Overall Overview

Total pollen increased by 22, driven entirely by higher tree pollen. Total mold declined by 114, as a large drop in one dominant mold category outweighed several smaller increases.

Tree, Grass, and Weed Pollen

  • Tree pollen rose by 22, led by Cedar (+20) and Elm (+4).
  • Other Tree pollen declined by 2, partially offsetting the increase.
  • Grass pollen remained at zero.
  • Weed pollen remained at zero across all species.

Mold Spores

  • The largest decline came from Ascomycetes (-425), which drove most of the reduction in total mold.
  • Significant increases were seen in Smuts/Myxomycete (+172) and Cladosporium (+65).
  • Additional smaller gains occurred in Epicoccum (+18), Alternaria (+10), Curvularia (+8), and several low-volume species.
  • Offsetting these increases were declines in Penicillium/Aspergillus (-6) and Nigrospora (-2).

Key Takeaways

  • Tree pollen rebounded sharply, almost entirely due to Cedar.
  • Weed and grass pollen remained inactive.
  • Mold totals fell overall, despite several notable increases, because the Ascomycetes decline dominated the day’s changes.
