Using tox 1.4.2 and python 2.7 on OSX I get

ERROR: unknown environment 'py32 # Python 3.1 and 3.0 might work as well.'

when running tox with the toxfile here: https://github.com/erikrose/more-itertools/blob/c0339068f094933504d095bb0d2c40577acf7c56/tox.ini

Moving the comment to a different line fixes the issue.

[update by @obestwalter to clarify the problem]

Example, comments like this will make tox fail, because it does not interpret:

[tox]
skipsdist = True  # THIS IS NO COMMENT FOR TOX!
envlist = standard-greeting

[testenv:standard-greeting]
deps =
  plumbum # THIS NEITHER!
  flask
commands =
  python -c 'print("Hello, world!")'  # AS YOU SEE IT'S UNIVERSAL!

output:

Traceback (most recent call last):
File "/home/oliver/.virtualenvs/tox/bin/tox", line 11, in <module>
  load_entry_point('tox', 'console_scripts', 'tox')()

well, we could allow comment-recognition for the env-variable i think. We just cannot do it for each line in the ini-file.

Original comment by @RonnyPfannschmidt

tox cannot consider such inline start characters comments
without breaking legitimate dependency listings and/or commands

So this is a wontfix then, I guess.
