"日本産の肉質キノコ類の消化に関して,ラットに給餌し,糞の検鏡により形態的に観察,不消化物の状態について試験を行った.その結果は次の通りである.1) BasidiomycetesにおいてはTricholomataceae, Amanitaceae, Cortinariaceae, Russulaceae, AscomycetesにおいてはClavariaceaeのFamilyはよく消化されていた.2)BasidiomycetesにおいてはBletaceae, Strobilomycetaceae, AscomycetesにおいてはCantharellaceae, PhylacteriaceaeなどのFamilyに不消化の種類が多い傾向が認められた.3)特に不消化に近い形で排泄されるのを認められたLeccinum scabrum, L. rugosiceps, Strobilomyces floccopus, Boletellus russelliiについて菌傘部,菌柄部にわけて試験した結果,菌傘部に不消化物が多いことを認めた.4)菌傘部の表面と裏面の管孔部にわけて試験したが,管孔部が特に不消化物が多い傾向を認めた.5)管孔部を除いたイグチ科,オニイグチ科は普通の消化のよい肉質キノコと変りがなかった."

"Albino rats were fed the test diet which contained fruit body of Esculent fungus. The feces were observed under microscope about undigested fragments of the fruit body. 1) The fruit bodies of Amanitacese, Cortinariaceae and Russulaceae which belonged to Basidiomycetes and the ones of Clavariariaceae which belonged to Ascomycetes were well digested. 2) Indigestible species were observed mainly Boletaceae and Strobilomycetaceae which belonged to Bacidiomycetes and in Cantharellaceae and Phylacteriaceae which belonged to Ascomycetes. 3) Since the fruit bodies of Leccinum scabrum, L. rugosiceps, Strobilomyces floccopus and Boletellus russellii were excreted as undigested form, further studies were carried out separately about pileus and stalk parts of a fruit body. The result indicated that the pileus part was indigestible. 4) The polyporous part of the back of pileus was indigestible when it was compared with the surface of pileus. 5) When polyporous part was removed, fruit bodies of Boletaceae and Strobilomycetaceae were as digestible as other fungi."
