Overall Overview
Total pollen increased by 40, rising from 76 to 116. The gain was driven primarily by a sharp rise in tree pollen (+36).
Total mold increased by 1,901, led by large increases in Cladosporium and Basidiomycetes, partially offset by a decline in Ascomycetes.
Tree, Grass, and Weed Pollen
Tree pollen increased by 36, driven mainly by:
- Carya (Hickory/Pecan) +46
- Quercus (Oak) +6
Offsetting declines included:
- Fraxinus (Ash) −8
- Pinaceae (Pine) −8
Grass pollen increased by 2.
Weed pollen rose by 2, with:
- Other Weed +4
- Cyperaceae (Sedge) +2
- Plantago (Plantain) −4
Mold Spores
Total mold increased by 1,901.
Largest increases:
- Cladosporium +2,130
- Basidiomycetes +535
- Smuts/Myxomycete +172
- Alternaria +114
- Penicillium/Aspergillus +72
- Epicoccum +60
- Dreshslera/Helminthosporium +36
- Cercospora +33
Largest decrease:
- Ascomycetes −1,255
Additional smaller declines occurred in Curvularia, Oidium/Erysiphe, Pithomyces, Spegazinia, and Torula.
Key Takeaways
- Tree pollen was the primary driver of higher total pollen, led by Hickory/Pecan.
- Grass and weeds showed minor increases relative to trees.
- Mold levels rose materially, with Cladosporium accounting for most of the increase.
- The decline in Ascomycetes partially offset broader mold gains.
