I would like to bring this topic up again, because I think I have dicovered a symbiotic fungus growing in one of my pots of Ceph. 'Giant'. The Ceph. 'Giant' is the clone from Wistuba and I would like to note that it is definately not slow growing, even under very high light. Whether or not this is due to the fungus I'm not sure. But I will try to find out. The fungus in question is brown and threadlike. It seems to grow all around the base of the Ceph. and into the sphagnum. I have only found this fungus in one of my pots of Cephalotus. But I recently innoculated the pot of another Ceph. with this fungus and will report any increases in growth rate.
