Numerous fungal morphospecies include cryptic species that routinely are detected by sequencing a few unlinked DNA loci. However, whether the patterns observed by multi-locus sequencing are compatible with genome wide data, such as amplified fragment length polymorphisms (AFLPs), is not well known for fungi. In this study we compared the ability of three DNA loci and AFLP data to discern between cryptic fungal lineages in the three morphospecies Coniophora olivacea, Coniophora arida, and Coniophora puteana. The sequences and the AFLP data were highly congruent in delimiting the morphotaxa Into multiple cryptic species. However, while the DNA sequences indicated introgression or hybridization between some of the cryptic lineages the AFLP data did not. We conclude that as few as three polymorphic DNA loci was sufficient to recognize cryptic lineages within the studied Coniophora taxa. However, based on analyses of a few (three) sequenced loci the hybridization could not easily be distinguished from incomplete lineage sorting. Hence, great caution should be taken when concluding about hybridization based on data from just a few loci. (C) 2012 The British Mycological Society. Published by Elsevier Ltd. All rights reserved.
