T/H Vote results:


Below are the comments left by members of ISTH who took part in Trichoderma/Hypocrea vote


Kolli Sarojini voted for Trichoderma:

I prefer to name the genus as Trichoderma as it is very easy to identify and describe it in its anamorphic form


Elizabeth Medina Castellanos voted for Trichoderma:

higher degree in morphological variation in some groups of the genus.
a much higher number of citations in applied microbiology and biotechnology due to the wide use in economic applications and considerations


Gaston Ezequiel voted for Trichoderma:

It is widely used in numerous scientific publications


Benjamin Horwitz voted for Trichoderma:

used in a huge literature; according to Art. 57 the research community has the choice, once both names for the genus have been considered


Babak Pakdaman Sardrood voted for Trichoderma:

Trichoderma, the anamorphic form is more familiar and the most commonly encountered form in nature. While I have seen the green mold for several times, I have never observed Hypocrea form.


Abdul Hannan voted for Trichoderma:

Trichoderma is more famous and well known than Hypocrea


mojegan kowsari voted for Trichoderma:

Trichoderma is more wide use and easier for economic application.


Chelkowski Jerzy voted for Trichoderma:

Trichoderma is commonly used and only few scientists working on Ascomycota can recognise Hypocrea species. Hypocrea stage is formed under special conditions, mostly in sutropical and tropical forests.


sabrina sarrocco voted for Trichoderma:

because its older and more "friendly"


Nagamani Adusumilli voted for Trichoderma:

The name Trichoderma is more familiar among scientists and industry than the name Hypocrea. Even though the teleomorphic name (Hypocrea)is supposed to be retained according to ICBN, it may lead to confusion as the name Hypocrea is not known to many as the sexual stage of the Trichoderma.


Monika Schmoll voted for Trichoderma:

My feeling is that the scientific community only hesitantly turned to Hypocrea and some scientists still reject it alltogether. Also the long history of Trichoderma in industry speaks for this name.
In my opinion the best way would be to use the name with which the isolate of interest has been described first, but that is not an option here I guess.


Lakshman Prasad voted for Trichoderma:

This is an already known and popular name among the world community i.e. scientists, farmers and industrialists etc.
Threfore, its application as Biocontrol agent will be proliferate very fast.


pratibha Sharma voted for Trichoderma:

Trichoderma needs to be retained ,since till today scientific community is well aware of Anamorphic stage as Trichoderma and Teleomorphic stage as


Nassapat Boonvitthya voted for Trichoderma:

I think it is widly used than Hypocrea and it is also give the honour to Reese who studied extensively on this fungus.


Truong Ngon voted for Trichoderma:

I think it was used long time ago, so it is easyto remember.


David Mwongera Thuranira voted for Trichoderma:

The generic name Trichoderma has been widely used in agriculture and biotechnological applications of the genus. The name is well known by the industry and products e.g biopesticides in agriculture have always been promoted or marketed as having Trichoderma as the active ingredient. Changing the name is likely to cause confusion in the industry and negatively affect dissemination of Trichoderma based technologies especially in Agriculture.
Though exclusive use of Trichoderma would neccessiate more numerous combinations, my opinion is that we retain the name Trichoderma for the sake of consistency as far as its industrial applications are concerned.

Rommel Vega voted for Trichoderma:

Trichoderma is older (1794) than Hypocrea, i.e. basically it has priority of publication, a much higher number of citations in applied microbiology and biotechnology due to the wide use in economic applications and considerations; exclusive result of isolation and most culture work and higher degree in morphological variation in some groups of the genus.


Gary Samuels voted for Trichoderma:

It is unfortunate that the Melbourne Botanical Congress force us to chose between two well established names, Hypocrea and Trichoderma. Mssrs. Jaklitsch and Gams argue for adopting the younger name, Hypocrea, over Trichoderma. I disagree for the following reasons.

1. Trichoderma is much more established in the biological and technological literature, including patents. In spring of 2011, before I retired and while I still had access to SCOPUS, over 8000 records were returned when Trichoderma was the key word. Only 1200 were returned with Hypocrea as the key word.

2. The rate of discovery of new Trichoderma species is phenomenal. In 1969 there were about 9 accepted species; in 1991 only about 40; today there are about 175 described species. All of these species are well characterized and represented in GenBank by two or more diagnostic sequences. Identification of an unknown Trichoderma using DNA sequences is very easy, in part thanks to the ICTF web site.

3. There are about 460 species of Hypocrea in Myco Bank. The vast majority of these have not been reported since they were described and when they were described, the descriptions were not done in any critical way. There is considerable homoplasy in morphology of Hypocrea: species we now know to be unrelated are morphologically undistinguishable. It is possible to apply old names to new collections but there is often doubt about the exact application of that name. Many of the earliest described species of Hypocrea belong in other genera. For example, MJ Berkeley described or participated in the naming of about 60 species of Hypocrea in the mid 19th century. These are some of the oldest names in the genus. Of these 60 approximately half (29) belong to other genera. One can only imagine the percentage of 'errors' in the genus Hypocrea as a whole.

