“…and short plasmodiocarps, the eggshell-type peridial lime made up of cup-like crystals by SEM (Fig. 6A) and the capillitium containing crystalline lime all match the description by Keller & Schoknecht (1989). This is the first record of this species from Argentina.…”

“…The sporangia cultured on agar had darker peridia relative to the field-collections, especially in the case of P. album. Similarly, when Physarales species were cultured on the semi-defined or defined media, mature sporangia usually had deeper color peridia or stalks due to the lack of lime deposits (Chen et al 2013;Keller and Schoknecht 1989;Koevenig 1964;Liu et al 2010). It was reported that Physarales species had a higher pH optima relative to those preferred by members of Stemonitales (Stephenson 1989).…”

The plasmodial slime molds is the largest group in the phylum Amoebozoa. Its life cycle includes the plasmodial trophic stage and the spore-bearing fruiting bodies. However, only a few species have their complete life cycle known in details so far. This study is the first reporting the morphogenesis of Didymium laxifilum and Physarum album. Spores, from field-collected sporangia, were incubated into hanging drop cultures for viewing germination and axenic oat agar plates for viewing plasmodial development and sporulation. The spores of D. laxifilum and P. album germinated by method of V-shape split and minute pore, respectively. The amoeboflagellates, released from spores, were observed in water film. The phaneroplasmodia of two species developed into a number of sporangia by subhypothallic type on oat agar culture. The main interspecific difference of morphogenesis was also discussed.

Myxogastrea is a group of eukaryotic microorganisms included in Amoebozoa. Its life cycle includes two trophic stages: plasmodia and myxamoeflagellates. However, only about 102 species have their complete life cycle known in literature and only about 18 species have their plasmodial axenic culture accomplished in laboratory conditions. The research presented herein involved culturing of Physarum galbeum on the water agar medium. The events that transpired during its life cycle including spore germination, plasmodia formation, and sporocarp development were documented especially the subglobose or discoid sporotheca and the stalk formation. The spores germinated by the V‐shape split method to release a single protoplasm. Yellow‐green pigmented phaneroplasmodia developed into sporocarps by subhypothallic type. The present article gives details of the sporocarp development of P. galbeum and its plasmodial axenic culture on solid and liquid mediums.
