its sounds like fungi ,birds nest fungi have a look and let me know what you think.



Bird's nest fungi (Mycocalia, Nidularia, Nidula, Cyathus, and Crucibulum spp.), sphere throwers (Sphaerobolus spp.), and shotgun fungi (Pilobolus spp.) are three separate groups of fungi with many similarities.

Bird's nest fungi, sphere throwers, and shotgun fungi are all saprophytes, which grow on manure or decaying wood. Since these fungi live only on decaying plant matter, they do not harm living plants. In the garden, the tiny (under 1/4 inch tall) fungi are usually found on the surface of soil, which has been enriched with manure, sawdust, or wood chips. They can also be found on old boards used to edge garden beds and on wooden plant labels and stakes. The fungi are usually spread in manure, however, some species may occur as contaminants within seed mixes.

All of these fungi can forcibly eject their spores in hard egg-like structures called peridioles. These structures can be ejected one yard or more. The sticky spore cases adhere to plant foliage and other surfaces, including home siding and patio furniture.

These fungi are rarely noticed unless they are brought indoors on container-grown plants. The first sign is shiny black or dark brown objects resembling seeds or insects on the leaves. These are the egg-like structures that have been ejected by the fungi. If unsightly, they can be picked off the leaves. To help control these fungi, remove any fungal fruiting bodies from the surface of the soil. Repotting the plant in a potting medium that does not contain manure or wood should prevent the fungi from returning
