Abstract

The review is devoted to the taxonomic representation of the order Cantharellales in connection with problems of taxonomical history of the group and problems of its ecological diversification. The history of the taxonomy of Cantharellales is considered, and it is shown that at present the order is limited to no more than 550 species from 31 genera and 5 families: Aphelariaceae (Aphelaria, Phaeoaphelaria, Tumidapexus); Botryobasidiaceae (Botryobasidium with anamorphs, Suillosporium); Ceratobasidiaceae (Ceratoporia, Ceratobasidium pr.p., Rhizoctonia); Hydnaceae (Bergerella, Bryoclavula, Bulbilla, Burgella, Burgellopsis, Burgoa, Cantharellus, Clavulina, Craterellus, Gloeomucro, Hydnum, Ingoldiella, Membranomyces, Minimedusa, Multiclavula, Neoburgoa, Parastereopsis, Repetobasidiellum, Rogersiomyces, Sistotrema, Sistotremella); and Tulasnellaceae (Pseudotulasnella, Stilbotulasnella, Tulasnella). The unresolved problems of the Cantharellales taxonomy are discussed. The ecomorphological and ecological-trophic diversification of the order is consi-dered. A synopsis of families and genera is given with identification keys and detailed original taxa diagnoses down to the generic level. It is concluded that, during the evolution of the order Cantharellales and other large groups of Agaricomycetes, there is a parallelism associated with the development by fungi of similar adaptive zones that opened up in connection with the Early Cretaceous diversification of the terrestrial biota: the co-lonization of wood debris with the formation of hypochnoid, corticioid, and secondary resupinate forms; fo-rest litter with the formation of clavarioid and ramarioid forms; the development of sporulation within grasses with a reduction of cantharelloid and secondary formation of clavarioid forms; the formation of ectomycorrhizae and orchid mycorrhiza by lignotrophic fungi; and colonization of moss protonemata, films of aerophytic algae, and lichen thalli.

Cantharellales 目：分类和生态多样性

摘要本综述结合坎塔雷尔目分类学历史问题及其生态多样化问题，专门论述了坎塔雷尔目在分类学上的代表性。文章回顾了坎塔雷尔目分类学的历史，并指出目前坎塔雷尔目只有 5 科 31 属不超过 550 个物种：Aphelariaceae（Aphelaria，Phaeoaphelaria，Tumidapexus）；Botryobasidiaceae（Botryobasidium with anamorphs，Suillosporium）；Ceratobasidiaceae（Ceratoporia，Ceratobasidium pr.p、Rhizoctonia）；水螅科（Bergerella、Bryoclavula、Bulbilla、Burgella、Burgellopsis、Burgoa、Cantharellus、Clavulina、Craterellus、Gloeomucro、Hydnum、Ingoldiella、Membranomyces、Minimedusa、Multiclavula、Neoburgoa、Parastereopsis、Repetobasidiellum、Rogersiomyces、Sistotrema、Sistotremella）；以及土拉菌科（Pseudotulasnella、Stilbotulasnella、Tulasnella）。讨论了 Cantharellales 分类学中尚未解决的问题。对该目在形态学和生态营养学上的多样化进行了梳理。给出了科和属的概述，并附有识别钥匙和详细的原始分类群诊断，直至属级。结论是，在姬松茸目和其他大型姬松茸类群的进化过程中，与真菌在早白垩世陆地生物群多样化过程中开辟的类似适应区的发展有平行关系：木屑的共同隆起，形成了下瘤胃、皮质瘤胃和次生瘤胃；枯枝落叶的共同隆起，形成了克拉瓦里奥瘤胃和拉马里奥瘤胃；禾本科植物内孢子的发展，形成了茎状孢子和次生茎状孢子；木质营养真菌形成了外生菌根和兰花菌根；苔藓原生质、气生藻膜和地衣苔藓的定殖。
