[5][7] His personal collection, numbering 12,087 specimens of discomycetes, including 16 types, 27 paratypes, 2 syntypes, and 6,000 microscope slides, was deposited in the Plant Pathology Herbarium at Cornell University (CUP), helping establish that herbarium as a leading center for the study of discomycetes.

[4][5] Durand's collections included 650 types (mostly discomycetes) from other authors and herbaria, currently stored at Cornell University.

As of 2014[update], nine of his species and ten recombinations are still accepted (having not been assigned to another genus or reduced to synonymy under previously published names).

Dudley was a student and assistant under Albert Nelson Prentiss, who was the first head of the Department of Botany at Cornell University.

[7][11] While Durand did not directly mentor any students who would later become professional mycologists, he was well-regarded as an instructor in undergraduate courses.

[1][5] While a student at Cornell, Durand was a member of Sigma Xi, Quill and Dagger, Congress, the Classical Association, and the Natural History Society (of which he was president in his senior year).
