`*`!Trichoderma asperellum`!`* Samuels, Lieckf & Nirenberg `:cite-ref-1[`F5bf`_`[1`#cite-note-1]`_`f] is a species of `F33f`_`[fungus`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Fungus]`_`f in the family `F33f`_`[Hypocreaceae`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Hypocreaceae]`_`f.`:cite-ref-col-2-0[`F5bf`_`[2`#cite-note-col-2]`_`f] It can be distinguished from `*T. viride`* by molecular and phenotypic characteristics. The most important molecular characteristics are divergent ITS-1 and 28S sequences and RFLP's of the endochitinase gene. Main phenotypic characters are conidial ornamentation and arrangement and branching of the conidiophores.
