Physarum cinereum

Bruce Ing says it fruits on grass and the plasmodium often becomes bright yellow prior to fruiting, during which the young sporocarps are shinning lilac-purple.

Does not look right for Leocarpus fragilis wrong shape, size and even colour does not seam right . I would have exspected more yellow then orange. I suspect they are to immature to name at this stage.

They are too small for Leocarpus. I suspect Arcyria, but need to see a sporocarp.
