Do spores become dikaryotic inside a solution or after they sit on top of each other on a surface?

Do all spores join their nucleus inside a solution or on top of each other when they sit on a surface or do they have to germinate first?

Spores only have 1 set of genes. They're gametes so they can't 'swap' genes. They can just germinate and mate.

lol let me word this better i was baked at the time
do they only mate after germination and tissue\clamp formation or is this process predetermained threw the cell wall
like do they attach to each other at a really early age based on where they made contact with each other or does it take time for these spore traits below to occur from actual tissue growth
i found this on wiki to help me explain what i ment, im trying to isolate the alete spores before they mate with the rest and change type
Under high magnification, spores often have complex patterns or ornamentation on their exterior surfaces. A specialized terminology has been developed to describe features of such patterns. Some markings represent apertures, places where the tough outer coat of the spore can be penetrated when germination occurs. Spores can be categorized based on the position and number of these markings and apertures.
Alete spores show no lines.
In monolete spores, there is a single narrow line (laesura) on the spore.[4] This indicates the mother spore split into four along a vertical axis.[citation needed]
In trilete spores, each spore shows three narrow lines radiating from a center pole.[4] This shows that four spores shared a common origin and were initially in contact with each other forming a tetrahedron.
[citation needed] A wider aperture in the shape of a groove may be termed a colpus.[4] The number of colpi distinguishes major groups of plants. Eudicots have tricolpate spores (i.e. spores with three colpi).[5]

Monokaryons can be fertilized by other dikaryons, other monokaryons and spores with a compatible mating type, through contact.
Spores do not become dikaryotic without germination, contact and compatibility.
Some studies have strongly evidenced that most dikaryons are not a result of mon-mon mating (as it were) but rather tend to be interactions of monokaryons with spores and dikaryons. Two monokaryons meeting in-nature is relatively uncommon, at least according to some.
Some fungi even produce monokaryons naturally at the leading edge of the dikaryon, other fungi and known cultures like some Pleurotus lines also spontaneuously produce monokaryon culture from dikaryonic culture. This process is called "de"-dikaryotization and the monokaryons produces are called "neo"-haplonts and are known both from nature and able to be induced (by ppl) for purposes of identification and mating.
As such and to specifically answer your question:
Quote:
Do spores become dikaryotic inside a solution?
No, but if they germinate the resulting monokaryons can be rapidly and easily fertilized by the other spores in suspension.
The same goes for if they sit atop one another. If they merely touch and are just spores: they do not fertilize one another. There must be a monokaryon for fertilization to occur. Many papers have noted consistent macroscopic and growth distinctions between monokaryonic and dikaryonic cultures of the same species.
Spores are heavier than water and do not create solutions because they are not soluble. They will settle and sit on top of one another in the water, where there is a surface unless mixed about by shaking or a thickener, this makes spore water a suspension. The phrase "spore solution" is nonsensical despite being widely used.
This should answer the question.
