  • Mycological Notes 11: Boletus Edulis in Canterbury Jerry Cooper, July 2012
    Mycological Notes 11: Boletus edulis in Canterbury Jerry Cooper, July 2012 Probably most mycologically minded New Zealanders know about Boletus edulis in Christchurch. Wang et al (1995) reported its occurrence with a number of host trees across the City and a single collection from Lake Pukaki with Birch. A well-known stronghold is with Quercus robur (Oak) in Hagley Park where it occurs with a range of other fungi. Wang et al speculate that B. edulis arrived with early European settlers into Christchurch and spread, perhaps with nursery plants in some cases. Research by Stringer et al (2002 & pers.comm), indicates that the old oak trees in Hagley Park arrived as living plants in half-barrels on-board ship. Thus the soil+fungus+roots+tree were shipped together. Even the possible source of the nursery near Bagshot in the UK has been traced. Similar shipments were apparently made to Nelson and planted in parks there. Recently there are reports of the fungus from various plantations in North Canterbury. In New Zealand the bolete is relatively immune to attack by fungous gnats, unlike its home range where most specimens rapidly become a maggot nursery. In recent years I have noticed more damage, so either the associated fungus gnat has arrived, or local species have developed a taste for it. The fungus has also been introduced/arrived with Pinus plantations in South Africa, Zimbabwe, and Chile. Wang et al also recognised that the name ‘Boletus edulis’ has been used in a broad sense by some, with morphological/host differences recognised as separate species by others.

    MushRumors The Newsletter of the Northwest Mushroomers Association Volume 24, Issue 2 August - October 2013 Record Rainfalls Hit Washington! The Perfect Myco - Storm! In the aftermath of one of the most memorable spring mushroom seasons in recent memory, highlighted by perhaps the best morel onslaught ever before seen, the rains of June which led to these ideal conditions, yielded to what would be a warm, dry July and first half of August. Then it happened. Unlike last year, when Photo by Daniel Viney high pressure dominated Washington’s weather, dismissing any and all precipitation for a record 88 consecutive days, on August 10, 2013, a very unusual weather pattern produced intense thunderstorms all across the region, dousing both the eastern and western slopes of the Cascades and dumping nearly 6 inches of rain on some of the alpine passes. In addition to causing mudslides that would close some of the highways leading over those passes, the storms had another profound effect: fall mushrooms, which have not enjoyed any truly favorable conditions in our area’s high country since 2009, were awakened with a vengeance. Within a week of these storms, a full array of mushrooms King boletes, emerging in droves, in August! rarely seen at these elevations until late September, were in stunning abundance. King boletes, admirable boletes, gypsy mushrooms, and shrimp russulas fruited in staggering numbers. As a result of temperatures holding into the mid- 70s, the only real challenge was getting to the boletes before the worms could devour them. The heat greatly accelerated the life cycle of the offending flies.

Several studies have reported that mushrooms accumulate many potentially toxic elements (PTEs) such as Hg, Pb, and Cd, which may lead to adverse effects. Therefore, in this preliminary study, an assessment of the potential of a microbial assay for risk assessment (MARA) for ecotoxicological testing of both dried samples of fruiting bodies of King bolete collected from several sites of Poland and water extracts of mushrooms being tested were analyzed. An evaluation of MARA response in Boletus edulis extracts was performed to identify their toxicity and then, using the same samples, instrumental determination of 10 elements (Al, As, Cd, Citation: Zubaidi, M.A.; Proch, J.; Cr, Cu, Fe, Hg, Ni, Pb, and Zn) was performed. In general, the MARA responses indicated that the Konieczny, P.; Tomczyk, Ł.

The present study determined the sorption characteristics of Bulgarian penny buns (Boletus) for eight water activities in the 10 % - 90 % range and at three temperatures, of 10 °С, 25 °С and 40 °С. The coefficients of the modified Oswin, Chung-Pfost, Halsey and Henderson models were obtained statistically. The modified Halsey model is recommended as a description of adsorption and desorption isotherms since it corresponds to the criteria for model assessment and suitability. Via BET model linearization, the values of the monolayer moisture content for water activity of aw > 0.5 and temperatures of 10 °С, 25 °С and 40 °С were established. The approximate physico-chemical composition of Bulgarian penny buns (Boletus) – moisture content – 10.80 %, protein – 32.23 %, carbohydrate - 0.99 %, fat – 6.62 %, ashes – 6.20 % - was also determined.
