What Are Fuzzy White Spots On Trunk Of 40 Yr Old Wisteria?

1st yr trimming new growth daily so canopy is thinner than usual. Very hot month. Recently added new wiring to lift weight of heavy branches. 3 distinct trunks. Never noticed the fuzzy white patches on trunks/thick branches in 30 years. Few leaves on top yellow with brown spots. Do not want to lose this beauty.
