Solioccasus polychromus gen. & sp. nov., the most brightly colored hypogeous fungus known, is described from Papua New Guinea and tropical northern Australia south into subtropical forests along the Queensland coast and coastal mountains to near Brisbane. Phylogenetic analysis of molecular data places it as a sister genus to Bothia in the Boletineae, a clade of predominantly ectomycorrhizal boletes. Ectomycorrhizal trees, such as members of the Myrtaceae (Eucalyptus, Corymbia, Lophostemon, Melaleuca spp.) and Allocasuarina littoralis, were present usually in mixture or in some cases dominant, so we infer some or all of them to be among the ectomycorrhizal hosts of S. polychromus.
双色地星菌，已知颜色最鲜艳的地下真菌，产自巴布亚新几内亚和澳大利亚北部热带地区，向南延伸到昆士兰海岸和沿海山脉的亚热带森林，直至布里斯班附近。分子数据分析的系统发育分析将其置于Boletineae 中的 Bothia 为姐妹属，Boletineae 是一个主要外生菌根菌的牛肝菌科真菌类群。外生菌根树，如桃金娘科（桉树、南洋杉、千层树、白千层属等）和滨海木麻黄，通常以混合物或在某些情况下占主导地位存在，因此我们推断它们中的一些或全部可能是双色地星菌的外生菌根宿主。
