Description:
Diagnosis: Pileus plano-convex, brownish yellow, dry, subtomentose, 6.2.7.9 cm broad, with NH4 vinaceous red. Spores subfusoid or ellipsoid. Context pale yellow, staining pale blue. Lamellae decurrent, bright yellow, intervenose, staining blue (then brown). Stipe tapering downwards, pale yellow to light ochraceous. Context whitish yellow. Basal mycelium yellow. Spores 8.4–9.8 × 3.5.4.2 µm. Clamp connections absent.
Registration number: MB 563622
Type: THAILAND. Chiang Mai Province: Ban Pha Deng village, Pathummikaram temple, 19°06'28.8''N, 98°44'47.3''E, 1050 m, 12 June 2006, Neves 128 (HOLOTYPE: MFLU08 1109, ISOTYPE: NY).
Distribution: Northern Thailand
Ectomycorrhiza: Castanopsis
Commentary: The two different spore morphologies are evident in the collections and a very diagnostic character for this taxon.The different shape of the caulocystidia at the base versus the apex of the stipe, and the vinaceous red reaction with NH4 on the pileus are also diagnostic. Phylloporus bellus is a close species, reported from the neotropics by Singer and described by Massee from the Paleotropics, that produces spores in two size classes in some collections, but the caulocystidia are morphologically consistent. The vinaceous red reaction to NH4 does not occur in P. bellus.
