北海道において,植栽されたナルコユリ(アマドコロ属)の根茎から発生した子嚢果について形態学的な検討を行った結果,Stromatinia rapulumと同定した.本種はヨーロッパではアマドコロ属を宿主とするが,日本では従来ツルドクダミが宿主とされ,日本産標本の菌と宿主の種同定には疑問の余地があった.本報告は,S. rapulumの日本で初めての確かな採集記録であり,新たにナルコユリチャワンタケという和名を提唱した.

Not a small amount is spent on the brake shoes in the expenditures of railway maintenance. And great efforts have been made to cut down this expense.   As a result of adapting High Phosphorus Cast Iron Brake Shoes, Kinki Nippon Railway Company has succeeded in cutting down much of the cost, by prolonging its life more than 45% in the year 1959 as compared with that of 1951. This reprot shows the following two points which prove the superiority of High Phosphorus Brake Shoes.   These results were obtained both by actual car tests and by laboratorial test. 1. It is possible to say that High Phosporus Cast Iron Brake Shoes of Kinki Nippon Railway Co. specification of about H.B.250 wear almost 20% less than most widely used Low Phosphorus Brake Shoes of about H.B.220. 2. When the effect on the wear of tire wheels is considered, it is also possible to say that when Low Phosphorus Cast Iron Brake Shoes are used, the degree of wear runs parallel with the hardness of the material. But when High Phosphorus Cast Iron Brake Shoes are used no tendency as mentioned above can be found, and it is also made clear that the use of High Phosphorus Cast Iron Brake Shoes is good for both wheels and Brake Shoes.
