本文记述了采自江西省的一新种--褐头假Hydynumbrunneiceps。形态学特征为：担子果凝胶状，菌毛淡黄棕色，暗红棕色至微黑绒毛状，刺圆锥状，白色，担孢子球形至宽椭圆形。28 S区和ITS区序列的系统发育分析也证实了棕头披碱草在拟棘藓属中形成了一个独立的谱系。提供了描述、新鲜担子瘤的照片和显微结构的线条图。此外，还应采用更具代表性的样品，对我国已有的明胶假单胞菌的分子生物学记录进行重新评价。
Pseudohydnum brunneiceps is described as a new species from Jiangxi Province, central China. Morphologically, it is characterized by a gelatinous basidiocarps, pilei pale yellowish brown, dark reddish brown to blackish velutinate, spines conical and white, and basidiospores globose to broadly ellipsoidal. Phylogenetic analyses of DNA sequences from partial 28S region and internal transcribed spacer (ITS) also confirm that P. brunneiceps forms an independent lineage within Pseudohydnum. A description, photographs of the fresh basidiomata and line-drawings of the microstructures are provided. In addition, the previous records of P. gelatinosum in China should be re-evaluated by more representative samples by molecular phylogeny.
