GlobalFungi is a collection and validation of data published on the composition of fungal communities in terrestrial environments including soil and plant-associated habitats. Users can search for individual sequences, fungal species hypotheses, species or genera, to get a visual representation of their distribution in the environment and to access and download sequence data and metadata. In addition, the user interface also allows authors to submit data from studies not yet covered and in this way to help to build the resource for the community of researchers in systematics, biogeography, and ecology of fungi.
