为了解日本富士山火山荒漠中外生菌根真菌先驱菌根真菌紫孢菌（gilaccaria amethystinaandLaccaria laccatat）的繁殖情况，对孢子实的原位遗传动态进行了分析。分别连续3年和2年在细尺度和大尺度上取样，利用微卫星标记进行分型。在精细尺度分析中，我们发现了许多小基因，其中大多数是每年出现和消失的。螨剂的高密度和每年更新表明通过孢子有性繁殖的频繁更替。在大规模分析中，我们发现在最短距离类中存在正的空间自相关性。等位基因聚类分析也表明，几个等位基因只分布在一个小的局部区域。这些结果表明，有助于有性生殖的伞虫孢子可能只分散在离孢子囊很短的距离上，而孢子囊本身是通过罕见的长距离孢子传播建立起来的。这种罕见的远距离传播与频繁的短距离传播相结合，体现在其寄主柳蝇（Salix reinii）的种子建立模式上。
To understand the reproduction of the pioneer ectomycorrhizal fungiLaccaria amethystinaandLaccaria laccatain a volcanic desert on Mount Fuji, Japan, the in situ genet dynamics of sporocarps were analysed. Sporocarps of the twoLaccariaspecies were sampled at fine and large scales for 3 and 2 consecutive years, respectively, and were genotyped using microsatellite markers. In the fine-scale analysis, we found many small genets, the majority of which appeared and disappeared annually. The high densities and annual renewal ofLaccariagenets indicate frequent turnover by sexual reproduction via spores. In the large-scale analysis, we found positive spatial autocorrelations in the shortest distance class. An allele-clustering analysis also showed that several alleles were distributed in only a small, localised region. These results indicate thatLaccariaspores contributing to sexual reproduction may be dispersed only short distances from sporocarps that would have themselves been established via rare, long-distance spore dispersal. This combination of rare, long-distance and frequent, short-distanceLaccariaspore dispersal is reflected in the establishment pattern of seeds of their host,Salix reinii.
