Meyer Lemon Trunk Issue: Photo Needed for Diagnosis

8-year-old potted Meyer lemon has “staley” outer trunk/branch problem on old wood only; pruned spots have grass-like growth. Bore 80+ lemons last year.

Need Visuals

Without a photo, diagnosis is speculative. Could be scale, fungal growth, or abiotic issue. Send clear, close-up images of affected bark and overall tree. Note when problem appeared and current foliage/fruit status.
