If it is like a blob of very hard jello Its snail eggs. funguses tend to look fuzzy.
Scrap it off and toss it out if you dont want them but snails are only a cosmedic nusence and will help eat any food that falls to the bottom and srape the algea away from the walls of the tank.
Get a pleco or some sort of suckermouth cat. They will keep driftwood very clean. And they will love you for giving them driftwood: to help with digestion and to provide a hiding place.
From what I've asked other people here in the forums, it seems like bogwood fungus is pretty common. If it doesn't go away in a day or two, just scrub it off.
