海洋深海掘削（ODP）Leg-200の玄武岩中の割れ目を充たすcalcite中に見つかった fungi（キノコの類，菌類）と推定されるフィラメント状組織（口絵2参照）


Filament Shaped Fungi-like Structures Surrounded by Calcite in Basalt Sheet Flow Obtained by ODP Leg 200 Site 1224F

海洋底深海掘削（ODP）のLeg-200の際，1224掘削地点における海底下深さ51mの玄武岩中の割れ目（空隙）を充たすcalcite中から得られた化石化した菌類（fungi）と考えられる組織の写真．菌類の菌糸（hypae）フィラメント組織が左上の玄武岩組織から右下方の内部へ伸びている．これらの菌糸の断面の寸法は約5-10μmであり，菌糸の長さは50μm から数100μmである．スケールは 10μm．．
