The studies on distributional changing of popular lichen Lecanora muralis and germination of lichens

正如Seward(1976)指出的那样，这种世界性物种在地理上无处不在，在生态上多样，在分类上也是多态的。许多种下的种被证明，但有许多中间形式。它的底物是可变的。本种最经常在岩石上生长，但很少在苔藓和倒下的树干上生长。在研究Lecanora subfusca群(宫城1988)期间，我记录了从北海道到本州岛生长Lecanora Muraris的24个点。1978年至1983年，我自己调查了11个点，但我只收集了和佐町和1945年原子弹爆炸后的前广岛大学校区两个地方的Lecanora Muraris。在前广岛大学大楼里，只在街区之间的水泥部分发现了莱卡诺拉·穆拉里斯。我以为日本岛被来自东部大陆的酸雨污染了。发芽试验还需要进一步的研究才能澄清这一假说。用Caladistic方法研究了发芽规律，包括发芽方式、发芽方式等。Takeshita等人(1998)报告说，在第一次分枝之前，Lecanora物种的萌发数量为1-2个。但我们发现了3-5个新的萌发。通过聚类分析，最接近的种类是粉状乳杆菌。

This cosmopolitan species is, as pointed out by Seaward (1976), geographically ubiquitous, ecologically versatile and taxonomically polymorphic. Many infraspecific species are demonstrated, but there are many intermediate forms. Its substrate are variable. This species grows most frequently on rocks, but rarely on moss and fallen tree-trunks. During the study of Lecanora subfusca group (Miyawaki 1988); I recorded 24 points where Lecanora muralis are growing from Hokkaido Island to Honshu Island. from 1978-1983.Eleven points were investigated by myself, but I collected Lecanora muralis only two localities Wakasa-cho and former Hiroshima University Campus which building was suffered by the atomic bomb in 1945. In former Hiroshima University building, Lecanora muralis was found on only cement part between the block. I considered Japan Island were polluted by the acidy rain from the east continent. Further study of about the germination test must be needed for clarify this hypotheses.Including germination pattern, the relationship between Lecanora muralis, L. niponica, L. pulverulenta L. subimmergens L. imshaugu were studied by using caladistic method. Takeshita et al (1998) reported that before the first branching the germination number was 1-2 in the Lecanora species. But we found 3-5 new germination. By using caladistic method, the nearest species of Lecanora muralis was L. pulverulenta among those species.
