ResumoFallen leaves were collected from the Finnish trees Alnus gtutinosa & A. incana, Betula pendula & B. pubescens, Picea abies, Pinus sylvestris and Populus tremula , and used to establish 400 moist chamber cultures. From these emerged 132 specimens of Myxomycetes belonging to 14 species. One of them, Didymium dubium Rostaf. was also cultivated from spore to spore in artificial media. The three Arcyria species that emerged developed only on coniferous litter and the four Didymium species only on deciduous litter. Echinostelium minitum de Bary is the only myxomycete species that emerged on leaves of all the five trees. Alnus litter gave rise to the greatest number of myxomycete specimens. Betula leaves seemed to be the most unfavourable of the substrates. The common species of Myxomycetes that have appeared only on bark of living trees in the moist chambers set up by the author include Paradiacheopsis fimbriata (G. Lister & Cran) Hertel and P. solitaria (Nann.–Brem.) Nann.–Brem. Species occurring only on deciduous leaves or grains are Didymium difforme (Pers.) S. F. Gray, D. dubium Rost. and D. squamulosum (Alb. & Schw.) Fr.
