I have planted Double Duo Zinnia seeds in organic pots and now that the seedlings are around three inches high the compost is covered in a orange fungus. Doesn't seem to be doing any harm at the moment but when I plant out will it affect the plant?

Previous question
I am trying to picture the situation:
By organic pots! do you mean peat pots?
Have the seedlings been pricked out into individual pots?
If not do you intend thinning the plants out at planting out time?
As I see it; I don't think the fungus is a problem, this is probably a result of the pot decaying.
However I think they need thinning out into individual plants because the plants want to be around 200mm (8") apart in the bed to get the best from them.
Sorry I couldn't be more helpful....Tg
