Novel chytrid lineages dominate fungal sequences in diverse marine and freshwater habitats
In aquatic environments, fungal communities remain little studied despite their taxonomic and functional diversity. To extend the ecological coverage of this group, we conducted an in-depth analysis of fungal sequences within our collection of 3.6 million V4 18S rRNA pyrosequences originating from 3...

In aquatic environments, fungal communities remain little studied despite their taxonomic and functional diversity.
