The fonds is comprised of botanical illustrations and field journals by Oluna Ceska, with additional information contributed by Adolf Ceska. This includes, 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.

In addition to the notebooks and reports relating to mushrooms, the fonds includes illustrations of flora on Southern Vancouver Island.

The fonds consists of historical notes, student notes, PhD research data on squid and sardines (including photographic data), lecture notes by subject, and course notes; and files from: Victoria College Biology Department (1958-67), Victoria College Building Committee (1957-58), Victoria College Faculty Association (1952-63), Victoria College Board (1957-63), and Victoria College Faculty and Staff Association, (1949-55).
