Gavril Stepanovich Nevodovsky was born in the Village Yevminka (Chernigov region, Ukraine) in April 1874 in the family of the village psalm-reader. After finishing school he entered Chernihiv Theological Seminary. But after graduating from the Seminary G.S. Nevodovsky has not become priest. He decided to devote himself to educational work. Since 1897 till 1903 G.S. Nevodovsky worked as a teacher at primary school. At this period he compiled one of the first Ukrainian primers "Ukrainian School", which later on, in 1908 and in 1917, run two editions. In 1903-1911 G.S. Nevodovsky continued education at Novo-Aleksandiysky Institute of Agriculture and Forestry (now Pulavy, Poland). Such long period of education in the Institute can be explained by temporary closing of the Institute during revolution of 1905 (because of numerous student's strikes). Since 1905 till 1908 G.S. Nevodovsky worked as field soil scientist and laboratory assistant at Chernihiv province. Since 1908 he continued his study at the Institute and commenced on mycological researches under the guidance of Professor N.V. Tsinger. Being a student he prepared two mycological works, which were published in "Proceedings of Nov-Aleksandriysky Institute of Agriculture" and in "The Journals of the Circle of Natural Sciences and Agriculture Amateurs of Novo-Aleksandriysky Institute of Agriculture". One of them was devoted to investigation of influence of formalin on spores of smut fungus Ustilago avenae, U. hordei, U. tritici, Urocystis occulta and Tilletia caries, and the other represented the list of 150 species of parasitic fungi of order Peronosporales, Erysiphales, Taphrinales, Uredinales and Ustilaginales, collected in outskirts of Novo-Aleksandriya. At the same time G.S. Nevodovsky began to collaborate actively with prominent Russian mycologist and phytopathologist A.A. Yachevsky, which in 1904-1917 edited "Annual of materials on diseases and damages of cultured and wild useful plants". Fascicles of this edition compiled on the basis of information sent by numerous correspondents from different regions of Russia. During the period of 1908-1910 G.S. Nevodovsky sent to A.A. Yachevsky data on distribution of diseases, caused by parasitic fungi in the Novo-Aleksandriya area. These materials were published in "Annuals" (1909, 1910, 1912). After graduating from the Institute in 1911 G.S. Nevodovsky got an appointment to the post of the head of Phytopathological Laboratory of Tiflis Botanical Garden. He worked in Georgia till 1913. During this period the main subjects of his investigations were fungi agents of different diseases of cultivated plants (cooton-plant, prun, cucumber, field crops). He studied also mycoflora of wild plants. Collecting of materials was conducted in Tiflis and Tiflis district, Gori district (Bakuriani, Tskhinvali), Kutaisi region (Ozurgeti), on the Black Sea coast near Batumi, Tsikhidziri, Kobuleti. In 1913 G.S. Nevodovsky moved to Ukraine and began to work at Smelianskaya Mycological-Entomological Station. The main scientific and practical direction of the Station was investigation of diseases of sugar-beet and their agents. G.S. Nevodovsky commenced on the researches of fungi-agents of sugar-beet diseases in the field conditions and under storing in clamps. He studied Erysiphe polygoni - agent of true mildew of the beet, which was revealed already in 1912 on the experimental field near Tiflis; Phoma betae, Cercospora beticola, Uromyces betae, fungi agents of the black leg, fungi-agents of grey rot. In 1924 Smelianskaya Station was liquidated and G.S. Nevodovsky moved to the Sort-and-Seed Board of Sugar-Trust, where he worked as a mycologist. Since 1927 he worked at the Ukrainian Scientific-Research Institute of Sugar Beet. This period is characterized by prevailing of phytopathological direction in scientific activity of G.S. Nevodovsky. G.S. Nevodovsky also gave the course of plant pathology at Kiev Agricultural Institute. He published numerous papers devoted to pest control and fungal diseases of different cultivated plants (smut of cereals, diseases of lucerne and sugar-beet etc). At he same time G.S. Nevodovsky carried on extended experimental investigations of soil mycoflora in the connexion with wide distribution of such disease as the black leg of sugar-beet. Unfortunately, this work of G.S. Nevodovsky was not finished. In 1930 G.S. Nevodovsky moved to Kazakhstan, where he worked at Alma-Ata stationof Plant Protection, at Zonal Station of Sugar-Trust and gave lectures on phytopathology at Talgar Technical School of Plant Protection (1933-1936). Later on he took part in investigations of the Botanical Sector of Kazakh branch of the USSR Academy of Sciences. Just in this sphere he showed his worth as a mycologist in a full scale. From the first days of work in Kazakhstan G.S. Nevodovsky intensively began to collect fungi from different systematic groups, paying the special attention to representatives of order Uredinales. He got material from different regions of Kazakhstan: territory of Alma-Ata Botanical Garden, Alma-Ata outskirts (river valleys of Small Almaatinka, Big