*3.1. Microscopic Examination*

A significant number of honeydew elements were detected in all honeys. The grea<sup>t</sup> majority of the samples also contained fungal spores which are present solely in pine honeys [48]. The HDE/P ratio showed a grea<sup>t</sup> variation and was on average 8.23 ± 16.98, while the total number of pollen grains in 10 g of honey was 57 871 ± 55 867 (Tables 1 and S1). In about half of the samples, the HDE/P ratio was below 3, which is the minimum value for honeydew honeys proposed in the past [49]. However, later studies have shown that the HDE/P ratio of honeydew honeys may vary and Greek pine honeys have relatively few honeydew elements and large numbers of pollen grains [39,48,50–53]. Thus, the samples were considered typical Greek pine honeys.
