The relative configuration of oudemansin have been determined by X-ray analysis. The antibiotic exhibits strong antifungal properties and inhibits respiration in fungi, cells of the ascitic form of EHRLICHcarcinoma, and rat liver mitochondria. Recently we elucidated the structures of two antifungal antibiotics from cultures of Strobi/urus tenace1/us2'31. Strobilurin A (1) has the same molecular formula Cs,;H,903 as mucidin, an antifungal compound isolated from Oudemansie/la mucida by VONDRACEK et a/.4'51 However, in contrast to oily, achiral 1, mucidin is crystalline (m.p. 51-53°C) and optically active ([x]546 +33')". In this publication we describe the isolation and structural elucidation of oudemansin (2), a new antibiotic from Oudemansiella mucida showing similar biological activity to 1. Results and Discussion 1. Fermentation, Isolation, and Physico-Chemical Properties Mycelial cultures of Oudemansie/la mucida obtained from spore prints were grown on yeast extract- malt extract-glucose (YMG) medium as described in the experimental section. -
LUNDY FUNGI: FURTHER SURVEYS 2004-2008 by JOHN N
Journal of the Lundy Field Society, 2, 2010 LUNDY FUNGI: FURTHER SURVEYS 2004-2008 by JOHN N. HEDGER1, J. DAVID GEORGE2, GARETH W. GRIFFITH3, DILUKA PEIRIS1 1School of Life Sciences, University of Westminster, 115 New Cavendish Street, London, W1M 8JS 2Natural History Museum, Cromwell Road, London, SW7 5BD 3Institute of Biological Environmental and Rural Sciences, University of Aberystwyth, SY23 3DD Corresponding author, e-mail: [email protected] ABSTRACT The results of four five-day field surveys of fungi carried out yearly on Lundy from 2004-08 are reported and the results compared with the previous survey by ourselves in 2003 and to records made prior to 2003 by members of the LFS. 240 taxa were identified of which 159 appear to be new records for the island. Seasonal distribution, habitat and resource preferences are discussed. Keywords: Fungi, ecology, biodiversity, conservation, grassland INTRODUCTION Hedger & George (2004) published a list of 108 taxa of fungi found on Lundy during a five-day survey carried out in October 2003. They also included in this paper the records of 95 species of fungi made from 1970 onwards, mostly abstracted from the Annual Reports of the Lundy Field Society, and found that their own survey had added 70 additional records, giving a total of 156 taxa. They concluded that further surveys would undoubtedly add to the database, especially since the autumn of 2003 had been exceptionally dry, and as a consequence the fruiting of the larger fleshy fungi on Lundy, especially the grassland species, had been very poor, resulting in under-recording. Further five-day surveys were therefore carried out each year from 2004-08, three in the autumn, 8-12 November 2004, 4-9 November 2007, 3-11 November 2008, one in winter, 23-27 January 2006 and one in spring, 9-16 April 2005. -
Megacollybia (Agaricales)
Rep. Tottori Mycol. Inst. 45 : 1–57, 2007. Megacollybia (Agaricales) KAREN W. HUGHES1, RONALD H. PETERSEN1, JUAN LUIS MATA2, NADEZHDA V. PSURTSEVA3, ALEXANDER E. KOVALENKO3, OLGA V. MOROZOVA3, EDGAR B. LICKEY 4, JOAQUIN CIFUENTES BLANCO5, DAVID P. LEWIS6, EIJI NAGASAWA7, ROY E. HALLING8, SEIJI TAKEHASHI9, M. CATHERINE AIME10, TOLGOR BAU11, TERRY HENKEL12 Abstract The genus Megacollybia, originally proposed for M. (Collybia) platyphylla, has traditional- ly been treated as monotaxic. A phylogenetic reconstruction based on ITS rDNA sequences indicates that several species are involved, with strong phylogeographic signal. Although morphological characters are largely qualitative, examination of basidiomata suggests that specimens included in discrete clades can be distinguished at the species level. On these bases (phylogenetic, morphological), several new taxa are proposed: M. clitocyboidea, M. texensis, M. fusca, M. subfurfuracea, M. rodmani (with f. murina) and M. marginata. Tricholomopsis fallax is transferred to Megacollybia; M. platyphylla remains the type species of the genus but appears to be restricted to Europe, Scandinavia and western and central Russia.

