Silly man perversely pinching church collection (10)
I believe the answer is:
miscellany
'collection' is the definition.
(I know that miscellany is a type of anthology)
'silly man perversely pinching church' is the wordplay.
'perversely' indicates anagramming the letters.
'pinching' indicates putting letters inside (taking inside).
'church' becomes 'CE' (abbreviation for Church of England).
'silly'+'man'='sillyman'
'sillyman' with letters rearranged gives 'misllany'.
'misllany' enclosing 'ce' is 'MISCELLANY'.
(Other definitions for miscellany that I've seen before include "varied group" , "anthology" , "authors contribute" , "Varied collection" , "potpourri" .)
