There is little hard things all over my garden. Accumulated on leaves sprinkled on the mulch etc. They are hard non symmetrical. Nothing seeding above. No signs of fungus or mold. No bugs. The texture/color is close to ground up nuts. My neighbors and I are stumped! Please help! I'm located on the gulf side of Florida north of Tampa (if that helps). Seemed to come over night. What could this be???
