very prominent delimitation, like if you cut an apple slantwise and would insert the stipe of the mushroom into it.
Correct but there are as always exceptions to the rule. There are some Phlegmacii that have dry caps and stipes as there are some Myxacii with dry stipes too.

Phlegmacium: the “orchids” of the fungal kingdom. Usually slimy cap and dry stipe, often with prominent marginate bulb.
Cortinarius: some with cystidia, in Europe just C. violaceus, dry overall.
Myxacium: usually slimy cap and slimy stipe, often bitter flesh.
Sericeocybe: often included into Telamonia, silky glossy cap, dryish, very difficult to discern from Telamonia, usually much bigger and not so hygrophanous.
Telamonia: the most difficult subgenus, hygrophanous, often with colored veil, mostly brownish-blackish, rather small for the genus but bigger ones easily to be confused for Phlegmacium or Sericeocybe.
Dermocybe: sometimes treated as a genus of its own right, vividly colored (red, green, olive), can be used for dyeing clothes, all poisonous.

Marginated bulb

means exactly what? Lined, with a defined limit?

Phlegmacium group – cap viscid, stipe not viscid I think that is this the group, right?

If the bulb is not marginate (I thought it was upon looking at the pics) and the cap really was viscid then you have a Myxacium.
Now you would have to taste if the epicutis of the cap is bitterish to bitter or mild. From the photos one cannot rule out other similar species. I am no expert in Myxacium but there is one largodelibutus and maybe in your area there are others too. I only can speak for Northern and Central Europe with Myxacium.

Your suggestions

have all a large bulb, which wouldn’t be the case… this has a stem with the base turned to the side, only a little bulbous. The cross section of the stem is not roundish too, it is flattish.

Let’s see…

There is always something that doesn’t match on descriptions… in this, it is the bottom of the stipe, maybe I should have pulled another and it would be different, or not… god knows. But the cap was viscid, not anything else, it had “nheca” rs.
It has also the marks of the veil on cap, and it is honey yellow. Almost all of the delibutus features match. I am going to read about your suggestions.

this cannot be C. delibutus.
It has a marginate bulb.
I suppose the slimy surface of the cap is coincidental due to humid weather.
The violet-tinged stipe and this bulb and the overall gestalt and color point to something within subgenus Phlegmacium, group Calochroi. Search and confer around the species group of Cortinarius calochrous, C. parvus, C. haasii (which it is not for this species has yellow rhizomorphes at the base of the bulb), Cortinarius caroli and similar ones. Just a hint. There are other very similar groups possible.
