ably not this species, which is thick, fleshy, and has obtuse gills. 

 I never looked up the type. The two American species by Schweinitz, 

 one, C. viridis is unknown from any specimen, and from description is 

 probably not a Cantharellus; the other, C. olivaceus, is a Paxillus. 

 The last species in Saccardo Cantharellus ramealis, from Java, is a 

 Guepinia. In addition, there is a species of pleuropodial Cantharellus, 

 which has been named as Craterellus as follows: 



CANTHARELLUS PARTITUS. This is a thin, small plant about a cm. 

 growing on wood. It is only known from an old type, at Kew from " New Ireland." 

 It is black now, probably discolored in drying. I believe it to be misnamed "par- 

 titus " for it is not parted. It has never been recognized since named and probably 

 never will be. 



"TREMELLA" MYCETOPHILA, FROM S. H. BURNHAM, 



NEW YORK (Fig. 950). This is really a fungus without a name. 



It is not rare, always found on Collybia 



dryophila. Peck called it Tremella my- 



cetophila, but it is only a Tremella in gen- 



eral resemblance. The texture is not tre- 



mellose and it has the ordinary clavate 



basidia in both characters entirely foreign 



v^ to a Tremella. Burt in 1901 proposed to 



<JB put it in the genus Exobasidium, although 



9L about as different from the other species 



J ^^k , of Exobasidium as it is from a Tremella. 



J ^M In his latest writings Burt excludes it from 



S ^^L Exobasidium as he now considers it "a 



^^P teratological production of Collybia dry- 



^HL ophila induced by protracted wet weather 



^La during development of the frutification." 



Hence he leaves it without a name at all. 



We do not claim to know anything about 



j^f j what it really is. We only know it is not 



Fig. 95o. r are in this country and that it does not 



occur in Europe, and that Collybia dry- 



ophila as well as "wet weather" are both common in Europe. It 

 looks like the same conditions would produce the same efiect on the 

 same plant in both countries. 



Daisy M. Hone had an extended article on this plant in 1909. 

 She found it forming large masses on the pileus and stems of the 

 Collybia. She considers it "a true parasite." If Burt's theory is 

 correct, it is an exceptional case. We have sometimes noted evident 

 teratological development of Agarics forming abortive pilei on top of 

 the normal pileus like the celebrated Poria agaricicola that a German 

 savant discovered on Amanita (cfr. Myc. Notes, page 459). But we 

 think there is no other case where an Agaric habitually develops an 

 entirely different and constant fruiting form, in addition to the 

 normal gills.
