Species of the genus are collected in association with a subterranean mass generally referred to as a sclerotium. This is one of the few genera of the not associated with plant material - wood or leaves. The sclerotium is composed of hyphae of both species and species. To verify the existence of species in the sclerotia of those species not previously examined and to fully understand the structure and nature of the sclerotium, molecular data and morphological characters were analyzed. Using nuclear ITS rDNA sequences the species co-occurring with species were identified from all examined material. These symbionts fall into two main groups - the group and the group. Divergent time estimates of the and lineages support a co-evolutionary relationship between these two fungi.
该属的物种是与一种通常被称为菌核的地下团块一起采集的。这是少数几个不与植物材料（木材或树叶）相关的属之一。菌核由该属物种和其他物种的菌丝组成。为了验证在以前未检查过的那些物种的菌核中该属物种的存在，并充分了解菌核的结构和性质，对分子数据和形态特征进行了分析。利用核ITS rDNA序列从所有检查的材料中鉴定出与该属物种共生的其他物种。这些共生体分为两个主要的类群——该类群和另一类群。对这两个类群谱系的分歧时间估计支持了这两种真菌之间的共同进化关系。
