摘要

块茎是核桃科外生菌根真菌属，具有重要的寄主伴生物种多样性。根据两种核糖体标记(ITS和LSU)的生态学、形态学和系统发育特征，提出了石竹属(Tuber caryophilum)作为新种。该物种的特征是在墨西哥科阿韦拉和奇瓦瓦州Comarca Lagunera的山核桃(Carya illinensis, nogal pecanero)的根上形成外生菌根，并具有18-48 × 10-27 μm的针孔子囊孢子。caryophilum属于Rufum分支，是Tuber thelascum的姐妹种，后者是墨西哥北部报道的与canbyi栎和Q. polymorpha有关联的一种。这两种松露属于美国南部和墨西哥北部的一个分支，与栎属和山核桃属的分类群有关，如lyonii块菌。

Tuber caryophilum, a new truffle species growing in Carya illinoinensis orchards

Tuber is a genus of ectomycorrhizal fungi with an important diversity of species associated with hosts in Juglandaceae. Tuber caryophilum is proposed as a new species based on ecological, morphological and phylogenetic characters of 2 ribosomal markers (ITS and LSU). This species is characterized by forming ectomycorrhizae on the roots of Carya illinoinensis (nogal pecanero) in the Comarca Lagunera of Coahuila and Chihuahua, Mexico and by exhibiting 18-48 × 10-27 μm echinulate ascospores. Tuber caryophilum belongs to the Rufum clade and is the sister species of Tuber theleascum, a species reported in northern Mexico associated with Quercus canbyi and Q. polymorpha. These 2 truffles belong to a clade from the southern USA and northern Mexico with taxa associated to Quercus and Carya, such as Tuber lyonii.
