Overall Overview

Total pollen decreased from 68 to 38 (−30).
Total mold spores increased from 11,082 to 16,085 (+5,003).

Pollen declined sharply across all categories, while mold rose materially.


Tree, Grass, and Weed Pollen

Tree Pollen (16 → 4, −12)

Main contributors:

  • Carya (Hickory/Pecan): −4 (6 → 2)
  • Pinaceae (Pine): −4 (6 → 2)
  • Other Tree: −4 (4 → 0)

Tree pollen contracted significantly, with all contributing categories declining.


Grass Pollen (20 → 12, −8)

Grass levels fell meaningfully but remain present.


Weed Pollen (32 → 22, −10)

Largest decreases:

  • Plantago (Plantain): −12 (18 → 6)
  • Artemisia (Sage): −4 (6 → 2)
  • Cyperaceae (Sedge): −2 (2 → 0)

Offsetting increases:

  • Rumex (Sheep Sorel): +4 (2 → 6)
  • Other Weed: +4 (2 → 6)

Weed totals declined overall, led by the drop in plantain.


Mold Spores (11,082 → 16,085, +5,003)

Largest Absolute Increases

  • Ascomycetes: +3,323 (7,460 → 10,783)
  • Basidiomycetes: +1,671 (1,050 → 2,721)
  • Penicillium/Aspergillus: +49 (230 → 279)
  • Epicoccum: +18 (18 → 36)
  • Dreshslera/Helminthosporium: +8 (14 → 22)
  • Periconia: +8 (6 → 14)
  • Algae: +8 (0 → 8)

Largest Decreases

  • Smuts/Myxomycete: −52 (137 → 85)
  • Cercospora: −26 (48 → 22)
  • Curvularia: −14 (20 → 6)

The mold increase was driven overwhelmingly by large gains in Ascomycetes and Basidiomycetes, which more than offset declines in several smaller categories.


Key Takeaways

  • Pollen dropped sharply across tree, grass, and weed categories, cutting total levels nearly in half.
  • Tree pollen is now minimal, with only small residual hickory/pecan and pine counts.
  • Weed pollen declined primarily due to a reduction in plantain.
  • Mold spores rose substantially, driven primarily by strong increases in Ascomycetes and Basidiomycetes.
  • Overall pattern: lower pollen burden but significantly higher mold exposure compared to the prior day.
