Are you sure that they are fungi? Bacteria are pretty resistant to
colchicine. Or may be those fungi cannot permeate colchicine well.
Another possibility is that colchicine was inactivated after a year.
Or may be you have a contamination of Fusarium colchicinofilus Mal., a
fungus that need colchicin to grow when it is not a symbiont of the giant
moth of the Amazonas.
Lo que no cabe duda es que eres un guarro.
