Three Unrecorded Species Belonging to Penicillium Section Sclerotiora from Marine Environments in Korea

Species that belong to Penicillium section Sclerotiora are commonly found in various terrestrial environments, but only a few have been reported in marine environments. Because the number of Penicillium species reported in marine environments is increasing, we investigated the diversity of Penicillium section Sclerotiora in marine environments in Korea. Based on sequence analyses of β-tubulin and calmodulin loci, 21 strains of section Sclerotiora were identified as P. bilaiae, P. daejeonium, P. exsudans, P. herquei, P. cf. guanacastense, P. mallochii, P. maximae, and P. viticola. Three of them were confirmed as new to Korea: P. exsudans, P. mallochii, and P. maximae. Here, we have provided detailed morphological descriptions of these unrecorded species.