Recent insights from -omics data revealed a high functional diversity of wood-decay strategies, especially among the traditional white-rot and brown-rot dichotomy. We examined the mechanistic bases of wood-decay in the conifer-specialists Armillaria ostoyae and Armillaria cepistipes using tran- scriptomic and proteomic approaches. Armillaria spp. (Fungi, Basidiomycota) include devastating pathogens of temperate forests and saprotrophs that decay wood. They have been discussed as white-rot species, though their response to wood deviates from typical white-rotters. -

The Economy of the Tyle State
SAVAGE BUSINESS – The Economy of the Tyle State One would imagine that an invasion by hundreds of thousands of barbarians would have a catastrophic effect on a region’s economy. However, this presumption has been challenged in recent years by the archaeological and numismatic data emerging from the territory which fell under the control of the ‘barbarian’ Tyle state in eastern Thrace during the 3rd c. BC. The traditional description of the Celtic tribes who arrived in this area has been one of ‘thirsty savages’ or ‘gangs of mercenaries’ (latest Emilov 2007, 2010), and we have been repeatedly informed that ‘their aim was not to settle, but money and booty which could be aquired in different ways … by attacking wealthy cities, and by ravaging the countryside’ (Nixon 1977, cited by Mitchell 1993; most recently Emilov 2010). However, repeating a simplistic stereotype does not make it true, particularly when the depiction of a culture directly contradicts all the available archaeological and historical evidence. In this case the facts tell a rather surprising tale – a barbarian invasion that brought political stability and economic prosperity in its wake. Eastern Thrace – 3rd c. BC THE ‘BARBARIAN BOOM’ Recent archaeological evidence has clearly shown that no destruction accompanied the Celtic migration at the beginning of the 3rd c. BC and, even more surprisingly, in none of the regions which fell within the limits of the Celtic Tyle kingdom can an economic downturn be detected (Lazarov 2010: 110). Indeed, it is precisely in the wake of the establishment of the Celtic state that the main Hellenistic economic centres in eastern Thrace and the Black Sea coast such as Kabyle, Mesambria and Odessos flourished and trade boomed. -

I first came across this species after moving into Llandogo in 1998. In the following years I noted their presence at various Glamorgan Bird Club Swift Project Update 19 localities between Llandogo and Lower Penallt on the Gwent side of the river. I haven’t extended my searches beyond this. © Chris Hatch Living Levels: Wild Watch 20 It is generally accepted that the typical flight period for Gomphus vulgatissimus extends from May into early July. In my experience, along the Wye, they first appear about mid-May (24th May in 2016 and 15th May in 2017) and can then be seen on and off through A response to Colin Titcombe’s article on mistletoe hosts 21 June and into early July. I say ‘on and off’ because, once emerged, they vacate the river until they become sexually mature. -

The survey was conducted in the period between 2014 and 2020. After prior informed consent, 709 local residents from 32 settlements were interviewed. The interviews with the local population were conducted using the "face to face" technique with the help of pre-prepared original questionnaires. The study presents quantitative ethnobotanical information on the use of medicinal plants in the study area. The results were analyzed using quantitative indices: Respondent Consensus Ratio (FIC), Loyalty Level Index (FL) and Significance Value Index (IVs). A total of 332 species of medicinal plants belonging to 250 genera of 90 families have been identified for the region of the Northern Black Sea Coast. The largest number of citations are registered for the use of medicinal plants for culinary purposes and for use in human medicine. The use of medicinal plants in other household applications has been studied. Keywords: FIC, FL, IVs, Northern Black Sea coast Introduction Globally, due to the trend of globalization, traditional knowledge, including that of medicinal plants, is declining and some of it is irretrievably lost.
