The fonds consists of eight field journals of mycofloristic (mushroom) surveys with detailed illustrations by Oluna Ceska. Each specimen has been labelled by name, as well as by the location, date, and substrate where it was found. Additional observations include physical characteristics, smell, size, and spore size. The research focuses primarily on the southern Vancouver island region. Many of the studied specimens are from Observatory Hill, Victoria. Additional research locations include the Gulf Islands, Haida Gwaii, the BC mainland, the Yukon, Washington, and Oregon.
The fonds also consists of 9 survey reports of macrofungi on Observatory Hill that were researched and compiled by Oluna, with photos of specimens taken by Adolf. The reports describe species of fungi that were found, their location, as well as environmental factors that impact fungi growth.
