Wycombe have confirmed that manager Peter Taylor has left the Coca-Cola League One club by mutual consent.
The former England Under-21 manager, 56, guided the Chairboys to promotion from League Two last season at the first attempt but has paid the price for a poor start to the season.
Club owner Steve Hayes said: "Peter is an honourable man and he knew that it was time to move on. He came to me and said he was very disappointed with the way the season has begun and understood that things had to change."
He added: "He leaves with our thanks and best wishes for the future and I want to place on record our gratitude for the excellent job he did for us last season in getting us promoted."
The search for a new manager at Adams Park will begin immediately, with head of youth development Richard Dobson taking caretaker charge.
Assistant manager Junior Lewis has also left the club.
Hayes is confident that the club - who boast the likes of Martin O'Neill, John Gregory and John Gorman as former managers - will continue to attract high calibre applicants.
He said: "Wycombe have a good reputation for appointing managers and I am sure that we will get plenty of high calibre applicants.
"Peter's successor will inherit an excellent squad of players and with 35 games still to play, we are confident that our league position will improve."
Wycombe have scored just nine goals in 11 league games and travel to Gillingham on Saturday languishing in 23rd place in the table.
