Overall Overview

Total pollen was unchanged, holding steady at 2, with no net movement across pollen categories. Total mold increased by 666, driven by gains in a few large mold groups that more than offset declines elsewhere.

Tree, Grass, and Weed Pollen

  • Tree pollen was flat overall, with Cedar up by 2 offsetting Elm down by 2.
  • Grass pollen remained at zero.
  • Weed pollen remained at zero across all species.

Mold Spores

  • The increase was led by a large rise in Ascomycetes (+699), the single biggest contributor to the day-over-day change.
  • Basidiomycetes (+104) also added meaningfully to the total.
  • Smaller increases were seen in Smuts/Myxomycete (+6) and a few minor species.
  • Offsetting these gains were declines in Cladosporium (-115) and Algae (-18), along with smaller pullbacks across several low-volume categories.

Key Takeaways

  • Pollen levels were stable, with only minor internal shifts among tree species.
  • Mold levels moved higher, driven primarily by a rebound in Ascomycetes.
  • Declines in Cladosporium and Algae reduced, but did not reverse, the overall mold increase.
