fissidens

Observation - fissidens - UK and Ireland. Description: Is this a male reproductive structure shown on the leaf here or something else? There is a hint of a line round the leaves so have gone for F. bryoides but not sure how distinct this line has to be, otherwise it might be F. taxifolius.
