Шаблон:Short description Шаблон:Speciesbox
Aceria pseudoplatani causes the sycamore felt gall that is found on the leaves of sycamores (Acer pseudoplatanus) or Norway maple (Acer platanoides),[1] and is caused by an acarine gall-mite.
Appearance
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 which later turns brown.[2][3] The bulge is due to the erinae or hairs being wider at their top. In purple-leaved varieties of the sycamore the patches are pink.[1] The size of the felt-like patches is variable and they may appear from late spring onwards.[4]
Distribution
The sycamore felt gall is quite common and is widespread through the United Kingdom[5] and is also recorded from Poland, Belgium and Germany.[6]
