Two new species of Diacheopsis from China

Two new species from China in the myxomycete genus Diacheopsis are described and illustrated. The distinctive characteristics of Diacheopsis griseobrunnea sp. nov. are solitary and grayish brown sporocarps, sparse and uniform capillitium, and minutely warted spores; those of Diacheopsis gigantospora sp. nov. are large spores marked with long spines, a capillitium that forms a very loose network, and wide tubular threads. Differences between the new species and closely related taxa are discussed. Type specimens are deposited in the Microbial Cultures Center of Nanjing Normal University.
