I found this greyish mould with a silvery tinge colonizing a dead and decaying branch under Ceratonia siliqua (carob) and Prunus dulcis (almond). Under the micro, it revealed to be a densely intricated mass of hyphae with bunches of spores at the apex (not the tip but along a considerable length). The Hyphae have pigment incrustations and very prominent septa and cell walls. The spores (I need to measure them) seem to be hyaline while only the hyphae are fuscous. The hyphae are smooth but the terminal hyphae (where the spores are attached) are rugose.  

I was thinking that it is something related to Botrys or Stachybotrys. I am culturing the specimen and hope I would not get any contamination.
