frogspawn desease?

[salty55]

i remember reading something a few months ago about a desease that grows on frogspawn. if i remember right it was described as being white, encrusting over the top of the stalk and choking off the polyps until the coral dies.
i'm not sure if mine has this problem or if it is normal growth. but, a couple nites ago one of my turbo's knocked my frogspawn over. this made his polyps retract more than they normally do at night. thats when i noticed that there appeared to be something growing inward, over the polyps in one area. it was white like the skeleton of the coral, maybe just a little briter white than normal. does this sound like it may be a problem?

Can you get a picture?

no, his polyps don't normally retract enough to see it.
