Black gelatinous blobs on Viburnum which erupts violently on touching with water (asco?)

Stephen Martin MifsudHello, I have a very odd finding which is acting as a parasite on Viburnum tinus causing discoloration of leaves (esp near veins) and brownish-black gelatinous blops apparetly on the bristles of the plant along the margin and leaves, then throughout most if the leaf. The blob (about 100-200 um wide) is polished and looks like a droplet of tar.

Now here starts the movie. When this is placed in water, the blob swells and then gets punctured fro 1 to two loci from which there is a jet-like action emitting and dishcarging the contents Including mainly of motile cells, spore-looking, oval bodies, yellow spherical 'cells' and amorpphous bodies (and few crystals too). Now I dont know whit what I am dealing, but I think is it a systematic fungus cause highly infected leaves had white mycelia errupting from vein axils. 

I try to document the organism with photos
