Orthothecium intricatum (HARTM.) B. S. G. is reported for the first time from Japan. Two collections were made on moist calcareous soil at the Unkai limestone cave, Chichibu, Saitama Pref., Japan. One collection has some leaves with margins weakly recurved on part of the leaf, but the slightly secund and narrow, long-acuminate leaves suggest an identity with O. intricatum. Similar variation is also found in the European collections.

  The occurrence of two rare lichens in Japan is reported in this paper. Both specimens are preserved in the herbarium of the Biological Laboratory of the Imperial Household, with duplicates in TNS. Cladonia delicata has previously been known only from three localities in Japan and this is the fourth record. Usnea bismolliuscula subsp. pseudomolliuscula ASAH. appears to be extremely rare. It was previously known only from the type locality at Hakone, Prov. Sagami. This is the second record for the subspecies.
