カンゾウタケ
スダジイの木にカンゾウタケが生えていました。シイなどのブナ科の樹木に生えるキノコのなかまです。和名は、色や形が肝臓に見えることに由来します。また、世界各地で見られるキノコで、フランスでは見た目から牛の舌と呼ばれているようです。
"Kanzou-Take" mushrooms are growing on a "Sudajii" tree. They typically grow on trees of the beech family, such as chinquapins. Their Japanese name, "Kanzo", which means liver, comes from their liver-like appearance. These mushrooms are also found in Europe and North America. In French, they are called "Langue de boeuf", which means ‘cow’s tongue’, a name that likewise refers to their shape.

ツバキの木の根元にツバキキンカクチャワンタケが発生していました。春にツバキの花が咲くころ発生するキノコの仲間です。胞子は近くに落ちたツバキの花の上で発芽し、花を分解して生長します。その後、菌核を作り冬を越して、翌春のツバキの花が咲くころにまたキノコを作ります。
