Abstract A lectotype is selected for Cetraria kurokawae from the paratypes since the holotype ismissing from the herbarium of the Department of Botany, National Museum of Nature and Science(TNS) for a long time.
Key words : lichenized Ascomycota, Nephromopsis, nomenclature, Parmeliaceae, taxonomy, typiﬁcation, Usnocetraria.

Cetraria kurokawae Shibuichi & K. Yoshida
was originally described based on specimens collected from Chichibu Mountains in Saitama Prefecture and Omogo Gorge in Ehime Prefecture in
Japan (Shibuichi and Yoshida, 1982). This species is currently treated as Usnocetraria kurokawae (Shibuichi & K. Yoshida) M. J. Lai &J. C. Wei (Parmeliaceae, lichenized Ascomycota),
an endemic and rare lichen species in Japan. It ischaracterized by the yellowish green thallus withisidia (Fig. 1) and the presence of usnic, alectoronic, fumarprotocetraric, and succinprotocetraric acids as the major chemical substances(Shibuichi and Yoshida, 1982; Lai et al., 2007).
A specimen collected on bark of Chamaecyparis obtusa in Mt. Mitsumine, Chichibu-gun,Prov. Musashi, Honshu, Japan (S. Kurokawa
64315) was designated as holotype. However,
the holotype specimen is missing from the herbarium packet for long years in the herbarium ofNational Museum of Nature and Science (TNS).
Therefore, we designate a lectotype for C. kurokawae according to ICN Art. 9.2 (MelbourneCode). It has been selected from the paratype
specimens that coincide in morphology andchemistry with the protologue (cf. ICN Art.
9.12).
