Scolecostigmina chibaensis, described from Japan, is a caulicolous and plant pathogenic fungal species on Pinus spp. In this study, a taxonomical revision of S. chibaensis based on the morphological characteristics and phylogenetic relationships using nrDNA ITS and LSU is conducted. As a result, S. chibaensisis transferred to the genus Kirschsteiniothelia. And, this is the first record of a Kirschsteiniothelia species in Japan.
