Drama in the France/Italy match:
Pennetta won a knife-edge encounter 2-6, 7-6 (9/7), 6-4 in Orleans, northern France, to give the visitors a 1-0 lead in their Fed Cup World Group One tie.
But Mauresmo said she felt Pennetta should have been kicked out after appearing to insult the chair after a shot she thought was good was ruled out in the crucial second set tiebreak.
"At that moment, I didn't really see and cotton on," said Mauresmo, who indicated that when she did look up Pennetta appeared to have mouthed an insult at the chair, flicking her middle finger for good measure.
"She gave the finger - she should have been removed right away," insisted former Wimbledon and Australian Open champion Mauresmo.
The point gave the Frenchwoman a match point but in the hullabaloo she served up a double fault and then slumped to defeat.
Pennetta, who did receive a warning for her conduct, said she was sorry afterwards.
"I am not pleased with myself but that's the first time such a thing has happened to me - it was a gruelling match from the start and I lost control as I really thought the ball was in," said the Italian.
French skipper Nicolas Escude was angry that the Italian was not handed a stiffer penalty.
"It's amazing. When (former French footballer Zinedine) Zidane loses it he gets sent off. Great, everything's possible. Magnificent, you can do as you like," Escude said in allusion to Pennetta.
