unidentified fungi

Description:

Dozens of small (~ 3 mm diameter, the size of a BB) white spherical fungi growing from a fallen log, with stalks ~ 5 mm long and < 1 mm thick (first picture) and to their left (second picture) many similarly-sized white fungi, many of which were spear- or closed umbrella-shaped.

Habitat:

Mixed native and alien tropical insular montane forest.

Notes:

Spotted along Likeke Trail below the Nuuanu Pali lookout on Oahu. There was no opportunity to take measurements or collect specimens. The camera flash unfortunately bleached out whatever otherwise observable tonal variation there might have been in the whiteness of the balls. However it did not appear that the balls were unopened mushroom caps.
