Huge mushrooms will not grow a stem an odd number of blocks tall with the stem more than 6 blocks tall.
I know that the "extra huge" mushrooms is a cool feature added in 1.10 but I found a generation bug that only works with "extra huge" mushrooms, their stem won't grow an odd number of blocks tall (if your counting the top of the mushroom, the whole mushroom wont grow an even number of blocks tall). I found many huge mushrooms and measured their stems, only the mushrooms that were more than 7 blocks tall had this bug. In the screenshots I added glowstone to make it easier to observe the heights of the mushrooms.
its simple to reproduce: look for huge mushrooms more than 7 blocks tall and observe their height, you will see how I described them.

Can you explain why this is a bug, and not just a quirk or feature of the world generator? As far as I'm aware the same applies too other things such as trees, where they don't grow to certain heights.
i reported this because it is impossible to get a huge mushroom 9, 11, or 13 blocks tall but is possible to get a huge mushroom 10, 12, or 14 blocks tall, that seemed to be pretty buggy to me, i will check again in case this is a duplicate.
Edit: couldn't find a duplicate or related bug. (I am NOT stating that mushrooms should grow even taller because that would be a feature request)
Edit 2: found 2 mega taiga trees and one of them was 1 block less tall than the other. what i am stating is that the mushrooms have separation limits when growing "extra huge", causing an increased chance of identical height mushrooms when more than 7 blocks tall, making it look unnatural.
Mushroom stems may only be 4, 5, 6, 8, 10, 12 blocks tall.
int i = random.nextInt(3) + 4; if (random.nextInt(12) == 0) { i *= 2; }Huge mushrooms now have a 1 in 12 chance of being double-height. Thus, the extra-huge mushrooms will only have even-height stems, because no matter what whole number you pick, doubling it will always result in an even number.
