本文描述了鹿块菌的两个新种--花绒锦蛇Elaphomericusmarmoratus和鹿块菌E.梭菌属十一月，采集自日本东京的栎属次生林。这两个种与E. muricatus和E. granulatus;前者的囊柄不带紫色，后者的网状子囊孢子更接近E.粗糙。分子系统发育分析也支持这些标本作为新物种的分配。与已知种的ITS rDNA同源性较低（< 91%和< 97%）。此外，系统发育树使用相邻连接和最大似然法表明，这两个新物种的序列中的每一个形成一个单系组内部分Elaphomelae与引导支持率为99%。外生菌根根与子囊菌同时收集的分析表明，E。marmoratus至少与赤松（Pinus densiflora）共生，而E. fuscus至少与Q. serrata.© 2020日本真菌学会。出版社：Elsevier BV版权所有。
We describe two new species of deer truffle, Elaphomyces marmoratus and E. fuscus spp. nov., collected from a secondary forest dominated by Quercus serrata, in Tokyo, Japan. Both species have morphological similarities to E. muricatus and E. granulatus; however, the former has a gleba without a purplish color and the latter has reticulated ascospores more closely resembling E. asperulus. Molecular phylogenetic analyses also support the assignment of these specimens as new species. ITS rDNA homologies with known species were low (< 91% and< 97%). In addition, phylogenetic trees using neighbor-joining and maximum likelihood methods showed that the sequences of the two new species each formed a monophyletic group within section Elaphomyces with bootstrap support of 99%. Analyses of ectomycorrhizal roots collected concurrently with the ascomata revealed that E. marmoratus is associated with at least Pinus densiflora, while E. fuscus is associated with at least Q. serrata.© 2020 The Mycological Society of Japan.
