(Vahl) Karsten, Dictyopamis pusillus (Lev), Singer, and Mycena 

 cyanaphos from Bonin Island. Recently Dr. Kobayashi (1951) re- 

 ported the following five luminous species from Miyazaki Pref. of 

 South Kyushu, Japan: Poromyceiia Hanedai Kobayashi, Dictyopamis 

 foliicohis Kobayashi, Mycena pseudostylobates Kobayashi, Mycena 

 daisJiogunemis Kobayashi, and Mycena sp. 



Lanipteromyces japonicus is a large luminous fungus which grows 

 on the dead trunks of beech trees in autumn. It is famous for the 

 Japanese name Tsukiyo-ddke, meaning "moon night mushroom." It 

 is a poisonous species and closely resembles the nonluminous and 

 edible species Pleurotus ostreatus. According to Dr. S. Kawamura 

 (1915), the luminescence comes only from the lamellae of the fruit- 

 body, and not from the spores. However, according to my observa- 

 tions, spores fallen upon moist blotting paper are slightly luminous. 

 Polypoms Hanedai Kawamura (1940) is the synonym of Poromycena 

 Hanedai. I found it in a jungle near Tawao, North Borneo, in March 

 1938. In August, 1953, Mr. Okuyama collected this fungus which 

 had grown on decayed trunks of mulberry trees at Hachijo Island. 

 Three other luminous species were found by us on Hachijo Island: 

 Mycena chlorophos, Dictyopamis gloeocyst Corner, and Mycena lux- 

 coeli Corner. The last mentioned species, illustrated in Fig. 1, is very 

 common. 



Tropical Luminous Fungi 



Recently Dr. Corner has identified specimens of luminous fungi 

 from the tropics and from Hachijo Island. According to him, seven 

 Mycena, two Poromycena, two Dictyopamis and one Pleurotus were 

 identified as Mycena chlorophos (B. & C.) (Palao, 1937; Celebes, 

 1943; Hachijo Island, 1952), Mycena rorida sp. nov. (Singapore, 

 1944), Mycena pruinvsoviscida sp. nov. var. rahaulensis var. nov. 

 (Rabaul, 1942), Mycena lux-coeli sp. nov. (Hachijo Island, 1951), 

 Mycena suhlucens sp. nov. (Amboina, 1942), Mycena noctilucens 

 Kawam (Yap, 1937), Mycena illuminans Henn (Singapore, 1944), 

 Poromycena Hanedai Kobayashi (Borneo, 1938; Rabaul, 1942; Miya- 

 zaki, 1951; Hachijo Island, 1952), Poromycena manipularis sp. nov. 

 (Ponape, 1940), Dictyopamis luminescens sp. nov. (Singapore, 1944), 

 Dictyopanus gloeocyst sp. nov. (Hachijo Island, 1951), illustrated in
