The University of North Carolina Herbarium (NCU) has catalogued approximately 70 fungal specimens collected by Boris I. Krawtsew. As our collection continues to be catalogued as part of the Macrofungal Collections Consortium (MaCC), it is likely that other specimens collected by him will be found.  While his name can be transliterated from Russian in many ways, the form most commonly seen on labels in NCU’s collection is “Krawtsew.”

Other herbaria in North America that hold specimens collected by him include NY (New York Botanical Garden), BPI (United States National Fungus Collection), and MICH (University of Michigan).

Boris Ivanovich Krawtsew was born in Omsk in 1902.  Oleg Milishchenko, archivist at the Peter Stolypin Omsk Agrarian University, has an “educated guess” that he was the son Ivan Pavlovich Krawtsew, a mining engineer, and Sophia Filippovna Krawtsew (Izergina), an Omsk business woman.  Boris Ivanovich was educated in Omsk and graduated from the eighth grade of the gymnasium.  Milishchenko continues, “On February 18, 1920 [Boris Ivanovich] was arrested by the Cheka [Soviet State Security] and sentenced on 13-14 April, 1920 on charges of escaping from Soviet power.”  He was also convicted of aiding the White Army and the government of Admiral A. V. Kolchak.  Krawtsew was sentenced to six months in the concentration camp, but was released under an Amnesty on May 5, 1920,” according to Milishchenko.

Boris Ivanovich’s sister, Nadezhda Ivanovna Krawtsew, graduated from the Siberian Institute of Agriculture and Forestry in the 1930’s and worked as a plant breeder for the Altai experimental station.

Boris Ivanovich graduated from the Department of Phytopathology of the Siberian Institute of Agriculture & Forestry** in Omsk ca. 1929.  Krawtsew joined other notable mycologists such as K. E. Murashkinsky, N. I. Lavrov, M. K. Ziling, and V. P. Dravert associated with that Institute.  In the 1920’s and 1930’s the Institute sponsored research expeditions to the southern Tomsk Oblast, to northern Kazakhstan, Khakassia, Altai, to the Sayan mountains, and to the valleys of the Vasyugan and Chulym.

Boris Ivanovich worked in western Siberia and focused on fungal diseases of the economically valuable Siberian fir (Abies sibirica). Areas that Krawtsew collected specimens and surveyed tree health included:

1924:  Oyrotia (known since 1937 as Gorny Altai Autonomous Region, Russian Federation)
1927:  Biysk district (in the forests of the Altai Mountains)
1929:  Archinsk district (Tisulsky rayon) and Tarsky district (Tarsky rayon & Ust-Ishim rayon)
1930-1931:  in the former Kuznetsk district within Gornaya Shoria and Kuznetsk areas, as well as in the former Tomsk district along the Chulym River
1932:  in the Sayan Mountains and in Kuznetsk Alatau (Khakass Autonomous region & former Minusinsky district) 

Specimens collected by Krawtsew were sent to the Phytopathological Laboratory of the Siberian Institute of Agriculture & Forestry and were identified and processed under the direction of Professor K. E. Murashkinsky.

In 1933 Krawtsew authored “Fungal diseases of Siberian fir” (Кравцев Б. И. Грибные болезни сибирской пихты. Омск, изд. Сибирского института сельского хозяйства и лесоводства, 1933). 

  “Unfortunately, [about] the fate of Krawtsew, I know nothing,” says Milishchenko.  North American herbaria have no specimens collected by Krawtsew dated later than 1938. 

** Siberian Institute of Agriculture & Forestry became the Siberian Institute of Agriculture in 1933.  Today it is known as the Peter Stolypin Omsk Agrarian University.
