleurocystidia (Zhang et al. 2023). When contrasted with L. stellata, L. daliensis shows a broader basidiospore width range (up to 9.8 μm) and distinctly produces both cheilocystidia and pleurocystidia, structures not reported in the original description of L. stellata (Popa et al. 2016) . L. daliensis differs from L. himalayensis by having more prominent spore ornamentation, with longer and wider spines (2–5 μm long, 1–2 μm wide at the base vs. (0.5 –) 1–3 μm long and &lt;1 μm wide in L. himalayensis), along with abundant cheilocystidia and pleurocystidia, which are absent in L. himalayensis (Wilson et al. 2013) . Compared to L. aurantia, L. daliensis has distinctly smaller basidiomata, and its basidiospores, basidia, and cystidia are all consistently smaller (Popa et al. 2014). Laccaria daliensis can be distinguished from L. indohimalayana by its smaller basidiomata, broader basidiospores, and the presence of both cheilocystidia and pleurocystidia, structures that are entirely absent in the latter species (Wang et al. 2019).</p><p>Micromorphologically, Laccaria daliensis can be distinguished from L. nitrophila by its smaller basidiospores (av. 7.8 μm), longer and wider spore spines, and the presence of distinct cheilocystidia and pleurocystidia — structures completely absent in the latter (Corrales et al. 2020). Compared to L. araneosa, L. daliensis possesses a differentiated subhymenium, both cheilocystidia and pleurocystidia (lacking in L. araneosa), and longer, thicker spore spines (Cho et al. 2018). When contrasted with L. albifolia, the former features longer and thicker spines (2–5 μm long, 1–2 μm wide at the base), subglobose to globose basidiospores (av. 7.8 × 7.7 μm), the presence of distinct pleurocystidia, and a pileipellis composed of appressed, parallel hyphae. In contrast, L. albifolia is characterized by very short spines (up to 1.2 μm long, &lt;1 μm wide at the base) and more variable basidiospore shapes (globose to ellipsoid, with a maximum Q value of 1.40) (Dovana et al. 2025).</p></div>	https://treatment.plazi.org/id/ADD02B6B8A2F55BDBB436B011C3235D8	Public Domain	No known copyright restrictions apply.

Stipitipellis composed of appressed, parallel, simply septate, thick-walled, hyphae 4–8 µm wide; stipe trama is composed of longitudinally arranged, grayish in 5 % KOH, clavate terminal cells, infrequently branching, septate, thick-walled, hyphae hyaline 3–10 µm wide.

However, L. fulvogrisea can be distinguished by its gray to brownish pileus and lamellae, larger stipe (30–70 × 3–5 mm) that is slightly darker gray than the pileus, larger basidia (40–50 × 10–15 µm), clavate and flexuous pleurocystidia, cheilocystidia (30–50 × 3–7 µm) ranging from clavate to subcapitate, and the absence of caulocystidia on the stipe surface (Popa et al. 2014). The ITS sequence divergence between L. violaceonana (HKAS 123243) and L. fulvogrisea (KUN F 78556) is 2.03 % (12 / 591, excluding gaps).</p><p>Macroscopically, Laccaria violaceonana shares purple basidiomata with L. amethystina, L. amethysteo-occidentalis G. M. Muell, L. dallingii Corrales, Ovrebo, A. W. Wilson &amp; G. M. Muell, L. japonica Popa &amp; K. Nara, L. moshuijun, and L. violaceotincta K. P. D. Latha, K. N. A. Raj &amp; Manim but can be distinguished by a combination of micromorphological characteristics. Compared with L. amethystina and L. amethysteo-occidentalis, L. violaceonana possesses abundant pleurocystidia, which are absent in the latter two species. Additionally, its basidiospores (6.0–9.6 × 5.4–9.0 µm) are smaller than those of L. amethystina (7.5–9.5 × 7.5–9.5 µm), its basidia (29–47 × 10–16 µm) are smaller than those of L. amethysteo-occidentalis (34–56.5 × 9.7–14.7 µm), and its narrowly utriform cheilocystidia (26–76 × 4–13 µm) differ in shape from those of both species (Cooke 1884; Mueller 1984). In contrast to L. dallingii, L. violaceonana has pleurocystidia and narrowly utriform rather than simple cylindrical cheilocystidia and lacks the distinctive orange-pink KOH reaction of the hyphae observed in the latter (Corrales et al. 2020). It is distinguished from L. japonica and L. moshuijun primarily by its hyphal structure: L. violaceonana has appressed, parallel hyphae in both the pileipellis and stipitipellis, in contrast to the interwoven, radiating hyphae with intracellular pigmentation found in the latter two species. Furthermore, the spore spines of L. violaceonana (1–4 µm long) are longer than those of L. japonica (0.8–1 µm), and its cheilocystidia are narrowly utriform, differing from the cylindrical to clavate or apically branched or capitate forms found in L. japonica and L. moshuijun (Popa et al. 2017 a, 2017 b). The most notable distinction from L. violaceotincta is the presence of pleurocystidia in L. violaceonana, along with a broader spore size range (6.0–9.6 × 5.4–9.0 µm vs. 7–8 × 7–8 µm) (Latha et al. 2019).</p></div>	https://treatment.plazi.org/id/3CF12F84F73759629E787AADEDA7E13F	Public Domain	No known copyright restrictions apply.
