From the President I’m very pleased to announce that we have forged a new collaboration with market leading magazine Mushroom Business, the latest copy of which you are now holding in your hands. As you know, the ISMS informed its members in the past through our Mushrooms International Newsletter in print, and from 2006 – 2008 as an e-newsletter. For several reasons, this publication has been discontinued. In recent years, ISMS has worked with the publisher of Mushroom Business (Global Roel Media) to our mutual benefit. This is not surprising, as both parties further the growth of the international mushroom industry through independent dissemination of information on a global scale. Through its vast readership base and firm network within the worldwide industry, we believe that Mushroom Business constitutes a stable, readable and informing plat- form for the ISMS messages and news, besides or other publications in print and online. So from now on, you will find ISMS contributions on this page, informing you on everything we are up to. If you have any news you want to share, please mail to the editor:

In September 2013 the executive committee of ISMS has changed (
http://www.isms.biz/council/); a new secretary, dr. Christine Smith and a new treasurer, dr. Johan Baars (Wageningen University and Re- search Centre, in short “WUR”). I am thus writing my very first column for ISMS News. First, a short introduction; I have a broad experience in mushroom research but I am mainly working as a scientist on genetics and strain development (predominantly Agaricus bisporus) and on substrate utilisation by mushrooms. As such I am also involved in dis- cussions on strain protection of new Agaricus bisporus varieties. This is not a trivial matter. Over the last 50 years a lot of progress has been made with respect to the cultivation of button mushroom. Pre- paration of compost has improved tremendously. Also climate control and the design of mushroom farms has seen great progress (and many other things). However, the last decades, no major innovations to the system are seen. One resource seems to be rather unutilised: the gene- tic diversity of mushroom strains.

Mushroom strains that are currently used in the industry are very closely related and over the past 30 years virtually no genuine new strains have entered the market (Heirloom and Brawn being the excep- tion). This is, at least partly, due to difficulties to protect new varieties. Although protection is possible by applying for Plant Patent in the USA and Breeder’s Right in the European Union (and similar legal construc- tions in other countries), it appears to be easy and cheap to develop essentially derived strains (EDV’s) from protected strains. EDV’s are generated (mainly) generated from protected varieties and can out- compete the first variety thus reducing the return of investment of the first breeder. For this reason the UPOV guidelines have been adapted

and the breeder of an EDV has to negotiate with the first breeder for a licence.
Since it is not always clear how to define an EDV, a working group has been formed to reach a consensus that will be expressed in a position paper. Members of this group are major breeders/spawn companies in Europe (Amycel, Sylvan, Limgroup and Lambert Spawn) and resear- chers from France and the Netherlands. Next to a position paper on the EDV definition, the working group will also publish a peer reviewed scientific paper on the life cycle of the button mushrooms with special focus on meiotic events and the gene- ration of basidiospores. From this it can be derived in detail how EDVs are generated. Both papers are relevant for new varieties and have no consequences for existing varieties. For those who are interested in learning more about this topic, I would like to refer to an article of dr. Anton Sonnenberg in Mushroom Business nr. 60 (August 2013) and an article by dr. Jean Michel Savoie in Bulletin nr. 10 (January 31th, 2014) of the WSMBMP.
ISMS Congress 2012 Things are coming together nicely for the 18th ISMSC in fascinating Beijing, China on August 26-30, 2012. This event will be the highlight for the mushroom indus- try internationally next year. The main purpose of this Congress is to promote the development of mushroom industry as well as to present the latest developments. In addition to the scientific communication, new varieties, new products, new technolo- gies and latest publications will be showcased. The theme of the Congress is Mushroom and Health, which will focus on (I) The development and prospect of industrial situation; (II) Production and technology; (III) Nutrition and health. The Congress will consist of keynote lectures, plenary sessions, oral and poster presentations. Key note speakers will include Dr. Anton Sonnenberg (Breeding for the Future), Dr. Shiuan Chen (Protective effects of Agaricus bisporus), Prof. Yu Li (Chinese mushroom industry) and Dr. Ian R. Hall (Mycorrhizal mushrooms). Farm visits are planned to the Tongzhou District on August 29. The 18th Congress will be held at Beijing International Convention Center (BICC), which is located close to the main venue of the 2008 Olympic Games and touristic highlights. This is an event not to be missed, so get it in your diary and make sure you’ll be part of it!
Crowd control: a good investment
About the ISMS The International Society for Mushroom Science seeks to further the cultiva- tion of edible (including medicinal) fungi. It is non-political and non-profit making. The objectives of ISMS are the dissemination of information on new

Mushroom quality quickly deteriorates if they are crowded together and less air can flow past. Moisture, especially, and CO2 are not removed so well which has a harmful influence on mushroom development. The mushrooms start to mature too soon, with negative effects on the firmness and colour. The result is mushrooms with elongated, weak stalks, a stage of maturity ranging from mildly to strongly veiled and an off-white colour (see photo). There are numerous influential factors, but this tip concentrates on the picking method. Mushrooms are never naturally distributed uniformly over the bed. So, when the flush starts it is important to remove enough mushrooms from places where cluster forming is seen or crowding. This creates space for the other mushrooms to grow and develop into firm examples with the required cap size. Removing the crowded mushrooms from the beds in the first two days means a long-term in- vestment in the flush as the picking performance at this stage can be some 10 kg/hour lower, because harvesting small mushrooms is more time consuming. These mushrooms come with high picking costs, but the gains will be made on days three to five of picking. By now, the mushrooms have more space and can be picked more quickly and they weigh more so the picking performance will be clearly higher than normal. The final score will be a slightly hi- gher than average picking performance over the duration of the entire flush. More important- ly, mushroom quality will be better. This means a better class I (no longer at the lower limit of the quality range) and a higher percentage of quality I. This higher percentage of quality I depends to some degree on the initial situation, but in practice a rise of between 2 and 6% is possible. It is essential to instruct the pickers properly, and check their performance, so that the right number and the right mushrooms are removed from the beds in the all -important

developments and the science of mushrooms and to stimulate exchange of new ideas between growers and scientists around the world. ISMS sponsors a major international congress on mushrooms, which is held every 3-5 years. Other events are endorsed and supported by ISMS working with national committees. The Society is governed by a council which includes a member appointed by each Corporate Member and six members elected by ballot of the individual members. The Council elects the President, Vice-President, Secretary, Treasurer, as well as the past president to be the Executive Com- mittee.
