have the genus in its real character. The "setae" which Cooke shows 

 as rigid, sharp, colored spines are in reality obtuse, colored bodies 

 imbedded in the thin, gelatinous outer layer so that they appear on 

 the surface, but have no resemblance, however .remote, to Cooke's 

 figure. The basidia are typically those of an Exidia as shown by 

 Brefeld, and well known, with no resemblance to the clavate basidia 

 of Cooke's figure, which no true tremellaceous plants have. The 

 spores are elliptical, 6x12, -pale yellow tint, and similar to Exidia 

 spores. There are species of Dacryomyces with as deeply colored 

 spores, and there was no basis for a genus on the color of spores. 

 Cooke represented them as "bright brown," which I have always 

 thought was a bull, for no tremellaceous plant is known with deeply 

 colored spores. The spores that Cooke described and figured are 

 found on the specimen at Kew, but they are accidental, probably 

 from some Coniophora, as I suspected when I saw them, and of which 

 I am now assured. 



PORIA XYLINA, FROM A. YASUDA, JAPAN (Fig. 895). 

 Pure white, soft cottony, with broad, soft margin. Tissue of hyaline, 

 loosely woven hyphae. Pores large, angular, oblique. Cystidia none. 



Spores abundant, ellip- 

 tical, 6x8, transparent 

 hyaline, with a large 

 gutta. 



This is not a Euro- 

 pean nor an American 

 species, and probably 

 not named. The speci- 

 men is resupinate, hence 

 a Poria, but it has a 

 nodular effect, as though 

 it might develop a pileus, 

 in which case it would 

 be a Polyporus. It is 

 too soft for a Trametes. 



PORIA SUBICU- 

 LOSA. FROM MR. C. 

 J. HUMPHREYS, 

 WISCONSIN (Fig. 

 896). We present a 

 photograph as it is a rare 

 species. Heretofore it 

 Fig. 895. has been collected but 



, . , once by Peck in 1879 



and does not occur in Europe. It belongs to the ferruginous section 

 and is characterized by its large pores, soft, loosely adnate subiculum. 

 i ne plant has no setae and spores are globose, hyaline 5-6 mic. 

 'fessor Humphrey found it on very rotten hemlock
