since it was already in a tank there is a 100% chance of fungus.. i have never not had a piece fungus up a bit after being in a tank and then left to dry then put in a tank again..
however fungus is white, fuzzy and easy to rub off..
if you need a wire brush to get the stuff off my guess is that its some strand of fresh water barnacle... as to what kind i have no idea.. other than knowing that they exist i dont know much else about them..
