Not sure if it a type of fungi, but was under the pictured whatever grass type, attached to its below ground roots, along with that tiny 3mm-5mm red berry looking thing.
The plain fungi looking thing was about 2-3cm, one pic shows the inside, broken in half, & felt like a squishy mushroom.
Is it likely related to the little red berry looking thing? Is it part of that grass root? or totally separate thing just entangled in the roots?
The yellow, squishy thing is the Scleroderma. As the powdery spores mature the inside gets softer and, when mature, the outer skin splits cracks to expose the powdery mass of spores to dispersal by wind. The little red berry looking thing is something different, perhaps fungal, perhaps not. Can't tell.
