Abstract

Marasmius haematocephalus forms a distinctive pan-tropical species complex. While it has been confirmed that M. haematocephalus s. s. occurs only in the neotropics, morphologically similar taxa across the world continue to be attributed to this species. Phylogenies utilising nrITS, nrLSU and TEF1, were constructed to identify relationships within the complex, and morphological data used to document and explore the taxa endemic to Australia and those which co-occur in Asia, Madagascar and the USA. Seven new species found in Australia are described and illustrated - M. campaniformis sp. nov., M. pervagatus sp. nov., M. porphyrocephalus sp. nov., M. purpureospadiceus sp. nov., M. vinaceus sp. nov., M. wianwian sp. nov. and M. wunga sp. nov. A key to Australian species of the M. haematocephalus complex is provided. Historic records and observational data (iNaturalist and Atlas of Living Australia) were used to indicate potential distributions of all species within the complex that occur in Australia and explore biogeographic relationships more broadly.

紫色风车和更多：澳大利亚的Marasmius haematocephalus复合体（Marasmiaceae）。

红头Marasmius haematcephalus形成了一个独特的泛热带物种复合体。虽然已证实血头棘猴仅存在于新热带地区，但世界各地形态相似的分类群仍被认为属于该物种。利用nrITS、nrLSU和TEF1构建系统发育系统，以确定该复合体内部的关系，并利用形态学数据记录和探索澳大利亚特有的分类群以及亚洲、马达加斯加和美国的共同分布的分类群。描述并说明了在澳大利亚发现的7个新种：M. campaniformis sp. nov、M. pervagatus sp. nov、M. porphyrocphalus sp. nov、M. purpureospadiceus sp. nov、M. vinaceus sp. nov、M. wianwian sp. nov和M. wunga sp. nov。历史记录和观测数据（iNaturalist和Atlas of Living Australia）被用来表明澳大利亚所有物种在复杂区域内的潜在分布，并更广泛地探索生物地理关系。引用本文：Guard FE， Dearnaley J, Lebel T（2025）。紫色风车和更多：澳大利亚的Marasmius haematocephalus复合体（Marasmiaceae）。真菌分类与进化[j]；doi: 10.3114 / fuse.2025.16.16。
