Noteworthy anamorphic fungi, Cephalotrichum verrucisporum, Sagenomella striatispora, and Sagenomella griseoviridis, isolated from biodeteriorated samples in the Takamatsuzuka and Kitora Tumuli, Nara, Japan

Abstract

Phenotypic and genotypic characteristics of five isolates of Cephalotrichum and Sagenomella from various samples collected while dismantling the Takamatsuzuka Tumulus stone chamber were found to represent Cephalotrichum verrucisporum and Sagenomella striatispora. In addition to these, one isolate from the ceiling stone surface in the adjacent small room of the Kitora Tumulus was assignable to Sagenomella griseoviridis. Colonization on biodeteriorated plaster and stone walls as substrata or habitats of these fungi is noteworthy. Physiologically Sagenomella isolates solubilized CaCO₃ and may be involved in the deterioration of the plaster walls inside the stone chamber. Cephalotrichum verrucisporum is a new addition to Japan.
