摘要Purple Laccaria are ectomycorrhizalbasidiomycetes associated with temperate forests all over the Northern Hemisphere in at least two taxa: Laccaria amethysteo-occidentalis in North America, and L. amethystina complex in Eurasia, as shown by Vincenot et al. (2012). Here, we combine a further study of the genetic structure of L. amethystina populations from Europe to southwestern China and Japan, using neutral Single Sequence Repeat (SSR; microsatellite) markers; and a systematic description of two novel Asian species, namely Laccaria moshuijun and Laccaria japonica, based on ecological, morphological, and molecular criteria (rDNA sequences). Population genetics provides evidence of the ancient isolation of three regional groups, with strong signal for speciation, and suggests a centre of origin of modern populations closest to present-day Chinese populations. Phylogenetic analyses confirm speciation at the molecular level, reflected in morphological features: L. moshuijun samples (from Yunnan, China) display strongly variable cheilocystidia, while L. japonica samples (from Japan) present distinctive globose to subglobose spores and clavate cheilocystidia. This study of a species complex primarily described with an extremely wide ecological and geographical range sheds new light on the biodiversity and biogeography of ectomycorrhizal fungi.
