Accepted Trichoderma names in the year 2015
John Bissett1*, Walter Gams2, Walter Jaklitsch3, and Gary J. Samuels4
Abstract: A list of 256 names of species and two names of varieties in Trichoderma with name or names against which they are to be protected, following the ICN (Melbourne Code, Art. 14.13), is presented for consideration by the General Committee established by the Congress, which then will refer them to the Nomenclature Committee for Fungi (NCF). This list includes 252 species, one variety and one form. Two new names are proposed: T. neocrassum Samuel (syn. Hypocrea crassa P. Chaverri & Samuels), T. patellotropicum Samuels (syn. Hypocrea patella f. tropica Yoshim. Doi). The following new combinations in Trichoderma are proposed: T. brevipes (Mont.) Samuels, T. cerebriforme (Berk.) Samuels, T. latizonatum (Peck) Samuels, and T. poronioideum (A. Möller) Samuels.
The following species are lectotypified: T. americanum (Canham) Jaklitsch & Voglmayr, Gliocladium flavofuscum J.H. Miller, Giddens & A.A. Foster, T. inhamatum Veerkamp & W. Gams, T. konilangbra Samuels, O. Petrini & C.P. Kubicek, T. koningii Oudem., T. pezizoides (Berk. & Broome) Jaklitsch & Voglmayr, T. sulphureum (Schwein.) Jaklitsch & Voglmayr and T. virens (J.H. Miller, Giddens & A.A. Foster) Arx.
Epitypes are proposed for the following species: T. albocorneum (Yoshim. Doi) Jaklitsch & Voglmayr, T. albofulvum (Berk. & Broome) Jaklitsch & Voglmayr, T. atrogelatinosum (Dingley) Jaklitsch & Voglmayr, T. corneum (Pat.) Jaklitsch & Voglmayr, T. cornu-damae(Pat.) Z.X. Zhu & W.Y. Zhuang, T. flaviconidium (P. Chaverri, Druzhinina & Samuels) Jaklitsch & Voglmayr, T. hamatum (Bonord.) Bain., T. hunua (Dingley) Jaklitsch & Voglmayr, T. patella (Cooke & Peck) Jaklitsch & Voglmayr, Hypocrea patella f. tropica Yoshim. Doi, T. polysporum (Link)Rifai, T. poronioideum (A. Möller) Samuels T. semiorbis (Berk.) Jaklitsch & Voglmayr, T. sulphureum (Schwein.) Jaklitsch & Voglmayr, and T. tropicosinense (P.G. Liu) P.G. Liu, Z.X. Zhu & W.Y. Zhuang.
ISTH POLL: YOUR OPINION IS WANTED!
Which generic name you prefer: Trichoderma or Hypocrea?
among several changes a drastic change of the ICBN (International Code of Botanical Nomenclature) was adopted at the IBC in Melbourne in July 2011 for fungi: from 1 January 2013 only one official name will be allowed for each pleomorphic fungus. The ISTH as a subcommission of the International Commission on the Taxonomy of Fungi (ICTF), is expected to decide on the names in Hypocrea and Trichoderma.
The question of which name to use generally follows the principle of priority of publication, BUT
- a new passage in Art. 57.2 says that an anamorph-typified name (e.g. Trichoderma) that has priority must not be taken up until retention of the teleomorph-typified name (e.g. Hypocrea) has been considered by the General Committee and rejected.
- mass conservation: A new Art. 14.n says that lists of preferred names may be submitted to the General Committee, which will refer them to the Nomenclature Committee for Fungi and committees of experts for examination. After approval, these names will then become permanent, i.e. treated as conserved.

This website is designed as an open platform to gather the most recent expert knowledge on Hypocrea/Trichoderma taxonomy and evolution. We also aim to present a collection of easy tools for quick molecular identification of Hypocrea/Trichoderma based on DNA BarCode.
