Vahliella isidioidea, found on consolidated soil in the laurel forest from the Canary Islands is described as new to science. A description of the species is given together with notes on its chemistry, distribution, ecology and taxonomy. Possible related lichen taxa are discussed briefly and a key to the Macaronesian species of Vahliella and morphologically related species is also provided.
