Cantharellus zangii is a species of fungus in the family Cantharellaceae. Described as new to science in 2012, it is found only in a small area in northwestern Yunnan, China. The fungus produces small, ochre to ochre-yellow fruit bodies (mushrooms) with thin flesh and a long tapering stipe. Microscopically, the mushroom features thin-walled hyphae with clamp connections, and large ellipsoid-shaped spores.
Cantharellus zangii was described in 2012 in the scientific journal Mycotaxon by Xiao-Fei Tian and colleagues. The type collection was made in August 2008 in the Bitahai National Natural Reserve, located in Shangri-La County, Yunnan, China.[1] The authors classify the fungus in Parvocantharellus, a subgenus of Craterellus that was originally proposed by Guillaume Eyssartier and Bart Buyck in 2001.[2] The specific epithet zangii honors Chinese mycologist Zang Mu, founder of the Cryptogamic Herbarium in the Kunming Institute of Botany.[1]
Description
Fruit bodies have caps ranging in shape from umbonate to flat to slightly concave, reaching a diameter of 2–3 cm (3⁄4–1+1⁄4 in). The cap is smooth with an ochre to yellow colour. Initially curved inward, the cap margin eventually straightens in maturity. The golden-colored gills, which have a decurrent attachment to the stipe, are up to 2 mm high with a 1–2 mm spacing between them. They are connected by transverse cross-veins. There are short, branched gills near the cap edge. The dark orange-yellow to orange stipe measures 7–8 cm (2+3⁄4–3+1⁄4 in) long by 0.3–0.4 cm thick. It is hollow and sometimes slightly curved. The thin flesh has a mild taste and an odor similar to Osmanthus flowers.[1]
Spores are ellipsoid, thin-walled, and hyaline (translucent), measuring 8.5–11 by 5–6.5 μm. They sometimes have multiple tiny oil droplets. Basidia (spore-bearing cells) are slender and club-shaped, usually five-spored (sometimes six) with sterigmata 5–6 μm long, and dimensions of 75–85 by 6–9 μm. All hyphae have distinct clamp connections.[1]
Similar species
Similar species include the European Cantharellus queletii, but this mushroom can be distinguished by its solid stipe and the lack of cross-veins between the gills. Another European species, Craterellus tubaeformis, has a horn-shaped fruit body with depressed caps, and grey or greyish-white gills.[1]
