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）真菌物种的知识积累、分布测绘与文献建档作出贡献，并对格塞奥国家公园（Gesäuse National Park）的真菌生物多样性开展评估，尤其聚焦该保护区未来的真菌学研究目标。研究依据最具潜力的生境条件，选定了6个样地（接待区域）。除本次新采集的样本外，同时评估了格拉茨大学植物科学研究所（Institute of Plant Sciences of the University of Graz, GZU）的馆藏标本资料。 本次调查最终记录到169种真菌，研究对其中部分发现进行了简要评述。其中，圆筒孢座壳（Camarops tubulina）极有可能为施蒂利亚州真菌区系的新记录种。根据约阿内姆州立博物馆（Joanneum State Museum）植物学部本土真菌工作组（Heimische Pilze）的卡片档案数据，本次名录中列出的部分物种已在施蒂利亚州绝迹，例如齿韧革菌（Mycoacia uda）、腐生阿太菌（Athelia decipiens）、硫黄双盘菌（Bisporella sulfurina）。在溪床浮木上，发现了若干极具科研价值的小果生子囊菌记录，其中包含H.韦格林（H. Wegelin）于1894年描述、后续极少被提及的3个类群（科）：瑞士双壳孢（Amphisphaeria helvetica，本次鉴定为Otthia h.）、瑞士拟茎点霉（Phomatospora helvetica，本次鉴定为Ph. moravica）以及长孢斯特里凯菌（Strickeria longispora）。仅有1个物种——柔毛栓菌（Trametes pubescens）被《奥地利红色名录》列为濒危（等级3）。本文还简要探讨了依据国际自然保护联盟（International Union for Conservation of Nature, IUCN）分类标准，对木材栖生真菌的风险等级进行合理分级的难点。
