Descriptions are given of M. pseudocorticola, M. meliigena, M. juniperina, M. hiemalis, M. erubescens, and M. alba. Illustrated liberally with excellent colour photos of f/bs and microscopic characters. (4 refs.) J-J Wuilbaut (pp. 19-29) [French] Series of colour photos of species found during the mild winter of 2011-12 in western Hainaut, Belgium. Cortinarius trivialis, Tricholoma fulvum, Lactarius vietus, Russula gracillima, Inocybe dulcamara, Cortinarius cohabitans, Lactarius pubescens, Lactarius glyciosmus, Tricholoma cingulatum, Hygrophorus discoxanthus, Tricholoma psammopus, Sarcoscypha coccinia, Chondrostereum purpureum, Tubaria hiemalis, Phaeogalera dissimulans, Strobilurus esculentus, T Stijve (pp. 30-33) [French] Account of a fruiting of Inonotus hispidus on an ancient ash tree in a square in the old part of Vevey, Switzerland. The species used to be used for dying but is also thought to have medical uses. Illustrated with colour photos. Boston Mycological Club Bulletin – Vol 67, No 1, 2012 Abstractor – Anne Andrews Millman L (p.3) [English] Report of a find of Jaapia argillacea, under a log, on New Year’s Day. The distinctive spores are described. Wolfe B (pp. 7-10 & 22) [English] Part II of report of a study of the evolutionary origins of mushroom mutualism. Mycorrhizal Amanita species are descended from free living saprobes that decompose dead organic matter. They have lost the genes which would enable them to break down cellulose. These are no longer needed when the fungus obtains the sugars it needs from the roots of the trees it grows with and indeed they might endanger the tree roots or trigger defence systems that would reject the fungus. Detailed analysis suggested that loss of these genes may be a prerequisite rather than a consequence of the evolution of symbiosis. The genome of Amanita thiersii, a free living species in grassland, has been sequenced. The next step is to sequence the genome of an ectomycorrhizal species for comparison. Dawson J (pp.15-17) [English] Biographical information about Alexander H Smith and his wife Helen V Smith and William Judson Boone, eminent early American mycologists whose names are commemorated in Boletus smithii and Calvatia booneana. Goldhor S (pp. 23-37) [English] The taxonomy of Morels is confused and unclear. It is difficult to predict when, where or how much they will fruit. Morel hunters tend to be obsessive. The edibility/toxicity of false Morels ( Verpas, Hevella and Gyromitras) is discussed. Other fungus-related topics are discussed in this article. Boletus - Vol. 32, No. 2, 2010 Abstractor – Ray Tantram (in German) Nüske A, Hirsch G. (pp. 74-79) Tyromyces kmetti, a rare poroid species, was recorded for the first time in Thuringia, Central Germany in October 2009. This species, which grows on dead deciduous wood of several tree species, mainly in colline and submontane regions, is described. Spore measurements taken compare well with those from other authors. Records for the last decade show an increase for this species, hitherto mostly found in Southern Germany, suggesting a possible spread. A colour plate shows the fungus in situ, and a line drawing its characteristic hyphal structure. Tables show spore measurements quoted in the literature and records for Germany, Austria and Switzerland. A distribution map is included.http://forum.fungiworld.com ; http://www.wsl.ch/dossiers/pilze/swissfungi/verbreitungsatlas/datenbank_DE: (Status in 2009) (22 refs.) Ruske E; Dörfelt H. (p. 80-90) The lifecycle of the American Mahonia Rust, Cumminisiella mirabilissima and its expansion and distribution in Europe is discussed. Methodology and results are detailed. Several developmental stages described in the literature are compared with the authors’ observations, made over a two-year period. Some published opinions have been confirmed and disagreements discussed. The current study has also focussed on photographic documentation of the several rust development stages, with colour plates (in 3 tables) showing fungal structures on winter leaves, the generations of spermogonia, aecia and uredia on young leaves, and infestations on fruit. (24 refs.) Sänger H; Tüngler E. (p. 91-99) An investigation of the mycoflora on spoil heaps created by former uranium mining in Eastern Thuringia, has shown that 117 species have been added since 2005. This brings the overall total to 346. This consists of 8 genera and 11 species of Myxomycota, 32 genera and 14 species of Ascomycota, and 121 genera and 291 species of Basidiomycota. Mycorrhizal fungi still play an important role in these heaps many decades after mine closures. 