After looking at the images, I have to say it does match the pattern of honey fungus. I think you need to dig one of them up and inspect the roots. The rhizomorph(s) which move between plants are not always easy to find - they could be under the fence line, for example. I occasionally see one crossimg my veg plot. However, they are usually obvious when you dig up the rootball of an infected shrub. It could be other root pathogens such as phytophthora rather than HF. The cypress looks too far away to have any effect and all they really do is make the soil dry and can't have caused all of this damage.
