The order Entylomatales is a group of fungi within the phylum Basidiomycota, primarily known for being obligate plant pathogens. Members of this order produce smut-like infections on plants, often forming hypertrophied or distorted tissues in their hosts. They are characterized by the production of teliospores, which germinate to produce basidia, following the typical basidiomycete life cycle. Entylomatales species tend to have a narrow host range and exhibit specialized adaptations for infecting specific plant tissues, making them important in the study of plant pathology and fungal evolution. Overall, they represent a small but distinct lineage of biotrophic fungi with unique morphological and ecological traits.
