Rubbish in brother's collection (3)

I believe the answer is:

rot

'rubbish' is the definition.
(I've seen this before)

'in brother's collection' is the wordplay.
'in' indicates a hidden word.
'ROT' is hidden within 'brothers collection'.

(Other definitions for rot that I've seen before include "'Decay, decompose (3)'" , "Decay in grotesque way" , "Cobblers" , "SECOND PART OF 25" , "bunk" .)

I've seen this clue in The Telegraph.
