Unknown Jumping Spider

At first I thought this little jumping spider was like a Decorator crab, sticking pieces of its surrounds to itself for camouflage. On closer investigation (and a little prod), I realised the spider was dead. It had died in situ and all of the white stuff was fungi fruiting out of it (possibly Akanthomyces - awaiting ID) Look closely at the leaf around the spider. The little white/pale grey spots are the mycelia or hyphae of the fungi.
