Kiliasia is a genus of lichen-forming fungi in the family Ramalinaceae.[1] It comprises seven species.[2]
It was originally erected by Josef Hafellner in 1984 as a monospecific genus to accommodate the species Kiliasia athallina.[3] The genus was later included in Toninia by Einar Timdal in 1992.[4] However, molecular phylogenetics studies by Sonja Kistenich and colleagues (2018) have shown that Kiliasia represents a distinct lineage within the Ramalinaceae, leading to its resurrection as a separate genus. Several species now placed in Kiliasia were originally described in other genera such as Biatora, Catillaria, and Lecidea before being transferred to Toninia and then Kiliasia.[5]
Kiliasia corresponds partly to Timdal's (1992) Toninia groups 1, 3, and 7. It forms a distinct clade within the Toninia-group of the Ramalinaceae in molecular phylogenies.[5]
