During a taxonomic revision on cantharelloid fungi in China, Cantharellus cibarius var.
squamosus A. Pöll apud J. Murr, a new Chinese record was confirmed base on four collections. The
paper provides full description and illustration of the variety, and relative information about the
variety is introduced. The specimens cited in the paper were preserved in Herbarium Mycologicum
Academiae Sinicae (HMAS) and Herbarium of Institute of Microbiology, Guangdong (HIMGD).
Cantharellus cibarius var. squamosus A. Pöll apud J. Murr, Öesterr. Bot. Zeitschr. 66: 91 (1916).
Figs. 1, 2
Basidiomata up to 10cm high, on the ground, solitary to gregarious. Pileus 2.5-6cm diam.,
convex to turbinate when young, then applanate with depressed center, infundibuliform or irregular
when mature, margin incurved when young, lobed when mature; surface egg-yellow to orange, center
sometimes yellowish-brown, with brown to dark brown fibrillose squamules, margin slightly paler,
dry. Hymenial surface deeply decurrent, pseudolamellate, with anastomosing ridges, dichotomous,
interveined, yellowish, pinkish-yellow to orange. Stipe 3-6 × 0.6-1.5cm, cylindrical or slightly
tapering downward; surface yellow to orange, yellowish-ochre, with small brown fibrillose
squamules; solid. Context up to 6mm thick in center of pileus; orange in pileus, pale yellow to yellow
in stipe; fleshy. Odor fragrant. Taste unknown. Basidiospore deposit pale yellow to pinkish-yellow.

Basidiospores (8-) 8.5-10 (-10.5) × (5-) 5.5-6.5μm, average 9.3 ± 0.6 × 6.0 ± 0.3μm, Q = 1.3-1.9,
average 1.55 ± 0.2, n = 54, mostly ellipsoid, rarely ovoid, smooth, thin-walled, subhyaline or
yellowish for colored multiguttulate contents. Basidia 62-95 × 7-10.5μm, subcylindrical to
elongate-clavate, bearing 2-8 sterigmata, mostly 4-6, with basal clamp connexions, multiguttulate,
thin-walled, hyaline, subhyaline or with few opaque contents. Cystidia unfound. Hymenium
thickening. Subhymenial layer of narrow hyphae, 2-5 (-7)μm diam., yellowish, thin-walled, with pale
yellow contents and numerous clamp connexions. Hyphae of pileus surface 2.5-5 (-7)μm diam.,
radially parallel, yellowish, thin-walled, with numerous clamp connexions. Hyphae of pileus context
2.5-5μm diam., rarely inflated up to 11μm, yellowish, thin-walled, with pale yellow contents and
numerous clamp connexions. Hyphae of stipe margin 1.5-6μm diam., cylindrical, longitudinally
parallel, pale yellow, thin-walled, with pale yellow contents and numerous clamp connexions.
Hyphae of stipe context 2.5-12μm diam., cylindrical, longitudinally parallel, yellowish, thin-walled,
with yellowish content and numerous clamp connexions.

Remarks: Cantharellus cibarius Fr. is the most common species with many varieties and forma
for its wide morphological variation (Corner 1966; Pegler et al. 1997). Cantharellus cibarius var.
squamosus was proposed by Pöll in Murr (1916), the variety is distinguished from most other
intraspecific taxa by its squamulate pileus and stipe (Murr 1916; Corner 1966), and it differs from
another squamulate variety, C. cibarius var. squamulosus (A. Blytt) Eyssart. & Buyck (Corner 1966;
Eyssartier & Buyck 2000), by its egg-yellow pileus, whereas the latter has rufous-brown pileus. The
Chinese collections completely coincide with description of C. cibarius var. squamusus (see Murr
1916; Corner 1966), and therefore the correctness of our identification seems certain. The variety was
previously only reported from Austria (Murr 1916; Corner 1966). The discovery of the fungus in
China further expands its distribution in the northern hemisphere.
