I Have A Sick Holly Bush

The tops of my Holly bush have a sooty black substance and underneath, there are long white (about 1/2 inch) “things”, at lease 6 on each leaf. The leaves are not falling off and there is new growth from the stems. Did some research, but unsure of the problem, and how to take care of it. HELP !!! We never had this problem before. Thanking you in advance for your assistance.
