中国平伏多孔菌一新种

平伏多孔菌是多孔菌科(Polyporaceae)中的重要类群。其中有许多种类是重要的木材腐朽菌和树木的病原菌。作者1964年曾报道中国扁平多孔菌属(Poria)平伏多孔菌37种。本文报道平伏多孔菌一新种——栎褐孔菌(Fuscoporia quercina Zhao)。

A NEW SPECIES OF RESUPINATE POLYPORES IN CHINA

Resupinate polypores are widely distributed in China. Some of them are the chef causal agents in the decay of living and dead trees as well as of manufactures stocks.The present paper is an additional report of the author's studies on the taxonomy of resupinate polypores in China. In 1964 37 species were reported by the present author from China. In this paper one new species, Fuscoporia quereina Zhao is proposed by the same authorThis is a rare and peculiar species which was only collected from the suburb of Beijing, Sishan and Tan-Zhe-Si in 1950 and 1956. This fungus grew on the trunks of Quercus sp. One of them was an old tree. Its trunk had been wholly rotten from its base to the top and had hollowed in the heartwood when the present author collected this fungi. The other one was a small tree.Sclerotia are present in which there are many conical bodies immersed, which are truncate above, pointed below and are easily separable from the sclerotiumThis species is closely related to Inonotus obliquus (Pers. ex Fr.) Pilat which differs in having setae and larger spores. It is also similar to Inonotus nidus-pici Pilat and Poria andersonii (Ell. & Everh.) Neuman. The former differs in having setae and smaller pores (6鈥? per mm) and the latter differs in having setae and spores of sulphur yellow in mass.All the specimens cited above are deposited in the Mycological Herbarium of Institute of Microbiology, Academia Sinica, Beijing.
