 The so @-@ called anamorphic or imperfect fungi are those that seem to lack a sexual stage in their life cycle , and typically reproduce by the process of mitosis in structures called conidia . In some cases , the sexual stage — or teleomorph stage — is later identified , and a teleomorph @-@ anamorph relationship is established between the species . The International Code of Botanical Nomenclature permits the recognition of two ( or more ) names for one and the same organisms , one based on the teleomorph , the other ( s ) restricted to the anamorph . In 2004 , researchers reported a connection between C. geaster and the appearance of blackish @-@ brown tufted structures on rotting wood . By comparing the internal transcribed spacer region of the nuclear ribosomal DNA from the two organisms , they established a phylogenetic connection between Chorioactis and the fungus they called Conoplea aff. elegantula . However , they were unable to induce the new organism to grow on artificial media , and did not definitively establish a teleomorph @-@ anamorph connection between the fungi . In 2009 , Japanese researchers found a similar fungus growing on rotting logs that were normally associated with the growth of C. geaster ; they were able to grow the organism in axenic cultures from single @-@ spore isolates of C. geaster . They named the anamorph Kumanasamuha geaster due to its morphological similarity with species in the genus Kumanasamuha .
