Veli Johannes Paavo Bartholomeus Räsänen (24 August 1888 – 16 July 1953) was a Finnish

lichenologist
.

Early life and education

Veli Räsänen was born on 24 August 1888 in

natural sciences and animal husbandry. He was an instructor in the Agricultural School (Kurkijoen maamiesopisto [fi]), as a lecturer from 1921 to 1940. Räsänen became a college lecturer from 1940 to 1953 in Kuopio. He published literature on lichens, including the book Suomen jäkäläkasvio ("Finnish Lichens") (1951).[3]

Räsänen apprenticed with

lichenicolous fungi.[5]

Räsänen was a devoted researcher and worked quickly. He was happy to be sent lichen collections, e.g. from the University of Helsinki Botanical Garden. He also received and completed collections from abroad, defining numerous lichen taxa previously unknown to science. In Kuopio, he became one of the central personalities of the natural history association.[3]

Räsänen made extensive collections of lichens and used a large part of this material for the compilation of lichen exsiccata – dried herbarium specimens. Thus, under his auspices, the exsiccata workLichenes Fenniae Exsiccati, previously published by Johan Petter Norrlin and William Nylander, and later Vainio, was continued by the Botanical Museum in Helsinki. Räsänen compiled 20 fascicles on a total of 1,000 issues during the years 1935–1946. In Kuopio he compiled the exsiccata "Lichenotheca Fennica a Museo Kuopioensi edita", 30 fascicles during the years 1946–1952, comprising a total of 750 issues (25 issues in each fascicle, in the Helsinki exsiccata 50 numbers per fascicle).[3]

Räsänen tried to arouse interest in studying and collecting lichens among younger people. In this respect, mention should be made of his novice book Suomen jäkäläkasvio ("Finnish lichens") (1951), comprising 158 pages and 16 paintings.[3]

Räsänen died on 16 July 1953 in Simo.[2]
