Note 57 — Chapter V · Morphology and Systematic Botany under the Influence of the History of Development and the Knowledge of the Cryptogams. 1840-1860.

C. G. Nees von Esenbeck published his ‘System der Pilze und Schwämme’ in 1816; Th. F. L. Nees von Esenbeck, in conjunction with A. Henty, a ‘System der Pilze’ in 1837. The first (1776-1858) was for a long time President of the Leopoldina, Professor of Botany in Breslau, and one of the chief representatives of the nature-philosophy. Elias Fries, born in 1794, became Professor of Botany in Upsala in 1835; he died in 1878. Léveillé (1796-1870) was a physician in Paris. August Joseph Corda was born at Reichenberg in Bohemia in 1809, and became custodian of the National Museum in Prague in 1835; he undertook a journey to Texas in 1848, from which he never returned, having probably perished by shipwreck in 1849. Weitenweber, in the ‘Abhandlungen der Böhmischen Gesellschaft der Wissenschaft,’ Bd. 7, Prag, 1852, gives a full account of this eminent mycologist. Corda was the first who thoroughly applied the microscope to copying and describing every form of Fungus that was known to him, and especially the minuter ones. His ‘Icones Fungorum hucusque cognitorum’ (1837-1854) are still an indispensable manual in the study of the subject.