81 species (23%) of total fungi belong in this group, with a further 74 species as saprobionts on wood, 32 species on wood and soil, and 24 species growing on soil only. Species not found include saprobionts growing on Pine cones, and those living on mosses and soils, also there are no root parasites present. The species recorded include 23 considered ‘endangered’ in Thuringia or in Germany as a whole. These species are colonising sandy coniferous forests, timber yards, clear-cut areas, forest clearings and semi-dry grasslands. Recording methods are explained, and species found listed. Colour plates show the greening of the Beerwalde mining area, Hygrocybe acutoconica, Leccinum duriusculum, and Tricholoma portentosum. A further plate shows how fungi are recolonising bare soil areas. A table lists endangered and protected species present. (12 refs.) Vesper A; Richter T. (p. 100-105) Careful investigation of a collection of Inocybes from Brandenburg showed these to be very similar, or identical to Inocybe rufuloides Bon ss. Bon. Macro and micro features are described, and compared to descriptions by Bon and other authors. Both features that agree and features that do not, point to some very closely related taxa. The particular difficulties of separating I. rufuloides from I. subporospora are discussed. Colour plates show I. aff. rufuloides, and two colour forms of I. subporospora. A photomicrograph shows spores of the latter species. Line drawings present spores, pleurocystidia, and cheilocystidia with paracystidia of Inocybe rufuloides. A table compares important characters of Inocybe rufuloides Bon ss. Bon and of I. subporospora with the material found in Brandenburg. (14 refs.)* Note* The J Stangl book is noted among the lit. refs. Rönsch P; Rönsch S; Reiher A; Otto P. (pp. 106-122) Xylaria delitschii forms stromata on buried fruits of Hornbeam. This species was initially found in Saxony-Anhalt and Hesse in 1868, and not recorded again until the present day. There is a close morphological and ecological similarity between this species and Xylaria oxyacanthae which grows on Haws, for which there are about 40 records held in Germany. The two species were compared with respect to their structural features, phenology, substrate specificity and DNA sequences. Subtle microscopic differences between the two were found when investigating spores, perithecia and rhizomorphs. Both normally develop anamorph stages with conidia from May until late autumn. Telemorphs, formed in autumn, were rarely found. In culture both species developed on both hosts, but Xylaria delitschii grew more strongly on Hornbeam substrate. DNA evidence highlighted 62 differences for 524 sequence positions in the ITS region of ribosomal nuclear DNA. Details of the two species, collection locations, and culture conditions are presented. Colour plates include location shots and in situ photographs of conidia, and perithecia from ripe stromata for both species, with photomicrographs showing asci and spores. Culture dish growth patterns are also presented. (26 refs.) Boletus - Vol. 33, No. 1, 2011 Abstractor – Ray Tantram (in German) Melzer A. (pp. 3-6) A first record for Germany of Psathyrella magnispora is described. It was collected in Saxony-Anhalt in dry calcareous grassland. Some confusion in handling previous collections resulted in misidentification as P. romagnesia despite the spores being too large for this species. Macro and micro features are detailed. This taxon is characterised by mainly medium-sized fruitbodies, with no striations on the cap, but a fugacious veil, frontal broadly-elliptical spores, cystidia with partially yellowish walls and by habitat. Six further points highlight differences from similar species. Hitherto this taxon has only been found in Spain, Austria and Hungary. Two colour plates show different collections of P. magnispora in situ, demonstrating ripening brown spores on pale gills. Line drawings show cheilocystidia, clavate marginal cells, pleurocystidia, spores and basidia. (7 refs.) Kleine J; Rönsch P; Rönsch S; Hampe F. (pp. 7-19) Three interesting, easily recognised
