Mycorrhiza. 2016 Apr;26(3):215-25. doi: 10.1007/s00572-015-0662-3. Epub 2015 Sep 24.
Ectomycorrhizas (ECM) of Inocybe species (Inocybaceae, Basidiomycota) formed by three host plant species (Populus alba, Salix rosmarinifolia and Pinus nigra) in a semiarid woody steppe of Hungary were studied. To identify the fungal partners, we performed phylogenetic analyses of nucleotide sequences for the internal transcribed spacer region of nuclear DNA (nrDNA ITS) together with sequences gained from public databases. Seven Inocybe ectomycorrhiza morphotypes were morpho-anatomically characterised. Five morphotypes were identified (I. phaeoleuca, I. psammophila, I. semifulva, I. splendens and I. subporospora), whereas two morphotypes represented unidentified Inocybe species. Differences were discernible among the morphotypes, and they showed general anatomical characteristics of Inocybe ECM, such as the slightly organised plectenchymatic mantle (types A, B and E and the gelatinous C). The ECM of I. subporospora and I. phaeoleuca were detected from the introduced Pinus nigra. These two fungi are probably native to the area but capable of forming a novel ectomycorrhizal association with the invasive host.
对匈牙利半干旱木本草原中由三种寄主植物（银白杨、迷迭香柳和黑松）形成的丝盖伞属（丝盖伞科，担子菌门）外生菌根进行了研究。为了鉴定真菌伙伴，我们对核DNA的内部转录间隔区（nrDNA ITS）的核苷酸序列以及从公共数据库获得的序列进行了系统发育分析。对七种丝盖伞外生菌根形态型进行了形态解剖学特征描述。鉴定出了五种形态型（暗褐丝盖伞、沙生丝盖伞、半黄丝盖伞、华丽丝盖伞和近孔丝盖伞），而两种形态型代表未鉴定的丝盖伞物种。不同形态型之间存在明显差异，它们表现出丝盖伞外生菌根的一般解剖特征，如组织略显松散的拟薄壁组织菌套（A、B和E型以及凝胶状的C型）。从引入的黑松中检测到了近孔丝盖伞和暗褐丝盖伞的外生菌根。这两种真菌可能原产于该地区，但能够与入侵寄主形成新的外生菌根共生关系。