Almaatinka, Batareyka, Gorel'nik, Poganka, Chimbulnak, valleys Aman-Dzheliau, Mynzhilki, Sukhoy Log etc), Alma-Ata district, outskirts of Talgar, Turgen, Issyk-lake, Chimkent, Malovodnoye village, Chilyk and Ili stations, Taldy-Kurgan etc. G.S. Nevodovsky worked out these materials during all his life. His paper on new and little-known fungi species of Kazakhstan was published in the annual "Boatnical Materials of the Department of Cryptogamic Plants of the Komarov Botanical Institute the USSR Academy of Sciences" (1950). In this work G.S. Nevodovsky presented descriptions of new species of rust fungi: Aecidium clematidis-songorica on Clematis songorica, F. inulae-grandis on Inula grandis, A. millefolii on Achillea micrantha, Puccinia alatavica on Ferula alatavica, P. oreophilae on Phlomis oreophila. At the beginning of the 1950s G.S. Nevodovsky prepared for publication the manuscript of I volume of "Flora of Cryptogamic plants of Kazakhstan", devoted to rust fungi. But this work came out only in 1956, after the author's death. In the book were presented the results of 10-year (1930-1940) investigation of rust fungi of Kazakhstan, thorough descriptions of 351 species, original illustrations for 257 species. The contribution of G.S. Nevodovsky in this fundamental edition did not confined to one volume. In fact, for writing every of 13 volumes of "Flora...", authors used materials from extensive collection of G.S. Nevodovsky. His collections were the basis for further description of new species of fungi by Kazakhstan mycologists: Urocystis nevodovskyi (Ustilaginales) on Ixiolirion tataricum, Phyllosticta turangae (Sphaeropsidales) on Populus litwinowiana, Ascochyta galatellae (Sphaeropsidales) on Galatella punctata, Cylindrosporium nevodovskii (Melanconiales) on Dipsacus azureus, Ramularia nevodovskii (Moniliales) on Conium maculatum and others. In 1940 G.S. Nevodovsky moved to Tomsk, where he lectured at Tomsk Forest Technical School, worked at Timiriazevsky Timber Industry Enterprise and then at Tomsk Zonal Flax Experimental Station. In 1943 on the basis of myco-phytopathological materials, collected in forests of Tomsk Timber Industry Enterprise, G.S. Nevodovsky defended PhD Thesis "Phytopathological factors in pine forest of Tomsk district ". During his work at Flax Experimental Station G.S. Nevodovsky studied fungi parasitizing on growing flax and mycoflora of this crop in the process of its retting. In 1946 G.S. Nevodovsky moved from Siberia to Ukraine (to his daughter) and in 1948 together with daughter's family - to Moscow region. In August 1952 G.S. Nevodovsky died. However till the last day of his life he continued to work actively, working up loculoascomycetes of genus Mycosphaerella for the next volumes of "Flora of Cryptogamic plants of Kazakhstan". Unfortunately, according to the plan of edition, this group of fungi was included in XII volume, prepared by another authors and published only in 1987. But a number of new species of genus Mycosphaerella, described by G.S. Nevodovsky, were included in this volume: M. malvinae on Malva sylvestris, M. dauci on Daucus carota, M. dodartiae on Dodartia orientalis, M. heracleina on Heracleum dissectum. The great service of G.S. Nevodovsky in mycology was his activity on edition of fungi exsiccati. He started this work already in XIX century. Exsiccati "Fungi of Russia" were prepared and edited by G.S. Nevodovsky under the editorship of outstanding Russian mycologist V.G. Tranzschel. Altogether were edited 5 fascicles, every consisted of 50 specimens of parasitic fungi of cultured and useful plants: first fascicle was came to light in 1909, IInd - in 1911, III - in 1915 and IV, V - in 1917. During his work in Kazakhstan G.S. Nevodovsky continued this work and in 1935 edited the first century (100) of critically worked up fungi flora, which included 100 herbarium specimens with text and illustrations of fungal agents of cultured and wild useful plants of Kazakhstan. It was brought out by Kazakh Institute of Plant Protection. After retiring on a pension, G.S. Nevodovsky decided to edit Exsiccati "Fungi of the USSR" through the Moscow Naturalists Society. G.S. Nevodovsky prepared the first fascicle with 25 species and selected materials for the next fascicles, but had not time to complete this work. Moscow Naturalists Society executed this work: in 1952 the first fascicle came to light (25 species), in 1954 - the second and the third fascicles (25 species each). In addition to exsiccataes, G.S. Nevodovsky collected during his life the huge herbarium of fungi. The part of private herbarium of G.S. Nevodovsky was, unfortunately, lost during frequent removals. But more then 17,000 specimens G.S. Nevodovsky handed to Kazakh State University (Alma-Ata). In 1953, after Nevodovsky's death, his family passed some herbarium materials, in particular on genus Mycosphaerella, to the Herbarium of fungi of the Komarov Botanical Institute the USSR Academy of Sciences. The contribution of G.S. Nevodovsky in mycology was highly appreciated in opinions about his work of such prominent scientists as V.G. Tranzschel, N.A. Naumov, and A.S. Bondartsev. Lists.
