White globular parasite growing on gills of Gymnopilus.

When I put the coverslip down the white mass exploded into the water. Very fragile.

The spores inside were tiny, hyaline, and of various shape. Photos attached.

I thought it was insect related but it does seem to be spores.

After big rains these spores appeared on a termite mound, the termites did not move or interact with the spores. Is it’s a type of Termitomyces or Fibulorhizoctonia (cuckoo fungus) species? The fungi appear a few days later

Found in a potted Crassula ovata plant.
Pileus surface grabrous.
Lamellae unchanging when bruised.
Spores dextrinoid, (5.3–)5.5–6.3(–6.6) × (3.6–)4–4.6(–4.5) μm, (mean length = 5.87 ± 0.4, mean width = 4.29 ± 0.28, Q = (1.2–)1.3–1.5(–1.6), mean Q = 1.38 ± 0.14).
Basidia 4-spores, (18.4–)19.2–22.6(–22.3) × (7.2–)7.3–8.5(–8.7) μm, (mean length = 20.91 ± 1.74, mean width = 7.92 ± 0.62, Q = (2.1–)2.3–3.1(–3), mean Q = 2.66 ± 0.4).
Pleurocystidia were not observed.

Compared to L. birnbaumii, spores are much smaller, Pileus is glabrous, and color is pale.

Tiny, by anyone's standards. Not easily observed except via enlarged photography. Occurring on Cow Dung that is about (no less than) 8 weeks old.
They are little more that 6-10mm high when mature. They quickly deliquesce once the cap is open. Delicate, silvery stipe with grey, slightly warty, cap
,
It is possible they might be Coprinopsis xenobia

But further microscopic ID by me is impossible. These occur in the sheltered folds of the dung, in partnership with much larger Cheilymenia and the really tiny Pilobolus, each seen in the photos.
