ISTH POLL 2012: 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.

Welcome to ISTH.info, the official website of the International Subcommission on Trichoderma and Hypocrea Taxonomy!
ISTH is a Subcommission of the International Commission for the Taxonomy of Fungi (ICTF), a Commission of the Mycology Division of the International Union of Microbiological Societies (IUMS Mycology Division).
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.

HOW TO IDENTIFY TRICHODERMA IN A NUT SHELL
Steps suggested for researchers who are studying Hypocrea/Trichoderma biodiversity or performing a global screening for industrially important Trichoderma strains. This step is of crucial importance since several Trichoderma spp. may occupy one ecological niche. Moreover, it is well known that due to homoplasy of morphological characters it is often impossible to discriminate species. 2) Extract genomic DNA from young cultures preferably before sporulation begins We suggest to cultivate Trichoderma strains on agar plates covered by cellophane no longer than 2 - 4 days in order to control possible cross contamination by other Trichoderma cultures. It is also advisable to check DNA quality on agarose gels. If possible, measure DNA concentration 3) make PCR amplification and sequencing of the following marker(s): |

1) Prepare monospore (single spore) cultures for every strain to be identified.
