Durio zibethinus Durio zibethinus Durio zibethinus is the most common tree species in the genus "Durio" that are known as durian and have edible fruit also known as durian. As with other durian species, the edible flesh emits a distinctive odour that is strong and penetrating even when the husk is intact. Some people regard the durian as having a pleasantly sweet fragrance; others find the aroma overpowering and revolting. The smell evokes reactions from deep appreciation to intense disgust, and has been described variously as rotten onions, turpentine, and raw sewage.

Suillus sibiricus Its odour is not distinctive. In North America, "Suillus americanus" has a similar appearance, but a more easterly distribution. It is associated with eastern white pine. Although some authors have tried to distinguish between the two with by using width of the stem, or by differences in fruit body colouration, it is acknowledged that these characteristics are variable, and depend on environmental factors. The phylogenetic analysis of Wu and colleagues (2000) suggests that the two taxa may be the same, although more samples from different geographical areas will be needed to verify this. "Suillus sibiricus" has been recorded in parts
