White mold by sclerotinia sclerotiorum can give white cottony growth. Open the stem and look for hard black structures (sclerotia)

Is the black substance growing on the tutors? and maybe infecting tomato plants? or vice versa? please provide more picture with detailed symptoms and some indications on the spread of the observed anomalies

It looks like wilt disease. The wilting of tomato may occur due to following pathogens
1. Bacterial wilt caused by Ralstonia solanacearum
2. Fusarium wilt caused by Fusarium oxysporum
3. Verticillium wilt caused by Verticillium albo-atrum.

To know the exact causal organism please provide the following information:
a. Is wilting one sided?
b. Is there any discoloration of vascular tissue? (Cut the infected stem near base longitudinally to see brown vascular discoloration)
c. Percent of field infected?
d. Recent agronomic practice carried.
e. Weather conditions etc.

Also you can do ooze test by cross cutting infected stem and dip in a glass of water. If it is bacterial wilt a white, slimy substance will ooze into the water within few minutes.
