摘要
A new pleomorphic ascomycete, Calyptrozyma arxii, isolated from the human lower oesophagus, is described. Initial growth results in yeast cells, followed by formation of hyphae. Asexual reproduction occurs by blasto-, aleurio- and arthroconidia In addition, unicellular to multicellular conidia-like cells occur, which initially are somewhat thick-walled. Finally, the outer wall layers of these cells become loose. Sexual reproduction is by eight-spored asci formed on aggregations of generative hyphae. Although no ascomata are formed, the fungus belongs to the Euascomycetes, as was deduced from septal ultrastructure and partial ribosomal RNA sequences.
