African Morchella crassipes (Ascomycota, Pezizales) revealed by analysis of nrDNA ITS
Degreef, Jérôme Fischer; Sharp, Cathy; Raspé, Olivier
Following the discovery of morel ascocarps with strikingly different morphologies in a single site in Rwanda, we decided to establish the taxonomic identity and origin of afrotropical morels using molecular tools. On the basis of ITS 2 sequences, we showed that all the specimens collected in Rwanda and other specimens from Kenya and Tanzania belong to Morchella crassipes , but form a group differentiated from European and Asiatic accessions. These results along with floristic and biogeographical data from the collection site in Rwanda suggest that M. crassipes is native to the area and has not been introduced recently.
