noun
bolete
Refers to mushrooms of the bolete family, typically with pores instead of gills. In everyday Japanese, イグチ is the most common written form.
秋になると、山でイグチがたくさん採れる。
In autumn, you can pick lots of boletes in the mountains.
The origin is uncertain. The kanji 猪口 (literally 'boar mouth') is ateji and does not reflect the meaning.
