1. Calostoma japonicum H_<ENN>, which is very commonly found in Japan, is very near C. ravenelii (B_<ERK>.) M_<ASSEE>. They are, however, separated as follows. C. japonicum : Rooting stem shorter than the head or hardly exceeding the double length of it, narrower than the latter; exoperidium gelatinous in wet stage; endoperidium clay-coloured; spores oblong with somewhat larger and irregular pits. C. ravenelii: Rooting stem 3-5 times longer and commonly broader than head; exoperidium not gelatinous ; endoperidium clay to brown coloured ; spores oblong, mingled with globose one, with minute pits. 2. L_<LOYD>, Y_<ASUDA> and others have enumerated the same Japanese fungus in the name of C. ravenelii. The true C. ravenelii has not yet been found in Japan. 3. Dr. H. H_<ARA> collected two specimens of Calostoma in Bakkim (ca. 3000 m) of Sikkim-Himalaya during the Japanese Botanical Expedition (1960). This is surely C. junghuhnii (S_<CHLECHT>. et M_<UELL>.) M_<ASSEE> as already been reported by B_<ERKELAY> from Himalaya basing on the H_<OOKER>'s collection. 4. Calostoma formosanum (S_<AWADA>), which was found in Formosa, seems to be a form of C. junghuhnii with very short rooting stem.
