The gall forms a bulge on the upper epidermis, where the pigment colour is usually light yellow to start with and brown later on in the year. The appearance on the lower epidermis is a concavity with cream- or white- coloured felt-like mat that later turns brown. The bulge is due to the
221:, or hairs, being wider at their top. In purple-leaved varieties of the sycamore, the patches are pink. The size of the felt-like patches is variable, and they may appear from late spring onwards.
