Pythium ornacarpum sp. nov. was isolated from a soil sample taken from Genlis in the Burgundy region of France. This species is unique because of its ornamented oogonia which are completely surrounded by antheridial filaments. The fungus is closely related to Pythium echinulatum Matthews. Morphological and reproductive aspects of this species as well as a study by PCR of the sequence of the internal transcribed spacer (ITS1) of the nuclear ribosomal gene and its comparison with related species are described here. The nucleotide sequence of the ITS1 region flaking the 5.8S rRNA of this species and other related species are also given here.
新种饰果腐霉从法国勃艮第地区热利市采集的一份土壤样本中分离得到。该物种独特之处在于其具饰纹的藏卵器，藏卵器完全被雄器丝环绕。该真菌与刺状腐霉密切相关。本文描述了该物种的形态学和繁殖特征，以及通过聚合酶链式反应（PCR）对核糖体基因内部转录间隔区（ITS1）序列进行的研究及其与相关物种的比较。同时还给出了该物种及其他相关物种的5.8S rRNA两侧ITS1区域的核苷酸序列。
