| Abstract: | Unexpected contaminants uncovered during routine COI‐5P DNA barcoding of British Columbia Kallymeniaceae indicated the presence of a novel lineage allied to the family Meiodiscaceae, Palmariales. Available rbcL data for species of this family were used to design specific primers to screen for the presence of the meiodiscacean species in 534 kallymeniacean specimens primarily from British Columbia, Canada. Ultimately, 43 positive PCR products representing six diverse genetic groups from nine host species were uncovered; three are described here in the new genus Kallymenicola gen. nov., viz., K. invisiblis sp. nov., K penetrans sp. nov., and K superficialis sp. nov. Although genetic groups loosely displayed evidence of host specificity and cospeciation, examples of host switching with interesting biogeographical patterns were also documented. |
