Having hard time to collect them all

After I collected all 5 pages of fungi, I am having difficulty to get the page 6 ones. I have been playing for almost 2 weeks now and I only got 2 page 6 fungi. I think I will give up tonight and delete the game if I still stuck with that... So disappointed... Was such a nice game...
