Try this. It works very well with Botrytis, which also
produces polyglucan (although maybe not as much as
Sclerotium). Polysaccharides are eliminated by
precipitation with CTAB.
A simple and efficient protocol for isolation of high
molecular weight DNA from filamentous fungi, fruit
bodies, and infected plant tissues.
