Practice question

Deuteromycetes traditionally designated Fungi Imperfecti represent artificial form-group where sexual teleomorphic phase remains undiscovered despite extensive culture attempts, so classification relies on asexual anamorph characteristics solely. Lack of ascocarps, basidiocarps or zygosporangia means primary taxonomic criteria of sexual reproduction cannot apply. Mycelium usually septate with dolipore or simple septa, reproduction via conidia or sterile mycelia only. Molecular phylogenetics using ITS, LSU rDNA now nests most deuteromycetes within Ascomycota and Basidiomycota indicating secondary loss of sexuality, yet practical identification continues using absence of observed sexual reproduction as diagnostic imperfect designation.
