Comparison of typical optical microscopy photographs of HV filter samples (left: collected during the rainy period of September 2 to October 5, 2016, total volume of 9,094 m3; right: collected during the nonrainy period of September 5 to September 6, 2016, total volume of 1,296 m3). Samples from the rainy period display many coarse club- and oval-shaped particles, with some hypha-like materials. These are considered macroconidia. A portion of the particles exhibit sizes greater than 20 μm (red bar). On the other hand, the sample from the fine period displays many small dot-like particles of a few μm or smaller in size. Note that no size cut-off was applied during the sampling. The total pixel size of the photograph was originally 2,728 × 2,198 = 5,996,144.
