Lynda Casey had been reported missing to police by family members on Monday 10 August after vanishing on Saturday morning. Her body was discovered five days later by the Metropolitan and Sutton police.
A post-mortem examination revealed the mother-of-two had suffered severe head injuries but pathologists were unable to determine the cause of death.
Her car was spotted in a car park near a pub, which sparked the police search, ending in the dense undergrowth of Great Solom's Wood, an area of Barnstead Woods, near Chipstead.
Collegues at Sutton College said she would be dearly missed.
College director of administration Cherry Yates said: "Obviously, it is very sad, and our thoughts and prayers are with her family. She was highly regarded by staff and pupils here."
A 50-year-old professional gardener has been arrested and charged with her murder.
He was stopped on 12 August on his way to Somerset and taken to Woking police station.
Appearing at South East Surrey Magistrates' Court on Saturday (15 August), he was remanded in custody to appear at the Old Bailey on 1 September.
No plea has been entered.
