自1950年以来，在荷兰的海绵状真菌孢子果的频率变化进行了分析，使用几种方法。所有22个本地物种显示，从1950年起显着减少。与水青冈属和栎属的12个物种的部分恢复，自1998年以来证明。与松属植物共生的10种植物中，有9种已经灭绝，至今没有恢复。所有物种的保护状况的变化进行了描述。讨论了频率变化的原因，认为主要与沉积氮量有关。解释了针叶树和落叶树共生体的不同反应。本文将荷兰与比利时、德国和瑞典的情况进行了比较。(C)2009 Elsevier Ltd和英国真菌学会。All rights reserved.
Changes in frequency of sporocarps of hydnoid fungi in The Netherlands since 1950 are analysed using several methods. All 22 native species show a significant decrease from 1950 onwards. For 12 species associated with Fagus and Quercus a partial recovery since 1998 is demonstrated. Among 10 species associated with Pinus nine have become extinct and no recovery is observed so far. Changes in conservation status of all species are described. The causes of changing frequencies are discussed, being mainly related to amounts of deposited nitrogen. The different reactions of symbionts of deciduous and coniferous trees are explained. The status of hydnoid fungi in The Netherlands is compared with the situation in Belgium, Germany and Sweden.
