Polytrichum species?

Observation - Polytrichum species? - Global. Description: I'm just wondering if anybody knows what species this is. I found it on a grassy/heathland part of the wasteland. The soil is usually acidic around here but considering that is an old landfill site it may not be at that particular spot but I don't know. T

I'm just wondering if anybody knows what species this is. I found it on a grassy/heathland part of the wasteland. The soil is usually acidic around here but considering that is an old landfill site it may not be at that particular spot but I don't know. The spores in the capsule were bright green. Can anyone identify it from these photos please.
