Myxomycetes of Taiwan XVI. One New Species and One New Record of Physaraceae

One new species and one new record in the family Physaraceae are described and illustrated by light and scanning electron microscopy. Badhamia formosana Liu and Chen sp. nov. was found on mosses that grew on barks of dead wood or on barks of living trees of broad leaves. This species is characterized by the stipitate, white and limy fruiting bodies, large spores and limy capillitium. Fruiting bodies of Physarum braunianum, a new record of Taiwan, were obtained from moist-chamber culture of leaf litters. They are easy to be recognized by the brownish orange-colored sporangia which are sessile and always constricted at base, and capillitium with angular lime nodes often in concolorous with the peridium
