IAN Holloway slammed referee Stuart Attwell after he failed to give Millwall a penalty during their 1-0 defeat to Bolton on Friday night.
The Premier League official waved away the Lions' appeals when Lee Gregory went down under the challenge of goalkeeper Andy Lonergan during the second half.
Holloway said Attwell should have pointed to the spot or booked Gregory for diving.
Darren Pratley then hit the winner for Bolton as Millwall's miserable home run continued.
"It's very, very upsetting and very, very annoying," said Holloway.
"If that's not a foul on Gregory, if he's not beaten that last man and now has a goalscoring opportunity, then he should've been booked for diving.
"I just can't believe it. It was so clear to their bench – they know it should have been a penalty and a red card.
"That would have changed the complexion of the game.
"Book my man for diving or send off the keeper – don't just wave your hands in the air and play on. Play on for what?
"Couldn't the linesman see it? The fourth official was with me and he saw it. Bolton's bench saw it. You can't not make a decision there.
"You only had to see the look on their faces [the Bolton bench]."
But Holloway refused to attribute Millwall's loss to that controversial moment and instead criticised his side's poor organisation leading up to Pratley's strike.
"I'm fuming because we got a free kick but given where it was and where we took it from, we didn't get our shape right," he said. "The wrong player took it.
"We didn't get that set up correctly and they go and score.
"We lost the game because we can't take a free kick like that. Danny Shittu took the free kick but he should have been on the end of it.
"We didn't sort ourselves out. The players have to focus on their jobs. I've never played here but maybe it's hard to keep your confidence."
Holloway added: "At the start of the game, that didn't look like the team that I saw in training yesterday. We've got to stand up and be counted, and be positive.
"We've got to get forward but I saw some nerves that I didn't see last week at Brighton. I spoke to them at half time and thought we did a bit better.
"We were unlucky with one great move in the first half when Angel Martinez put it wide but they looked more relaxed than we did.
"I'm really frustrated for everybody. The fans are trying not to moan but it's difficult because we promised so much at the start of the season.
"I'm going to have to look at January and get some people in who can deal with this. You've got to have the right character to play here.
"We've got a lot of people out-of-contract and we hoped they'd all be playing for a new one – showing off and showing how good they can be.
"There were nerves out there and we've got to get past that.
"I didn't want to change the team from last weekend but Mark Beevers was ill and so was Ed Upson."
Despite club captain Alan Dunne's return to the starting XI, Shittu was named as skipper.
Asked to explain that decision, Holloway said: "We won last week when Danny was captain and to me Danny is the essence of this club.
"Dunney has been brilliant for me but I need 11 captains. I need to be a leader as well but I want them to step to the plate."
