Ascospore analysis suggested that the fungus is homothallic but will preferentially outcross . 从分析子囊孢子的结果看出，此菌能同亲配合，但很易异型杂交。

Only homothallic cbs g possessed a single independent lineage . both a . mellea and a . tabescens appeared in two groups . the two clusters of a . mellea correlated to the geographical origin of the isolates , one is the north american lineage and another is the european lineage 用11个种43个图谱的数据建立了聚类树图，可以清楚地见到9个类群，只有cbsg拥有一个单独的发育系，蜜环菌狭义种和假蜜环菌都存在两个不同的发育系，蜜环菌狭义种的两个发育系与地理起源有关，一个是北美菌株发育系，另一个是欧洲菌株发育系。
