Overall Overview
Total pollen decreased from 96 to 88 (−8).
Total mold spores decreased from 17,609 to 13,459 (−4,150).
Pollen eased slightly, while mold declined sharply from the prior elevated level.
Tree, Grass, and Weed Pollen
Tree Pollen (14 → 0, −14)
Tree pollen dropped to zero.
Main contributors:
- Carya (Hickory/Pecan): −12 (12 → 0)
- Other Tree: −2 (2 → 0)
Grass Pollen (10 → 26, +16)
Grass increased significantly and was the primary offset to the tree decline.
Weed Pollen (72 → 62, −10)
Largest changes:
- Artemisia (Sage): −12 (26 → 14)
- Other Weed: −6 (18 → 12)
- Plantago (Plantain): −2 (10 → 8)
- Rumex (Sheep Sorel): +4 (10 → 14)
- Typha (Cattail): +2 (4 → 6)
- Cyperaceae (Sedge): +2 (2 → 4)
- Chenopodiaceae/Amaranthaceae: +2 (0 → 2)
Weeds moderated but remain elevated overall.
Mold Spores (17,609 → 13,459, −4,150)
Largest Absolute Decreases
- Ascomycetes: −2,042 (9,562 → 7,520)
- Cladosporium: −1,695 (4,945 → 3,250)
- Basidiomycetes: −292 (2,278 → 1,986)
- Alternaria: −73 (206 → 133)
- Penicillium/Aspergillus: −48 (226 → 178)
- Epicoccum: −18 (68 → 50)
- Periconia: −12 (26 → 14)
- Stemphyllium: −12 (12 → 0)
Notable Increases
- Rust: +14 (12 → 26)
- Pithomyces: +10 (0 → 10)
- Algae: +8 (14 → 22)
- Curvularia: +8 (8 → 16)
The mold decline was driven primarily by large reductions in Ascomycetes and Cladosporium, which more than offset smaller increases in secondary species.
Table of Absolute Changes
| Category | Species | Change |
|---|---|---|
| Tree | Carya (Hickory/Pecan) | −12 |
| Tree | Other Tree | −2 |
| Weed | Artemisia (Sage) | −12 |
| Weed | Other Weed | −6 |
| Weed | Rumex (Sheep Sorel) | +4 |
| Mold | Ascomycetes | −2,042 |
| Mold | Cladosporium | −1,695 |
| Mold | Basidiomycetes | −292 |
| Mold | Rust | +14 |
| Mold | Pithomyces | +10 |
Key Takeaways
- Overall pollen dipped slightly despite a strong grass increase, due to tree pollen falling to zero and weeds easing.
- Grass became the dominant pollen contributor for the day.
- Mold levels dropped materially, led by sharp declines in Ascomycetes and Cladosporium.
- Combined exposure shifted to moderate pollen with lower—but still substantial—mold levels compared to the prior day.
