It looks for me as a mychorriza fungus. The tips of the roots are white. So they the plant is not sick.
We only see the roots, not the conifer.

I knew this "white foliage" from the conifers in containers in the nursery. Especially of pines. They live together with a fungus, horticulture term is mycorhizza (Not sure as it is the right spelling in English). The fungus help the roots of the conifers to get the nutrients from the soil. The fungus build fine root hairs around the roots of the conifer.

Mark - speaking of mychorrizal fungus have you ever tried the commercial one especially for bulbs? It is sold here under the Myke label.
