Mushrooms dead

[grrrrhh]

got a big rock last night full of these mushrooms. after waking up this morning, saw that every single one of them are covered with brown slime and almost all of them has desintegrated. can brown jelly kill mushroom this fast? this is the first time i have experienced an overnight death of a coral.
