4) Cladonia pseudevansii ASAHINA
According to AHTI (1961), C. pseudevansii ASAHINA occurs in Japanese Archipelago, Sakhalin, Kurile Islands, Aleutian Islands and southern coast of Alaska (cf. Fig. 4).
The range of C. pseudevansii ASAHINA is completely included in the range of C. alpestris RABH. strain-B (psoromic acid +), while the range of C. evansii des ABB., a vicarious species of C. pseudevansii ASAHINA, is excluded from that of strain-B but overlaps with that of strain-A (psoromic acid －) only slightly at the northern limit of its range.
The substratum of C. dseudevansii ASAHINA is the open and exposed ground in alpine regions.
3-a) Addendum to “The genus Oropogon TH. FR.” (Vol. 4, No. 8, p. 129 of this journal)
Recently I received a fertile specimen of O. asiaticus ASAHINA from Dr. S. KUROKAWA collected by himself at Bettoga near Nemuro, Hokkaido (on Quercus sp ; Sept. 1, 1965). This is the northernmost locality of the genus Oropogon.
I happened to get a specimen of O. formosanus ASAHINA collected on Mt. Yuwan-dake in Amami-Oshima, the main island of Amami Island which spread between Kyusyu and Okinawa Island. This is the northernmost locality of O. formosanus ASAHINA which was formerly known only in Formosa and India.
