はじめに
今回の調査研究で秩父山地から確認されたハナビラゴケ属とシコロゴケ属ほそれぞれ6種と2種である：ハナビラゴケ，コフキハナビラゴケ，ヒメハナビラゴケ，コフキヒメハナビラゴケ(Pannaria ahlneriの新称) ，コバノモクズゴケ，テツイロハナビラゴケ，ヤマシコロゴケ，トゲシコロゴケ．これらのうち，本地域からはすでにコフキハナビラゴケ(黒川, 1953 : Pannaria rubiginosa var. lanuginosa ZAHLBR.,ハナビラゴケとして)とヒメハナビラゴケ(KASHIWADANI, 1981)は報告されているが，他の6種は秩父新産として記録される．従って，本報告ではこれらを含めた秩父産8種の検索表とその相違点を簡単に述べる．なお，すでに記録のあるモクズゴケ(黒川, 1953 : Parmeliella leptophylla WAlN.として)は今回の調査では確認されなかったために本報告からは除外してある．

Abstract The lichen genera Pannaria and Parmeliella are known to be members of the Pannariaceae with the genus Erioderma FÉE. They are characterized by the squamulose or foliose thallus, paraplectenchymatous upper cortex, and heteromerous medulla containing Nostoc. These two genera are generally separated by the presence or absence of apothecial margine : Pannaria has apothecia of lecanorine type and Pameliella those of the biatorine type.
YOSHIMURA (1974) reported 9 species of Pannaria and 5 species and one forma of Parmeliellla from Japan. In 1978, JØRGENSEN added two species of Pannaria, P. ahlneri, P. M. JØRG. and P. praetermissa NYL., to the Japanese flora. For the Chichibu Mountains, however, the occurrence of only three species has been confirmed. They are Pannaria rubiginosa (THUNB.) DEL. var. lanuginosa ZAELBR.(=P. conoplea (ACH.) BORY), Parmeliella leptophylla VAIN. (= P. gricea (HUE) KUROK.) (KUROKAWA, 1953) and Pannaria leucosticta (TUCK.) NYL.(KASHIWADANI, 1981). In this paper, 6 species are newly reported from the present area : Pannaria ahlneri, P. rubiginosa, P. lurida, P. leucophaea, Parmeliella incisa, P. nigrocincta f. isidiosa.
