This contribution provides a synopsis of the presentations and discussions during the SIG session on cryptic speciation in lichen-forming fungi held during IMC9. In several cases, a re-examination of morphology against the background of molecular phylogenetic evidence revealed, sometimes subtle, morphological and/or chemical characters, supporting the distinction of particular clades at species level. However, there are also examples of cryptic species in which no morphological characters could be identified to distinguish between lineages. Several cases were presented in which distinct lineages are correlated with biogeographical patterns. When and how to name cryptic species was debated, and the use of terms such as "complex" or "aggregate" commended where the taxa formed part of a single lineage.

  • Scope: All aspects of pure and applied mycological research and news.
    Aims: The flagship journal of the International Mycological Association. IMA Fungus is an international, peer-reviewed, open-access, full colour, fast-track journal. Papers on any aspect of mycology are considered, and published on-line with final pagination after proofs have been corrected; they are then effectively published under the International Code of Nomenclature for algae, fungi, and plants. The journal strongly supports good practice policies, and requires voucher specimens or cultures to be deposited in a public collection with an online database, DNA sequences in GenBank, alignments in TreeBASE, and validating information on new scientific names, including typifications, to be lodged in MycoBank. News, meeting reports, personalia, research news, correspondence, book news, and information on forthcoming international meetings are included in each issue.
