Hygrophorus penarius sensu lato是一种白色、干燥或仅稍微粘性的相当健壮的蘑菇，与森林山毛榉或栎属形成外生菌群。水青冈和栎的形态之间有轻微的差异。分类法很复杂。这两种形式都被解释为Hygrophorus penarius。基于ITS序列数据，它在这里表明，它们应该被看作是两个不同的物种。由于文献中没有可靠的名称可以用于与栎属相关的种，因此将其描述为一个新种，Hygrophorus penarioides。
Hygrophorus penarius sensu lato is a whitish, dry or only slightly viscid, rather robust mushroom forming ectomycorrhizae with Fagus sylvatica or Quercus spp. There are slight morphological differences between the Fagus and the Quercus forms. The taxonomy has been complicated. Both forms have been interpreted as Hygrophorus penarius. Based on ITS sequence data it is here shown that they ought to be looked upon as two distinct species. As no reliable name in the literature could be used that fits the species associated with Quercus it is here described as a new species, Hygrophorus penarioides.
