With all the wind, the pollen has been blowing off the puffball trees (aka mesquites) and collecting against curbs and around bushes in dirty gold mounds.
Technically, it’s pollen, not spores, but the allergies brought on by this particular pollen puts me in mind of the scene in the Secret Garden where Colin works himself into a fit over the spores in the spring air. Sometimes I wouldn’t mind doing he same.
