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.
