The Brown Brogiotto Nero is a misnomer.
The UCD Barnisotte is the real thing,but diseased and sensitive to adverse climatic conditions.
The Nero 600M,is a Black fig,Indeed "Nero".(black),when ripe,healthy, but smaller in fruit size than UCD Specimen
For me here ,in NJ,Nero 600m,is doing very well,for the difficult climate,yet,
I wish i could have a UCD type specimen healthy enough to grow here.
Pix 1,2,3,:Barnisotte,UCD The real thing
Pix 4,5,:Nero 600m, a very nice Nero in deed but not Barnisotte.
