The popcorn disease caused by sclerotia forming fungi reduces the productivity of mulberry fruits in worldwide. In Korea, only two species (Ciboria shiraiana and Scleromitrula shiraiana) have been reported as themajor causal organisms and their morphological features are also largely unknown. Hereby, we report thefirst identification of another species (i.e. Ciboria carunculoides) in Korea and detailed features of theiranamorphic stage. Fungi dominantly associated with sclerotia were purely isolated from infected mulberryfruits under the microscope. PCR-amplified DNA encoding 5.8S rRNA displayed 100% similarity to Ciboriacarunculoides. The anamorphic features exhibited the absence of true mycelia. Instead, very short, aseptated,branched conidiophores were directly emerged from sclerotia. Phialides were usually three in number fromeach conidiophore, ampuliform to navicular in shape, slightly curved and tapering towards the apex. Conidiawere produced from phialides and mostly found as one celled, pear shaped, not hyaline with smooth touneven surface walled. Diversely modified features in phialides formed pseudo-mycelial structures aroundthe host tissue. Combined all, current study is the first report of C. carunculoides isolated in Korea and theforemost detailed description of its anamorph stage.
