If ammonia is still there at spawning, the compost tells you within days. Spawn runs slowly or stops in patches. DMR lists ink caps, the black inky Coprinus mushrooms, under presence of ammonia and high nitrogen in compost. It ties Oedocephalum mould to ammonia and amines that were not eliminated during pasteurisation and conditioning.
By then nothing in that batch can be repaired, so the lesson belongs to the next one. Check the formulation nitrogen you actually stacked, the oxygen supply during conditioning, and whether your ammonia evidence was honest or convenient.
