re-election of the chairman

2007-01-02: Dear colleagues, I am pleased to inform you that the votings for the new chairman and her secretary yielded a clear and positive result. From 14 members, 9 voted and 5 remained silent.  All 9 were "yes" for Irina Druzhinina as chair and Monika Komon-Zelazowska as her secretary. No opposing opinions were heard. I congratulate the two for the clear support, and a glad to put the further fate of Trichoderma, Hypocrea and their taxonomy in the hands. From my side, what is left is to wish you all a happy and prosperous year 2007. Thank you all for your support and collaboration. All the best Christian Univ.Prof. Dr. Christian P.

re-election of ISTH chairperson

2006-12-07: Dear colleagues and friends, dear members of the  International Subcommission on Trichoderma and Hypocrea taxonomy (ISTH), it is now 4 years and a few months that you all have joined the attempt to set up an international network of people interested in taxonomy of Trichoderma, which is nested within the International Commission for the Taxonomy of Fungi (ICTF) and International Union of Microbiological Societies (IUMS, Mycology Division). I am pleased to inform you that ISTH seems to have been very successful in this regards, as we have been mentioned as the best developing Subcommission in the ICTF meeting in Cairns this summer. Also, we have held three ISTH satellite meetings on the occasion of larger conferences at Crimea (2003), Zheijang (2004) and Vienna (2006), which were well attended. Last not least our online strain identification tools have been especially positively mentioned by the US Department of defense, section biohazards. Since ISTH seems now to be established in its field, I think it is time for a change: I have thus decided to retire from my position as  a chair of ISTH. However, as this is an official subcommission with statutes this needs an official  ballot. I am therefore proposing the following:  as you all know, my current "secretary" Irina Druzhinina has been the mastermind of ISTH, and ISTH would not have been that successful and look completely different if she would not have dedicated a lot of her time on the maintenance and development of it. I therefore think she not only is the logical replacement for me, but also (in my opinion) the best available candidate from teh community. I therefore propose her for election as the chair of ISTH. As for the therefrom arising necessity for replacement also of the secretary, I propose Ms. Monika Komon-Zelazowska, a current PhD student of Irina. This would enable her to have permanent contact with the secretary, which makes handling all necessities easier. ...

TrichOKEY 2 final release

2006-08-03: Dear users of ISTH sequence identification tools, we have released TrichOKEY 2 final version. Special features of the second version of the DNA oligonucleotide BarCode for species identification of Hypocrea/Trichoderma: recognizes multiple sequences submitted in FASTA format linked to the Hypocrea/Trichoderma sequence similarity search ( TrichoBLAST) ...

release of alpha TrichOKEY v. 2.0

2006-06-20: Dear TrichOKEY v. 2.0 users, today we have released the penultimate TrichOKEY v. 2.0 which is able to identify multiple sequences submitted in the FASTA format. The program still does not recognize some species from the koningii and viride species complexes. Both of these species groups are now under the detailed investigation by the group of scientists supervised by Gary Samuels. We hope to complete this work in a few weeks and release the barcode which will be able to differentiate the most common species from both clades. ...

TrichOKEY suspended till June 21st

2006-06-16: Dear TrichOKEY users,Due to the current upgrade of the server-side software made by our hosting provider, the current version of the TrichOKEY become inoperative. We are working hard on the code and can assure you that the program is back on 21st of June.Sorry for this inconvenience and thank you for understanding!Best regards,ISTH Team

Lecture of Walter Gams April 7th, 2006 Vienna

2006-06-07: Highlights of progress and remaining problems in the taxonomy of TrichodermaWalter Gams & Tom GräfenhanKEYNOTE LECTURE GIVEN IN THE COURSE OF THE JOINT 4TH ISTH MEETING AND THE 9TH WORKSHOP ON TRICHODERMA AND GLIOCLADIUM, VIENNA, APRIL 2006Trichoderma and Hypocrea comprise such important fungi, that very intense international efforts are justified to study the phylogenetic structure of the genus and species in depth. What could be achieved with morphology alone in differentiating species of Trichoderma, was shown by Bissett, mainly in 1991 (keys to the species also by Gams & Bissett, 1998). Since 1996 molecular approaches are coming into the scene and are modifying the phylogenetic views drastically. But also morphologists have learned much from this work in the subsequent years and refined their cultural techniques and criteria of observation, to be able to distinguish similar taxa that were indicated as distinct in molecular work. In addition, chemical tests have been introduced by Kubicek et al. (2003) and Bissett et al. (2003) using a modified system of Biolog plates to distinguish Trichoderma species. The greatest progress in understanding the phylogenetic structure has been achieved by the combination of DNA-based phylogenetic reconstructions (using several genome fractions) with the thorough morphological study of voluminous material of teleomorphs and anamorphs collected all over the world. 83 species (+ 5 unnamed) of Trichoderma/Hypocrea are now molecularly characterized (Druzhinina & Kubicek 2005, Samuels 2006), in 2000 that were 35. Many of the ca. 400 spp. named in Hypocrea during 200 years are of uncertain identity and some are obviously synonymous (e.g. H. lixii with 2 synonyms), but it is expected that in the whole genus some 400 spp. will have to be distinguished. I have done rather little original work in Trichoderma taxonomy myself but I had the honour of refereeing or editing most of the papers that have come out from this work, including the most recent monographs to be published in Stud. Mycol. 2006. Thus I am in a priviledged more>>

TrichOKEY update

2006-05-06: Dear TrchOKEY users,   due to the current work on the new release of the program it may have some bugs in idertification of species from Trichoderma section Trichoderma, particularly from Rufa Clade and T. koningii species complex.   The alpha version of TrichOKEY2 is being intensively tested by ISTH developers. It is expected to become available in the middle of July.   Best wishes,    Irina Druzhinina ...
