Dendrochytridium is a fungal genus in the order Chytridiales.
The genus is monotypic, containing the single saprobic species Dendrochytridium crassum, isolated from detritus collected from an Australian tree canopy.
Phylogenetically, Dendrochytridium crassum groups together in a clade with other fungi possessing Group II-type zoospores.
These fungi, which include representatives from the genera Chytridium, Phlyctochytrium, Chytriomyces, and Polyphlyctis are classified in the family Chytridiaceae.
[1] The generic name combines dendro (derived from Greek, meaning "tree"),[2] which refers to the origin of the first collection, and Chytridium, the type genus of the order Chytridiales.
