ABSTRACT: A new species, Xerocomus tengii, belonging to the family Boletaceae is described
and illustrated.
KEY WORDS: Xerocomus tingii sp.nov., Boletaceae

The genus Xerocomus of China was investigated intensively over the past 70 years ( Teng,
1939, 1996; Chiu, 1948, 1957; Ying,1986; Zang, 1996, Zang & Huang, 2002 ). A taxon having
small size basidiocarps collected from Fujian is found to be a new and named Xerocomus tengii.
The taxon belongs to the Family Boletaceae. It is described and illustrated.

Pileus 4 ~ 6 mm broad, convex when young, expanding to plain, surface dry. tomentose, ochre –
yellow or yellowish brown. Context 0.8~1.1 mm thick, yellowish, unchanging on exposure.
Hymenophore yellow , tubes 0.4~0.6 mm long, yellowish, sublamellate, often quite lamellate near
the stipe, somewhat sunken at the center. Pores 3~4 per mm, rounded to angled. Stipe 0.9~1.1 ×
0.1~0.15 cm, clavate to equel, yellowish brown, not reticulate but striate, base whitish.
Basidiospores 15~16.5 × 5~5.5 ìm, ellipsoid, smooth, hyaline to pale yellow microscopically.
Basidia obclavate 19~26 × 7.8~10 ìm. Pleurocystidia 26~36 × 7~10 ìm, broadly fusiform.

Cheilocystidia 40~45 × 6~8 ìm, fusiform. Tube trama parallel and divaricate, central striae
longitudinal parallel distinct.
Etymology: Latin: tengii = in honor of mycologist Prof. S. C. Teng
Commentary: The small size basidiocarps seem similar to Boletus minimus M. Zang et N.
L.Huang (2002) but the fungus is distinguished by tomentose pileus . The tubes of hymenium are
always quite lamellate and around the stipe. T he basidiospores are longer and broader, 15~16.5
× 5~6.2 ìm.

Institute of Botany, Academia Sinica ) for correcting the Latin diagnosis and financed by a

*欣逢邓公叔群百年诞辰，他对我国菌物学和林学研究的开拓，劳瘁终生，万里云程。望松楸目断，仰
慕延伫。近在福建省三明市附近的瑞云山发现一菌盖径仅 4~6 mm 的微型绒盖牛肝菌 ,其担孢子和囊状
体等的构造均不同于已知种 , 敬以此新种取名叔群绒盖牛肝菌 Xerocomus tengii Zang, Lin et Huang. 篆
感纪念。
