Dictyonema morrei (Nyl.) Henss.

Japanese: フランネルゴケ（英語表記）Dictyonema morrei (Nyl.) Henss.

A basidiomycete lichen of the Dictyonema family that grows in warm regions south of the Kanto region. It lives symbiotically with the blue-green alga Scytonema to produce deep green, fuzzy lichen bodies that spread over rocks and mosses, but do not form obvious lobes. It forms a white fruiting layer on the underside of the lichen bodies and produces basidiospores. There are two species of the Dictyonema genus known to be native to Japan, and D. sericeum (Sv.) Berk. looks like a blanket laid out in a semicircle. [Kashiwatani Hiroyuki]

関東以南の暖地に生えるケットゴケ科の担子地衣類。ラン藻類のスキトネマ属Scytonemaと共生して，深緑色のけば立った地衣体をつくり，岩上や蘚類上に広がるが，明らかな裂片は形成しない。地衣体の裏に白色の子実層を形成し，担子胞子をつくる。ケットゴケ属Dictyonemaは日本産2種が知られ，ケットゴケD.sericeum (Sv.) Berk.は毛布を半円形に敷き並べたような外観をもつ。【柏谷博之】
