In this study, sample 9 differed in color from the
standard found for the other samples.
On analysis, the presence of saprophytic fungi (Cladosporium
sp.) was confirmed rather than of pollen, as expected.
[The sample] presented black color and was
composed exclusively by saprophytic fungi

The reason for that is unknown,
but high ambient humidity associated with limited
supply of protein sources near the apiary may have
influenced the bees to supply the colony needs by collecting
fungi from rotten fruit.

Fungi loads presented higher contents of protein,
mineral matter and dry matter contents and lower contents
of organic matter, ethereal extract and total carbohydrate
as compared to the mean results of the nutritional
components of the pollen load.
