(when soaked) (Fig. 1987 enlarged) not poroid. Qystidia.none. 
Spores elliptical, 3X6, hyaline, smooth. This is not included in 
Burt's North American species, nor in either Hennings' or Bresadola's 
described South American species (both of which have globose spores) 
or species named by Spegazzini which is not a Merulius. 
TRAMETES SUBMINIMA FROM L. RODWAY, TASMANIA (Fig. 1988).- 
Pileus small, about one cm. pure white, spotting brown, where bruised 
no doubt. Pores at first small, round, becoming large, elongated. 
Qystidia none. Spores not found. 
To the eye very small like Trametes minima (Myc.Notes page 
850 ) a. common little form of Trametes sepium on oak with us. It has 
brown spots where bruised and touched with alkali it turns brown at 
once, a character that Trametes minima, does not have otherwise we 
would so refer it. There is a white Trametes in Japan (Cfr, Myc. 
Notes page 710) that turns red when touched with alkali but that is 
mostly resupinate and differs otherwise. 
IRPEX CASTANEUS FROM PROF. A. YASUDA, JAPAN (Fig. 1989 ).- 
Prof, Yasuda sent this to me with the suggestion that it is the same 
as Merulius castaneus, named and figured in Myc. Notes p. 555. At 
first view it did not seem possible to me, nor will it so impress 
another if our photographs are compared. But on studying them and 
comparing them we believe this is correct although they appear so 
different. I also note two features that are characteristic and com¬ 
mon to them both and which I overlooked on the previous examination. 
First there is a color reaction changing to violet under potash 
solution. Second they have large, hyaline cystidia of the metuloid 
type. Taking everything into account I conclude there is no doubt 
about it now, and the whole story shows what absolute contempt nature 
has for man's ideas of classification. If fungus species were cast 
in molds as the old new-species hunters thought they were, it would 
save a lot of trouble. It would be quite absurd to call the "type" 
specimen an "Irpex" but that is what the species appears to be when 
developed. 
CORDYCEPS DIPTERIGENA (Fig. 1990),- We present a figure of the 
type enlarged sixfold. It came from Ceylon and now consists of two 
clubs from the head (all that remains of the host. ).The Cordyceps 
heads are globose and the stem relatively short. There is at Kew 
(Fig. 1991 natural size) unnamed, but evidently the same species, a 
specimen collected by E. Berkeley at Rangoon. Cordyceps dipterigena. 
appears to be rather frequent and widespread. Moeller found it in 
Brazil, gave a good figure of it and named it Cordyceps muscicola. 
It has never been collected in Europe nor recorded in the United 
States. But I have seen abundant and fine collections in the herbar¬ 
ium of Professor Thaxter at Harvard and Prof. Thaxter told me he had 
collected it several times in our country. 
CORDYCEPS THWAITSII (Fig. 1992 ).- While we are on the fly 
Cordyceps subject, we present (Fig. 1992 enlarged sixfold) of a 
specimen in Berkeley's herbarium which came from Thwaites, Ceylon. 
Berkeley did not name it but it is now pasted on the sheet with 
Cordyceps dipterigena.
