Polychaos dubium with fungus

I found two specimens of P. dubium in a fresh sample from the Diepveen in the Netherlands (April 2013), both infected by a long and thin fungus. This fungus resembles Amoebophilus simplex, which parasites on Mayorella (see here). However, the conidia of the Polychaos-fungus are much longer than in Amoebophilus simplex, with sharply tapering ends, while the haustoria look the same.
