Abstract
Recently, cases of deep-seated mycoses caused by basidiomycetes, such as Schizophyllum
commune , have become widely recognized. However, there are few reports on the distribution
of airborne basidiomycetes in the living environment, and their dissemination patterns have
not been elucidated. Therefore, we conducted a sampling survey of airborne basidiomycetes
from April to June 2017 in a residential house in and around three children's public parks. As
a result of this survey, white filamentous fungi, including basidiomycetes, were isolated from
the investigation sites throughout three months. The 27 white fungi isolated in the survey
were identified by the gene sequence analysis of the ITS region. Of these, 26 strains belonged
to the phylum Basidiomyceta, and they were classified into 8 species. The identified 10 strains
were the most common strains of Trametes hirsuta , and 5 strains were, a known pathogenic
basidiomycetes, S. commune. More than half of the strains of T. hirsuta were isolated in June,
suggesting that its distribution might be seasonal. The results of this survey revealed that
basidiomycetes, known to be responsible for allergic bronchopulmonary mycosis, were normally
distributed in residential house and in childrenʼs public parks that were in the vicinity.
