Anamorphic fungi are considered to reproduce asexually. On the one hand they contribute to the dispersal independently from the sexual morph (teleomorph), on the other hand they have the same interaction with the substrate as the sterile mycelium. Because of this important substrate interaction, applied mycology in many cases deals with anamorphs. For understanding the diversity of ecology, evolutionary systematic groups and taxonomy of fungi, the anamorphic stage is most crucial.
