紫杉菌属——中国新记录属

报道了口蘑科中国新记录属——紫杉菌属。并基于形态特征及分子系统学方法描述了中国新记录种粗壮紫杉菌,标本采自中国浙江省丽水市。该种的鉴别特征是子实体中型,菌盖浅黄褐色,中央黄褐色至深褐色,具有不连续的褐色锥状鳞片,菌褶直生,菌柄圆柱状,中实,基部略膨大,菌环以下污白色,具近似于盖上的锥状小鳞片,常脱落。菌环膜质,易脱落;担孢子椭圆形至宽椭圆形,表面具疣状纹饰,非淀粉质;褶缘囊状体和侧生囊状体缺失,菌盖鳞片由匍匐或半直立状菌丝组成,末端细胞圆柱状,无球针状囊状体,分支,具硬壳。     

Founder effect in a young Leccinum duriusculum (Schultzer) Singer population

The genetic diversity of a Leccinum duriusculum population growing under <20-year-old Populus alba on former farming soil was analysed from 1998 to 2001 and compared in 2000 to the two nearest populations found under >70-year-old P. alba. Genets were recognized using RAPD amplifications with three different primers, while their conspecificity was assessed by sequencing the nuclear ITS and mitochondrial large ribosomal subunit. The young population was colonized by a large genet that persisted from 1998 to 2001 (most distal sporophores were 10.4 m apart in 2001) and a second genetically related genet appeared in 2001. Five and six genets, respectively, of smaller size were found in the two other populations, while the investigated area was slightly smaller (72.25 m2) and the three populations were strongly divergent genetically (>33%). The genetic uniformity, as well as the high speed of radial growth of the lasting genet under <20-year-old P. alba (radial growth: 1 m/year), are interpreted in the framework of a founder effect. The slow recruitment of genets is proposed to lower the intraspecific competition and to entail large, fast-growing genets. The differences from ectomycorrhizal populations due to secondary colonization, which have been investigated often, are also emphasized.

Impact of Mushrooms’ Vegetative Places and Morphological Parts of a Fruiting Body on the Fatty Acids Profile of Wild Leccinum aurantiacum and Leccinum versipelle

The aim of this study was to indicate potential differences in composition of fatty acids between two mushroom species as well as to examine the impact of mushrooms’ vegetative places and morphological parts of a fruiting body on the fatty acids profile. The research material consisted of 72 samples of wild Leccinum aurantiacum and Leccinum versipelle in the form of caps and stipes, collected from three selected regions of Poland. Determination of the examined compounds was performed by gas chromatography (FID). Linoleic (C18 : 2), oleic (C18 : 1) and palmitic (C16:0) acids were the predominant compounds in all samples under study. The profile of fatty acids in Leccinum aurantiacum and Leccinum versipelle was varied depending on mushroom species, a region and morphological parts of a fruiting body. The high content of polyunsaturated fatty acids in polish L. aurantiacum and L. versipelle provides that the mushroom may be recommended in different types of diets.
