Agaricus specimens collected in France belong to two novel entities resembling small forms of A. moelleri and A. xanthodermus, two common species in section Xanthodermatei. Molecular (IT1+ITS2 DNA sequence) and morphological comparisons between eight presumed similar taxa of the section support the elevation of both entities to species rank. The new entities are described as A. parvitigrinus and A. xanthodermulus. They form a group with A. laskibarii, a rare species also recently described from France, and A. californicus, a North-American species. The well known A. moelleri and A. xanthodermus are the most related species among the studied sample. Like other species of the section, both new species have a phenolic odor and are probably toxic.
在法国采集的姬松茸标本属于两个新的实体，类似于小型的摩氏姬松茸和黄皮姬松茸，这是黄皮组中的两个常见物种。该组八个假定相似分类群之间的分子（IT1 + ITS2 DNA序列）和形态比较支持将这两个实体提升到物种等级。新实体被描述为小花纹姬松茸和小黄皮姬松茸。它们与同样最近在法国被描述的稀有物种拉氏姬松茸以及北美物种加州姬松茸组成一个类群。著名的摩氏姬松茸和黄皮姬松茸是研究样本中关系最密切的物种。与该组的其他物种一样，这两个新物种都有酚类气味，可能有毒。
