What do you mean when you say "mushrooms"?  Do you mean fungi in general, or do you mean basidiomycetes that form macroscopic fruiting bodies?

Too general and ambiguous guestion! You should aks in detail? Far distance between two objects.

Hi Nina Shishkoff when I say mushrooms I mean fungi in general. thank you in advance 

The culture medium used for the enumeration of actinomycetes is starch-nitrate agar medium of the following composition (g/L): Starch 20 ; KNO3 2 ; K2HPO4 1; MgSO4.7H2O 0.5; NaCl 0.5; CaCO3 3; FeSO4.7H2O 0.01; agar 20 and distilled water up to 1L .
