Overall Overview
Total pollen increased from 72 to 96 (+24).
Total mold spores increased from 6,339 to 13,494 (+7,155).
The dominant shift day over day was the substantial rise in mold levels.
Tree, Grass, and Weed Pollen
Tree Pollen (24 → 40, +16)
Primary contributors:
- Carya (Hickory/Pecan): +8 (4 → 12)
- Juglans (Walnut): +6 (2 → 8)
- Other Tree: +4 (6 → 10)
- Pinaceae (Pine): −2 (6 → 4)
- Quercus (Oak): no change (6 → 6)
Tree increases were concentrated in hickory/pecan and walnut.
Grass Pollen (12 → 4, −8)
Grass pollen declined materially. No individual grass species breakdown was provided, but the category total fell by 8.
Weed Pollen (36 → 52, +16)
Largest contributors:
- Plantago (Plantain): +8 (16 → 24)
- Urticaceae (Nettle): +8 (0 → 8)
- Rumex (Sheep Sorel): +2 (2 → 4)
- Typha (Cattail): +2 (0 → 2)
- Artemisia (Sage): −2 (2 → 0)
- Chenopodiaceae/Amaranthaceae (Amaranth): −2 (4 → 2)
Weed gains were driven primarily by plantain and nettle.
Mold Spores (6,339 → 13,494, +7,155)
The increase was broad-based, with several large contributors:
Major Absolute Increases
- Ascomycetes: +3,141 (3,699 → 6,840)
- Cladosporium: +2,236 (868 → 3,104)
- Basidiomycetes: +1,482 (1,634 → 3,116)
- Smuts/Myxomycete: +87 (22 → 109)
- Penicillium/Aspergillus: +85 (0 → 85)
- Alternaria: +40 (26 → 66)
- Cercospora: +40 (12 → 52)
Notable Decreases
- Oidium/Erysiphe (Powdery Mildew): −6 (14 → 8)
- Periconia: −4 (6 → 2)
- Torula: −4 (4 → 0)
The mold surge was primarily attributable to Ascomycetes, Cladosporium, and Basidiomycetes.
Key Takeaways
- Overall pollen rose modestly, driven by tree and weed increases, despite a drop in grass pollen.
- Tree gains were concentrated in hickory/pecan and walnut.
- Weed growth was led by plantain and nettle.
- Mold levels more than doubled, with Ascomycetes and Cladosporium accounting for the largest absolute increases.
- The day-over-day change was dominated by mold expansion rather than pollen movement.