4. Previously described species of Hypocrea need not be lost. A truly thorough taxonomist must take into consideration the whole organism and possible old names. The oldest names are in Hypocrea and, thanks to a nomenclatural procedure 'epitypification' old names can be characterized by modern techniques even if the type specimen of the old name is not the same species as the recent collection that is used in epitypification.

5. Most people are never going to see a Hypocrea collection. Trichoderma cultures are among the most common in the environment, including soil, endophytes and bulding materials.


Zafari Doustmorad voted for Trichoderma:

In addition to priority of Trichoderma to Hypocreqa by this name, this fungus are very know for poeple in differrent deciplines


Luis Galarza voted for Trichoderma:

All the information talk about the Trichoderma species


Matteo Lorito voted for Trichoderma:

Trichoderma is not only a nice microbe to study at genome level, but it is also and mainly a tool for farmers and industry. Without the last, most of the funds invested in basic research on Trichoderma research probably would have gone to other subjects. I am glad that most of the community is voting in favour of Trichoderma, probably aware that a "disruption" will be only limited to name use, while the opposite could be a lot more deleterious. Interestingly there seems to be no "arguments" against the exclusive use of Hypocrea, while the impact would not be only on the scientific community.


Sun Jun voted for Trichoderma:

When botanist name a new seed plant in species level, he usually not use the pollen feature, though they are the same plant but in different life stage; the same things like the Trichoderma and Hypocera, besides this, I think that Epigenetics study will revel the detail relationships between Trichoderma and Hypocera in the coming future!


Thibaut Robiou du Pont voted for Trichoderma:

Trichoderma is the most used name and as you said, most present in number of citations.


Mauricio Nunez voted for Trichoderma:

Becouse is more popular as biocontrol agent, whit greath consideration on biologocal control of plant disease reserchers...


Prabhakaran Narayanasamy voted for Trichoderma:

While using for industrial and agricultural applications its very important to have unique name. Most of the time we use to get Trichoderma species only from soil sample.


Gholam Reza Salehi Jouzani voted for Trichoderma:

"Tichoderma" is more familiar in the literature, is more available and also more diverse


Gary Harman voted for Trichoderma:

I dislike exclusive use of either name. Many strains of Trichoderma have no known perfect stage, and so Trichoderma more accurately describes those strains. Hypocrea can be using in parentheses. However, the taxon Tricoderma is improper, it seems to me, for studies involving strains where the perfect stage is known. I oppose automatically using one or the other.
Gary Harman


Temesgen Mulaw voted for Trichoderma:

More publications are available with the name trichoderma and almost all published papers using the name hypocrea do also indicate the anamorph-typified name (Trichoderma) so easy to understand. But it is a good decision to use one name to over come most readers confusion specially for those who do not know very much about trichoderma.
I therefore prefer to use Trichoderma as the standard name for all purposes.
Thank you,


Enrique Monte voted for Trichoderma:

1) It is the oldest name
2) The conidial state is more common
3) When I characterized biocontrol strains of T. harzianum only one was Hypocrea lixii. Why I have to describe as H. lixii most of the T. harzianum strains with no relation (at least until now) with this Hypocrea sp.
4) If I work with anamorphs at a genetic level, I prefer to say in the publications that I have worked without sexual variability. Hypocrea could bring confusion in this case.


Chulong Zhang voted for Trichoderma:

I think the aims of classification and identification is to serve the overwhelming majority of the people. Trichoderma is more wide use and easier for economic application.

Muthu Kumar Arunachalam voted for Hypocrea:

Hypocrea is the actual sexual part of this fungi


sukumar debnath voted for Hypocrea:

ocurence of teleomorphic (Perfect)and anamorphic(imperfect) stage in fungi is an evolutionery events and the connection between two stages have been recognised by molecular methods.

Hence there is a need to evolve a mechanism to record the natural occurrence of this unique variability in fungi with particular reference to Trichoderma.


Marc voted for Hypocrea:

I am generally opposed to naming fungi for anamorphic structures that often turn out to be plesiomorphic characters, when teleomorphic names are readily available. I am not sure whether Trichoderma in the current sense will eventually need to be further subdivided or thoe fungi that have a Trichoderma anamorph will eventually elevated to a higher taxon rank. So I can only recommend t stick to teleomorph names especially if they circumscibe a clear cut taxonomic entity.


Walter Gams voted for Hypocrea:

I favour Hypocrea, as I see that an increasing number of mycologists (also applied) are getting used to this name, which as teleomorph always had nomenclatural precedence so far. There is little cogent reason to change all the species to Trichoderma.


Juan Pablo Mac Donald voted for Hypocrea:

Considering simplicity and the fact that it is the teleomorph name, Hypocrea seems scientifically more appopriate. Informal use of Trichoderma as a name in applied and technological contexts need not be affected by what the underlying scientific name would be (i.e. It may be informally called Trichoderma but scientifically retain the Hypocrea genus).


Walter Jaklitsch voted for Hypocrea:

As it is clear from our Critical Response to the Amsterdam Declaration I am against a change to a unified nomenclature, because there will be always somebody who will have a problem with one name, as there is no consensus among users of fungal names. If the change is necessary I stick to teleomorph precedence in naming holomorphs.
