  • MODELIST23.Rtf 29/5/15 the BMS
    MODELIST23.rtf 29/5/15 The BMS Travelling Exhibition of Fungus Models: A Brief History Henry Tribe In 1987 the British Mycological Society arranged a Fungus Modelling Workshop in Pershore, Worcs. given by Dr S.Diamandis from Greece who specialised in latex moulding techniques. One of the participants was Mrs Eileen Chattaway of Charmouth, Dorset and by 1996 she had made some 35 models of fungi. These she kept at her home but she thought that they would be more useful if she loaned the majority of them to the Society for the purposes of a Travelling Exhibition to the general public. As Publicity Secretary of the BMS at the time, arrangements fell to me. The first exhibition was at the Royal Literary and Scientific Institution in Bath. Eileen herself brought her models to Bath, carefully wrapped for transit, but we realized following the exhibition that individual boxes for each model were needed for transit purposes. The President, Steve Moss, agreed that this was necessary and 29 individual boxes were ordered from Dauphin Display Ltd of Oxford. Their Managing Director went to Charmouth to measure the models and found that four standard box sizes sufficed to fit them. Each box was made of acrylic sheet on a medium density fibre (MDF) base and could serve as an exhibition container inside a museum cabinet. The cost was £ 949 plus delivery (£ 94) and included four large hardboard boxes inside which the acrylic boxes fitted. A further charge of £ 88 was made for the visit to Dorset. Total cost = £ 1131. Steve Moss also asked Eileen Chattaway to value the models for insurance purposes and this came to £ 2825.

  • MUSHROOMS of the OTTAWA NATIONAL FOREST Compiled By
    MUSHROOMS OF THE OTTAWA NATIONAL FOREST Compiled by Dana L. Richter, School of Forest Resources and Environmental Science, Michigan Technological University, Houghton, MI for Ottawa National Forest, Ironwood, MI March, 2011 Introduction There are many thousands of fungi in the Ottawa National Forest filling every possible niche imaginable. A remarkable feature of the fungi is that they are ubiquitous! The mushroom is the large spore-producing structure made by certain fungi. Only a relatively small number of all the fungi in the Ottawa forest ecosystem make mushrooms. Some are distinctive and easily identifiable, while others are cryptic and require microscopic and chemical analyses to accurately name. This is a list of some of the most common and obvious mushrooms that can be found in the Ottawa National Forest, including a few that are uncommon or relatively rare. The mushrooms considered here are within the phyla Ascomycetes – the morel and cup fungi, and Basidiomycetes – the toadstool and shelf-like fungi. There are perhaps 2000 to 3000 mushrooms in the Ottawa, and this is simply a guess, since many species have yet to be discovered or named. This number is based on lists of fungi compiled in areas such as the Huron Mountains of northern Michigan (Richter 2008) and in the state of Wisconsin (Parker 2006). The list contains 227 species from several authoritative sources and from the author’s experience teaching, studying and collecting mushrooms in the northern Great Lakes States for the past thirty years. Although comments on edibility of certain species are given, the author neither endorses nor encourages the eating of wild mushrooms except with extreme caution and with the awareness that some mushrooms may cause life-threatening illness or even death.

Radiocaesium behaves similarly to potassium in soil-plant systems and is easily absorbed by plants. It is important to understand how 137Cs behaves in different ecosystems in order to minimize the risk toward humans. The aim of this study was to determine how potassium fertilization influences radiocaesium content in different forest plants and fungi.
