In contrast, there were three kinds of flyspeck: black dot, brown dot and micro-dot. 其中的雪花状、条块状、微点类和棕点类为新的类型。

These results showed that the kinds of the pathogens of apple sooty blotch and flyspeck were of high diversity, probadly including some special types. 以上结果显示，我国苹果煤污病和蝇粪病病原菌菌体类型具有丰富的多样性，其中可能包括一些特殊的类型。

The samples of apple sooty blotch and flyspeck were collected from different apple growing places in Shaanxi province, China. 摘要苹果煤污病和蝇粪病症状复杂多样，症状类型是研究其病原多样性的基础。

Pathogen diversity analysis of Sooty blotch and flyspeck (SBFS) by the internal transcriber spacer (ITS) and larger subunit (LSU) sequences. 利用核糖体内部转录间隔区（ITS）和大亚基（LSU）核苷酸序列对苹果煤污病与蝇粪病病原进行多样性分析。
