Taiwan is geographically special in that it lies in an evolutionary transition zone between southern and northern hemisphere fungi, so that many local varieties and hybrids appear here. For example, the Taiwanese pine mushroom is a local variety, somewhat different from mushrooms of the same species in other regions.
由於台灣的地理位置特殊，正位於南半球菌類演化為北半球菌類的過渡地帶，因此常有變種或新組合種的出現，像松茸就是台灣的變種菇類。
