2010-2014年在捷克共和国的92个微地点对Bankera、Hydnellum、Phellodon和Sarcodon属的有刺水螅类真菌的多样性进行了研究。利用植物社会学的方法记录了它们的植被。共发现水螅类26种。单个微区有1-6种水螅类。某些物种对或类群频繁共现。采用多变量分析对水螅类与植被之间的群落格局进行了分析，并划分为层和植物功能类群。我们证实了植被层和功能群对水螅类个体的影响是不同的。水螅虫的发生是有条件的，特别是在优势树种上。水文样地的主要植被梯度由落叶乔木与针叶树的比例来表示。除云杉外，灌木和草本层中较小的乔木没有显著的作用。一些水合植物发生在植物层丰富的地点，而其他水合植物发生在有石楠丛和地衣的地点，被喜湿苔藓覆盖的潮湿地点，或仅被凋落物覆盖的光秃秃的土壤。概述了在演替过程中促进、系统发育的保守性和树优势的改变等可能的因素。总结了形成“水螅样地品质”的生境条件，包括捷克水螅样地最丰富的特点。(C) 2017 Elsevier Ltd和British myologicalsociety。版权所有。
The diversity of stipitate hydnoid fungi of the genera Bankera, Hydnellum, Phellodon and Sarcodon was Studied at 92 microlocalities in the Czech Republic in 2010-2014. Their vegetation was documented by means of phytosociological releves. In total, 26 hydnoid species were found. Individual microlocalities hosted 1-6 hydnoid species. Frequent co-occurrence of certain species pairs or groups was revealed. Multivariate analyses were used to test community patterns between hydnoids and vegetation, divided into layers and plant functional groups. We confirmed the hypothesis that vegetation layers and functional groups have different effects on the individual hydnoid species. The occurrence of hydnoids is conditional especially on the dominant tree species. The main vegetation gradient of hydnoid sites is represented by the proportion of deciduous versus coniferous trees. Smaller trees in shrub and herb layers do not play a significant role except for spruce. Some hydnoids occur at sites with a species-rich herb layer, whereas others occur at sites with ericoid heaths and lichens, wet sites covered with hygrophilous mosses, or bare soils only covered by litter. Possible factors favouring hydnoids and causing their accumulation at small sites are outlined, e.g. facilitation, phylogenetic conservatism and alteration of tree dominants during succession. Habitat conditions creating "hydnoid site quality" are summarized including the character of the Czech hydnoid-richest sites. (C) 2017 Elsevier Ltd and British Mycological Society.
