Mary and all,
What you are seeing is apparently a type of fungus that liked to grow on the Ecsaine. Another tech had reported it, and said that they had it analyzed by a lab which found it was a fungus. It mainly seems to happen in relatively humid environments.
It seems that the Ecsaine material was changed to discourage this growth some years back – I don't know when.
Just vacuum it out, the material is still functioning fine.

Oh Yeah - looks like the ecsaine "beard" . Those hammers need serious re-shaping and the shanks sitting on the rail indicate a need of regulation I believe a full set of backchecks with buckskin costs about $99 from Schaff

I don't have pictures for the Kawai UST8C but this one is from a 26 year old Samick SG172 grand. The back checks are shredding on this picture. You can see it's on the hammers and rest rail.
