摘　　要：本文报道了我国产刺皮属Heterochaete的二个新种,命名为地衣状刺皮Heterochaete lichenoidea Peng et Hu sp.nov。和天目刺皮Heterochaete tianmuensis Peng et Hu sp.nov。前者的子实体极薄,从不超过50μm,形如壳状地衣,刺柱为不规则的乳头状,稀少,子实下层不明显,缺乏胶囊体;后者担子矩圆形或椭圆形,而非纤细的棒状,17-20(22)x9-12μm,孢子肾形,12.5-15(17)x5-7μm。全部研究标本都保藏于湖南师范大学真菌标本室(MHHNU)。Two new species of Heterochaete from China are described in this paper. They are Heterochaete lichenoideda Peng et Hu sp. nov. and Heterochaete tianmuensis Peng et Hu sp. nov. The fructifications of the former are just like the crustaceous lichens, which are very thin, no more than 50μm. Its spines are rare and as irregular papilliforms. Its subhymenium is inconspicuous and no gleocystidia are observed. The basidia of H. tianmuensis are 17-20(22)x9-12μm, oblong or ellipsoidal, neither slender nor clavate. The spores are reniform and vary in 12.5-15(17)x5-7μm in sizes. The similarity among H.tianmuensis, H. brasilliensis, H. crassa and H. sinensis is that all of their fructifications are thick and effused. But the basidia of H. brasilliensis are slender and clavate, and no gleocy stidia are observed. The basldia of H. crassa are oval and much larger than those of the new species (18-27x10-15μm), and the spores are much plumper than those of the new species(14x8μm); The basidia of H. sinensis are obovate or subelavate, and the spores are smaller than those of the new species(9-12x5-6μm). The spores of H. tianmuensis are much similar to those of H. ogasawarsiraensis in the sizes and shapes. But the spines of the latter are blunt, thick and cylindrical, and the basidia are smaller than those of the new species(14-17x10μm). Specimens of the new species are deposited in the Mycological Herbarium of Hunan Normal University (MHHNU)
