Spores are resistant to desiccation and may still be viable for germination when they are several years old. [2]
The perpetual saturation of wood with water also inhibits dry rot, as does perpetual dryness. [9] Dry rot would appear to be a paradoxical term seemingly indicating decay of a substance by a fungus without the presence of water.

Very short patch (VSP) repair is a DNA repair system that removes GT mismatches created by the deamination of 5-methylcytosine to thymine.This system exists because the glycosylases which normally target deaminated bases cannot target thymine (it being one of the regular four bases in DNA).
