ResumoThis is the first report on ultrastructural observations of nivicolous myxomycete fruiting bodies with cyst-like bodies.One specimen had immature fruiting bodies of a Lamproderma sp.just after spore cleavage.Using light microscopy and scanning and transmission electron microscopy, countless cyst-like bodies were observed inside of the developing spores, capillitium, columella and stalk.A second specimen consisted of mature fruiting bodies of L. echinosporum.Outward appearance of the fruiting bodies was normal with numerous cyst-like bodies inside the entire fruiting body.The cyst-like bodies in both myxomycete specimens have a common morphology: 5-6 μm in diam, being transparent under light microscopy and densely warted by SEM and TEM observation.The partial sequence of the 18S rDNA gene of the first specimen suggested that cyst-like bodies were in the Cryptomycota (including Rozellida), placed at the root of a fungal clade.
