Nottinghamshire opener Jake Libby made his second half-century in successive Championship matches as the hosts built a potentially match-winning lead over Lancashire on day two at Trent Bridge.
On a day when they were knocked off the top of Division One by Warwickshire's three-day win over Surrey, Lancashire began by being bowled out for 276.
Libby then made 54, backed by an unbeaten 51 from Samit Patel.
Steven Mullaney and Michael Lumb both made 43 as Notts closed on 303-5.
Lancashire added just three runs before Notts' new signing Imran Tahir closed out the innings with the eleventh ball of the day, trapping fellow leg-spinner Matt Parkinson lbw to finish with 4-81.
Notts then made a positive start, reaching lunch on 120-1, for the loss of Mullaney, captaining the hosts against his former county.
Neil Wagner had Libby caught behind for his lunch-time score of 54, to follow his 59 against Warwickshire last week.
Greg Smith then fell to Kyle Jarvis for 30, before Lumb and Brendan Taylor (37) put on 74 for the fourth wicket.
Patel then added a further 62 runs with stand-in wicketkeeper Riki Wessels, who ended the day on 25.
Nottinghamshire opener Jake Libby told BBC Radio Nottingham:
"I'm pleased that a little bit of consistency is coming into my game. That's two weeks now.
"I've had a few other 30s and 40s, where I haven't cashed in. I'm a little bit disappointed in that regard, but obviously it's nice to put a score on the board.
"We put the bad ball away nicely and hit the gaps at the start and obviously Steven Mullaney plays that way anyway."
Lancashire captain Steven Croft told BBC Radio Manchester:
"We are a little bit disappointed. We bowled a bit indifferently.
"We started the first session slowly but came back into it in the second session and could have had more reward but we slightly lost it towards the end.
"Overall, a frustrating and slightly underperforming Lancashire side."
