A new monotypic sequestrate genus, is described based on collections from the Neotropical forest of Atlantic forest in Paraíba, Northeast Brazil - an area known for its high degree of endemism. The striking features of this new fungus are the hypogeous habit, the vivid yellow peridium in mature basidiomes, broadly ellipsoid basidiospores with a distinct wall that is ornamented with longitudinal striations and lageniform cystidia with rounded apices. Phylogenetic analysis, based on LSU and regions, showed that the type species, , is phylogenetically sister to the monotypic sequestrate African genus in Boletaceae. Together these two species formed the earliest diverging lineage in the subfamily Zangioideae. is found in nutrient-poor white sand habitats where plants in the genera (Polygonaceae) and (Nyctaginaceae) are the only potential ectomycorrhizal host symbionts.
基于从巴西东北部帕拉伊巴大西洋森林的新热带森林采集的样本，描述了一个新的单型地下真菌属——该地区以其高度的特有性而闻名。这种新真菌的显著特征是地下习性、成熟担子果中鲜黄色的包被、具明显壁且有纵向条纹装饰的宽椭圆形担孢子以及顶端圆形的瓶形囊状体。基于 LSU 和 区域的系统发育分析表明，模式种 与牛肝菌科单型地下非洲属 在系统发育上是姐妹关系。这两个物种共同构成了赞氏亚科中最早分化的谱系。 在营养贫瘠的白沙栖息地被发现，其中蓼科的 和紫茉莉科的 属植物是唯一潜在的外生菌根宿主共生体。
