Aceria macrocheluserinea agg.
The mite causes an erineum to form on Field Maple (Acer campestre), usually on the leaf underside. The mites live amongst the hairs of the erineum, which is white to begin with, then pink and then brown; the individual hairs (use a hand lens) are mushroom shaped with rounded bead-like tips.
