A new stipitate species of myxomycete of the genus Licea is described based on material from arid areas in Argentina and Chile. It was isolated from moist chamber cultures and found fruiting on field collections, usually on the same substrate, Puya sp. (Bromeliaceae). It differs from all described species in the genus in that it has stipitate sporocarps with dehiscence by defined preformed platelets and a smooth inner peridial surface. The new species has polyhedral, yellow spores with a uniform thick spore wall and dense warts except on irregularly dispersed raised bands with fewer warts, visible by SEM, an ornamentation not previously observed in the genus. Life-cycle events are described and illustrated, from germination to sporulation, based on moist chamber and agar cultures. The morphology of the myxomycete specimens was examined with scanning electron microscopy and light microscopy, and both light and SEM micrographs of relevant details are included.

Daniel, John W. (University of Wisconsin, Madison) and Harold P. Rusch. Method for inducing sporulation of pure cultures of the myxomycete Physarum polycephalum. J. Bacteriol. 83:234-240. 1962.-Techniques for inducing sporulation of pure cultures of Physarum polycephalum are described. Small plasmodia grown in agitated culture were harvested, allowed to fuse into large plasmodia (1.3 g wet weight each), and, after incubation in the dark on a salts medium, exposed to light for 2 hr. The ensuing formation of sporangia containing spores was complete after 12 to 16 hr. The obligatory conditions for sporulation are: (i) an optimal growth age occurring just prior to the maximal growth of the organism and at a time when nutrients in the medium are exhausted; (ii) 4 days of incubation on a medium containing only inorganic salts and niacin or tryptophan; and (iii) subsequent illumination with light of wavelengths between 350 and 500 mmu.

Non-mendelian inheritance of mitochondrial DNA and ribosomal DNA in the myxomycete, Didymium iridis.Molecular & General Genetics : MGG Aug 1988The inheritance of both the mitochondrial DNA (mtDNA) and the nuclear-encoded extrachromosomal ribosomal DNA (rDNA) has been studied in the myxomycete, Didymium iridis,...
The inheritance of both the mitochondrial DNA (mtDNA) and the nuclear-encoded extrachromosomal ribosomal DNA (rDNA) has been studied in the myxomycete, Didymium iridis, by DNA-DNA hybridization of labeled probes to total DNA at various stages of the life cycle. Both the mtDNA and rDNA populations rapidly become homogeneous in individuals, but there is a qualitative difference in the patterns of inheritance of these two molecules. One parental rDNA type was preferentially inherited in all crosses; selective replication of this molecule is tentatively proposed as the mechanism of inheritance. In contrast, either parental mtDNA type could be inherited. Since the inherited population of parental mtDNA molecules are not partitioned into cells in this coenocytic organism, no known mechanism of inheritance can explain the rapid and apparently random loss of one parental mtDNA type in individuals.

The enigmatic Semimorula liquescens E.F. Haskins, McGuin. & C.S. Berry has been isolated repeatedly from dried infructescences of Lythrum salicaria collected from Seattle and Kirkland, Washington. Detailed developmental, morphological and ultrastructural studies suggested that it represents a taxon within Mycetozoa, closely allied with Myxogastria (Myxomycetes) but with unique characteristics. Phylogeny based on two genes places it with confidence in family Echinosteliidae. This species differs from a typical Echinostelium in the way spores germinate and in the lack of a stalked sporophore, the latter being a secondary loss. Semimorula liquescens therefore might be a useful negative model to search for genes inducing stalk formation during sporulation.
