I have some of them as well. They will also get larger as well.
gbose said:I've got them too. Do they develop any color, or always stay white?
I have some that are bout 1" in diameter. It just appeared one day or I noticed it and I have been watching it grow from there. Can't say how big before it stops growing but I have seen grwth over the last 6 months. It started about 1/4th the size.how large? the bigger one in my pic is the size of a dime
