Last year I made some photos with avocados touched by some stains. They were even more delicious than the regular ones.

What's the name of such stains and how do they form? My guess is that they form because the fruit was hurt but maybe that's just me.

Later edit: A farmer told me it's a disease. Then I've found that it looks quite similar with apple scabs. Is it correct to call this "Avocado scab"? Is it made by the "Sphaceloma perseae" fungus?

Here are the photos:

    $\begingroup$ Well, I guess each kind of damage looks different and distinct from the others, that's why I was asking what kind of specific damage is the one in the photos I referenced. $\endgroup$
