Accepted Trichoderma names in the year 2015.

Area of Science:

• Mycology
• Plant Pathology
• Taxonomy

Background:

• The fungal genus Trichoderma is crucial in agriculture and biotechnology.
• Accurate species identification and nomenclature are vital for effective application and research.
• Previous taxonomic work has led to ambiguities in Trichoderma classification.

Purpose of the Study:

• To propose a list of 254 species and two varieties of Trichoderma for protection under the International Code of Nomenclature for algae, fungi, and plants (ICN).
• To introduce new names and combinations to resolve taxonomic uncertainties.
• To provide lectotypifications and epitypifications for key Trichoderma species.

Main Methods:

• Compilation of species names for nomenclature protection following ICN Article 14.13.
• Proposal of two new names: T. neocrassum and T. patellotropicum.
• Formation of new combinations for existing species within the Trichoderma genus.
• Selection of lectotypes and epitypes for numerous Trichoderma species to stabilize their classification.

Main Results:

• A list of 254 species and two varieties in Trichoderma has been prepared for official consideration.
• Two new species names, T. neocrassum and T. patellotropicum, are proposed.
• Four new combinations are presented, including T. brevipes and T. cerebriforme.
• Lectotypes and epitypes were designated for 23 species, clarifying their taxonomic status.

Conclusions:

• The proposed nomenclatural actions will enhance the stability and clarity of Trichoderma taxonomy.
• This work supports the accurate identification and utilization of Trichoderma in scientific and applied fields.
• The list and taxonomic revisions are submitted for review by the relevant international committees.
