Good morning Trond and Knut. I can't be 100% sure but I would say, your both yellow Crocus looks like 'Fuscotinctus'. Please note, that in 'Dorothy' the feathering is more suffused than in 'Fuscotinctus' and from what I see on your overview photos I would say they all have a 'clear' feathering. A close-up photo from aside would be better for ID.
Those markings on the outer segments of imperatii reidii are superb.
