根据形态学和ITS分子生物学数据，描述了产于伊比利亚半岛的两个新种-卵状孢水螅的特征是具有深橙子色调的菌毛，对石灰性土壤有强烈的偏好。分布于伊比利亚-地中海地区。Vesterholtii的特点是它的赭石到浅赭石菌盖，几乎所有的收藏都是在比利牛斯山。在最大简约性和贝叶斯ITS聚类分析中，这两个卵孢子种都是单系的，而其余的样品被分配给H。鲁弗斯公司球形担孢子分裂成六个支持良好的分支。本文讨论了对Hydnum rufescens名称进行典型化的必要性，并给出了Hydnum欧洲分类群的临时检索表。
Two new species of Hydnum, characterized by slender Hydnum rufescens-like basidiomes and ovoid to broadly ellipsoid basidiospores, are described from the Iberian Peninsula based on morphological and ITS molecular data. Hydnum ovoideisporum is distinguished by pilei with deep orange tones and strong preference for calcareous soil. It is widespread in the Iberian-Mediterranean area. Hydnum vesterholtii is characterized by its ocher to light ocher pileus, and nearly all the collections were made in the Pyrenees. Both ovoid-spored species are monophyletic well supported groups in the maximum parsimony and Bayesian ITS phylogenies, while the remainder of the samples assigned to H. rufescens s.l. and having globose basidiospores split into six well supported clades. The need to typify the name Hydnum rufescens is discussed, and a provisional key is given for the European taxa of Hydnum.
