- <p><i>Tricholosporum porphyrophyllum</i> (S. Imai) Guzmán ex T.J. Baroni, Mycologia 74(6): 868 (1982) (FIGURES 1–6)</p><p>≡ <i>Tricholoma porphyrophyllum</i> S. Imai, J. Coll. agric., Hokkaido Imp. Univ. 43: 69 (1938)</p><p>≡ <i>Tricholosporum porphyrophyllum</i> (S. Imai) Guzmán, Bol. Soc. Mex. Micol. 9: 63 (1975)</p><p>Description:— <i>Pileus</i> 3.5–6 cm, hemispheric, convex to plane, border enrolled slightly when immature, with brown to lilac hues, surface smooth and slightly sticky when wet. <i>Context</i> white, 3–5 mm thick in central. <i>Lamellae</i> adnate or sinuate, crowded, lengths unequal with lamellulae, 3–4 mm broad, violet, slightly changing to brown when bruised. <i>Stipe</i> 3–7 cm long, 0.6–1.0 cm thick at apex, solid, fibrous, violet to grayish violaceous at first, then gradually changing to yellowish to white when mature, cylindrical or slightly expanded downward, white basal mycelium.</p><p><i>Basidiospores</i> starlike or cruciate, 6.25–7×5–5.5 μm, colorless, inamyloid. <i>Basidia</i> clavate, 27.5–30×6.25–7.5 μm, colorless. <i>Pleurocystidia</i> and <i>cheilocystidia</i> absent. <i>Hymenophoral trama</i> parallel, with oleiferous hyphae, 2.8–4.6 μm in diam., with clamp-connections on hyphae of hymenium, and also on hyphae of pileus and stipe.</p><p>Specimens examined:— CHINA. Liaoning Province, Fu Shun City, HunHeyuan Nature Reserve of Liaoning Province, N41°52´, E124°50´, 510 m above sea level, 22 August 2011 and 31 July 2012, <i>HMJAU 24949</i>.</p><p>Habitat:—mixed coniferous broad-leaved forest.</p><p>Known distribution:— Japan (Hongo, 2001), China.</p><p>Comments:— <i>Tricholosporum porphyrophyllum</i> is similar to <i>Tricholosporum subporphyrophyllum</i> in some characteristics, such as the colour of pileus, lamellae and stipe, but slightly different in size. <i>T. subporphyrophyllum</i> is smaller with pileus (2–5.7 cm) and stipe (3–5 cm), and it also has hymenial cystidia that are absent in <i>T. porphyrophyllum</i> (Guzmán, 1975). Construction of the phylogenetic tree based on ITS, nlsu, rpb2 sequences showed that the two samples collected in the same nature reserve have high bootstrap support value. The species of <i>T. porphyrophyllum</i> has different taxonomic status in these phylogenetic trees constructed in a different sequence, but there is a higher support that shows it belongs to Tricholomataceae.</p>
