Mycological field works in Mizugami natural forest

Mizugami, Nakaheji, Mishimuro, Wakayama 2003.10.19

Mizugami natural forest (or Taya research forest, a private property), Nakaheji town (formerly Kurisugawa village, north-east of Tanabe), was one of Kumagusu's frequently visited research fields since 1908. This forest is said to keep until now the primeval laurel forest scenery of South Kii of pre-human day. When the participants arrived 'to observe the mushrooms and slime molds in Kumagusu's favorite forest', Mr Gotoh Takeshi and his two sons had just turned up there as well. This casual encounter suggests how few the laurel forests have become which still keep their original biological diversity today.

Professor Hagiwara showed exemplarily how to treat a collected specimen. Taken a set of paper box kit out of his shoulder bag, cut the bark on which a slime mold grows with the folded knife hung under the belt, and then glued it to the bottom of the paper box. A knife folder is seen on Prof Hagiwara's right waist, and a viewing glass (loupe) with a red strap around his neck. [TY]

A slime mold on the bark was glued to a paper box. Unused paper box kits are also seen. Camera could not follow quick procedures of Prof Hagiwara. A god's hand, really... [TY]

Imperfect fungus growing on a slime mold Fungus imperfectus super myxomycete

Prof Hagiwara found a kind of imperfect fungi with his viewing glass, and told the participants on a type of imperfect fungus which grows only on a specific kind of slime molds.

Comment of the picture-taker [Tanaka]: Hagiwara sensei urged me to 'eat and experience its bitter taste', and it was true. Later, however, I consulted with a reference book and found that

Causes stomachache, vomit, shiver or diarrhea within half an hour to three after ingestion. In worse cases, dehydration, acidosis, convulsion, shock, and even death may be resulted. (from: "Japanese toxic fungi")

... Hagiwara sensei, you knew everything, and made me have one!

Insects Insectae

[Photo: Geotrupides 1] [Photo: Geotrupides 2]

A large beautiful scarab Geotrupides auratus (perhaps what Kumagusu called 'Senchi mushi', or 'toilet bug'). On this day, we saw this species here as well as in Nishinoko preserved forest. This beetle eats dung of the mammals, and probably that is why it spontaneously comes close to human being. [TY]

When you walk along in the woods, this bug flies to the smell of your sweat. (...) This bug can live in the woods in which large mammals dwell abundantly. ("Kumano Nakaheji: the Nature of Ohtoh mountains" - 'Kumano Library 5', p 90).

Higher plants Herbae

Mikaeriso spike Leucosceptrum stellipilum. Latin taxonomical name means 'a bright sceptre with starry hair'. Japanese name 'mikaeri-so' is also said, as Mr Gotoh told us, to have derived from its beauty so as to '(let you unconcsciously) look back'. He added, however, 'though I myself don't find it so beautiful'. [TY]
