Onifusube - Onifusube

Japanese: オニフスベ - おにふすべ
Onifusube - Onifusube

A mushroom of the Basidiomycete and Gastromycete families, Pungenthumaceae. It is a huge, spherical mushroom, measuring 20-40 cm in diameter. At first, it is covered with a white, leather-like outer skin, but later it turns dirty brown and dries, releasing a large amount of moisture with a strong odor. Even if it weighs more than 10 kg at first, it weighs less than 1/20 of that when it dries. As it dries, the outer skin breaks and then peels off, exposing the inside, which is covered in a dirty brown thin skin. The flesh inside is white and puffy at first, but when it matures and loses water, it becomes dirty brown and dusty like old cotton. The dusty powder is the spore, which is spherical and 6-8 micrometers in diameter, and has many thorn-like protrusions on its surface. It is also called Yabudama, as it often grows in bamboo forests from July to October. It is edible when young. For a long time, its scientific name was placed in the genus Lasiosphaera . The giant puff ball ( Calvatia maxima (Schaeff.) Morgan) found in Europe and the United States is a separate genus and species.

Japanese:

担子菌類、腹菌類ホコリタケ科のキノコ。径が20~40センチメートルにもなる巨大な球形のキノコ。初めは白いなめし革に似た手触りのする外皮で覆われるが、のち汚褐色になり、強い臭気をもつ水分を多量に出して乾いてくる。初めは重さ10キログラム以上ある場合でも、乾けば20分の1以下の重量になる。乾くにつれて外皮は破れ、さらにはがれて、汚褐色の薄皮に包まれた内部を露出する。内部の肉は、初め白いはんぺん質だが、成熟して水を失うと汚褐色のほこりだらけの古綿状になる。ほこり状の粉は胞子で、これは径6~8マイクロメートルの球形であり、表面には多くの刺(とげ)状の突起をもつ。7月から10月にかけて、よく竹林に生えるので、ヤブダマともよばれる。若いときは食用になる。学名は長い間Lasiosphaera属に置かれた。なお、欧米に産するgiant puff ball/Calvatia maxima(Schaeff.)Morganは別属別種である。
