Wood-inhabiting mushrooms from the Hartelsgraben (National Park Gesäuse, Styria, Austria)

The aim of this thesis was to contribute to the knowledge, mapping and documentation of the fungi species of Styria as well as the assessment of the biodiversity of fungi in the Gesäuse National Park, especially with regard to future objectives for the mycological research of this protected area. The six sites (reception areas) were selected according to the most promising habitat conditions. In addition to these new samples, herbaric evidence from the collection of the Institute of Plant Sciences of the University of Graz (GZU) was evaluated. In the investigation area 169 fungal species were finally detected. Some of these findings are briefly commented on. Camarops tubulina is most likely a new finding for the fungal flora of Styria. According to the records of the working group Heimische Pilze (carding data at the Department of Botany at the Joanneum State Museum), some of the species listed here were already lost in Styria (e.g. Mycoacia uda, Athelia decipiens, Bisporella sulfurina). On driftwood in the creek bed some very remarkable finds of small-fruited ascomycetes, including three families described by H. Wegelin in 1894 and hardly mentioned later: Amphisphaeria helvetica (here as Otthia h.), Phomatospora helvetica (here as Ph. moravica) and Strickeria longispora. Only one species (Trametes pubescens) is considered endangered by the Austrian Red List (category 3). The problem of realistic classification of the risk level of wood-inhabiting fungi according to IUCN categories is briefly discussed.本学位论文旨在为施蒂利亚州（Styria）真菌物种的知识梳理、分布制图与文献建档贡献力量，同时对格塞尔高夫国家公园（Gesäuse National Park）的真菌生物多样性进行评估，尤其围绕该保护区真菌学研究的未来目标开展相关工作。本次研究依据最具潜力的生境条件，遴选了六个样地（含接待区域）。除本次采集的新样本外，研究还对格拉茨大学（University of Graz）植物科学研究所馆藏标本（GZU）的资料进行了评估。 本次调查共检出真菌169种，文中将对其中部分发现进行简要评述。筒状驼孢壳（Camarops tubulina）极有可能为施蒂利亚州真菌区系的新记录种。根据本土真菌工作组（Heimische Pilze）及约阿内姆州立博物馆植物学部的编目资料，本文收录的部分物种已在施蒂利亚州区域性灭绝，例如蓝边齿毛菌（Mycoacia uda）、欺骗蜡革菌（Athelia decipiens）以及硫黄双囊盘菌（Bisporella sulfurina）。在溪床浮木上，本次研究发现了若干极具科研价值的小果实体子囊菌，其中包含H·韦格林（H. Wegelin）于1894年描述、后续几乎未被提及的三个类群：瑞士双球壳（Amphisphaeria helvetica，本次研究中以Otthia h. 指代）、瑞士拟茎点霉（Phomatospora helvetica，本次研究中以Ph. moravica 指代）以及长孢斯特里壳（Strickeria longispora）。仅毛栓菌（Trametes pubescens）被《奥地利红色名录》列为濒危物种（等级3）。本文还简要探讨了依据国际自然保护联盟（IUCN）标准对木生真菌开展风险等级客观定级所面临的现实问题。
