Website: http: //www.rirdc.gov.au Published in March 2004 Printed on environmentally friendly paper by Canprint ii Foreword Internationally there is increasing demand for both European and Asian specialty mushrooms. In particular: Maitake, a quality edible and medicinal fungi, and Morel, a fungal delicacy which is currently wild harvested. Australia is well placed to enter the market and meet demand due to its proximity to Asian markets, its multi-cultural heritage and export links with USA, Europe and Asia. Both Maitake and Morel provide opportunities for new entrants to the national mushroom growing industry. Maitake research focussed on (i) developing a technique for the cultivation of maitake based on the Japanese bag method of cultivation; (ii) determining levels of substrate additive which enhance efficient substrate colonisation and primordia initiation; (iii) identifying maitake isolates with the best commercial potential; (iv) providing the industry with a commercially viable maitake production system. Morel research focussed on (i) providing the industry with a wide range of Tasmanian Morel isolates; (ii) identifying Tasmanian isolates to species level; (iii) investigating triggers for sclerotia production; (iv) comparing the production of sclerotia by Tasmanian isolates with overseas reference isolates; (v) selecting Tasmanian isolates which produce the largest sclerotia for further research. Building on the successful R&D outcomes from RIRDC projects DAT-30A (The development of commercially viable culturing and fruiting systems for some Asian specialty mushrooms) and UT-12A (Preliminary investigation on "French" black morel cropping) this project identified suitable Maitake isolates for commercialisation, determined additives to ameliorate eucalypt sawdust for substrate, and trialed a production technique. A large collection of Morel isolates was obtained and preliminary studies on their ability to produce sclerotia, a precursor to fruit body production, were completed. Extensive literature reviews about Maitake and Morels summarise both published and anecdotal information. This project was funded from RIRDC Core Funds which are provided by the Australian Government. Funding was also provided by HAL and industry partner Huon Valley Mushrooms. This report, a new addition to RIRDC’s diverse range of over 1000 research publications, forms part of our Asian Foods R&D Program, which encourages development of a viable industry in Australia.

    1 Lettre d'informations n° 21 – 2017/05 Rencontres mycologiques 2017 Catherine PAYANT La Société Mycologique de Rennes organise cette année les rencontres mycologiques inter associatives. Elles se tiendront le dimanche 14 mai à partir de 9h30 à Néant-sur-Yvel et regrouperont l’Association Mycologique Ploemeur Morbihan (AMPM), le Groupe Mycologique Nazairien (GMN) et bien sûr la SMR. Le RV est au parking de Folle Pensée (Fontaine de Barenton), commune de Paimpont à 10h . De là, balade pédestre accompagnée et commentée sur les chemins enchantés de la Forêt mythique de Paimpont sous la conduite de guides. Vers 12h départ des voitures en cortège pour Tlohan près de Néant sur Yvel, à environ 7 km de la Fontaine de Barenton. Pique-nique près d'un étang, précédé d'un apéritif offert par la SMR. Pensez à apporter vos tables et chaises. En cas de mauvais temps, sur ce lieu un vaste abri couvert est à notre disposition mais les dieux de la forêt seront avec nous ! L'après-midi peut être libre ou balade vers l'Arbre d'or et, ou visite de la très jolie église de Tréhorenteuc. 22 avril 2017 : dans les dunes Plouharnel (56) Dimitri BACRO Plusieurs membres de l’association mycologique de Ploemeur Morbihan sont venus nous rendre une petite visite à l’heure du pique-nique. Nous avons pu consulter un petit inventaire des champignons récoltés dans les dunes. Parmi les espèces couramment rencontrées, une morille plutôt méridionale, Morchella dunensis . Et en dépit des conditions climatiques proches de la sécheresse, nous en avons trouvé trois ou quatre, dont la première, énorme, avait séché sur pied à l’entrée d’un terrier de lapin ! (S’il est vrai que l’urine des diabétiques favorise l’apparition des morilles, voilà qui nous interroge sur celle des lapins.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Morchella fungi are considered a good source of protein. The ITS region was used to identify Morchella isolated in the northern region of Iran. The isolated fungus was very similar to Morchella fluvialis. M. fluvialis was first isolated in Iran. Dried biomass of M. fluvialis contained 9% lipids and 50% polysaccharides. Fatty acid profiles of lipids of M. fluvialis are mainly made up of linoleic acid (C18:2) (62%), followed by palmitic acid (C16:0) (12%). Testosterone (TS) was also detected (0.732 ng/dry weight biomass (DWB)) in the hormone profile of this new isolated species. Then, various protein and carbon sources as variable factorswere applied to identify the key substrates, which stimulated protein production using the one-factor-at-a-time method. Key substrates (glucose and soybean) were statistically analyzed to determine the optimum content of the protein and DWB accumulation using response surface methods.
