from description, and perhaps they are the same species. As all 

 these yellow Guepinias on pine are rare plants, we are particularly 

 glad to get this nice collection from Mr. Grant. 



As to basidia and spores, Guepinia is same as Dacryomyces, and 

 the reason this is not a Dacryomyces is that the hymenium covers 

 one face only. Still the distinction in some specias of Dacryomyces 

 is not marked, and these obconic Guepinias are perhaps better called 

 Dacryomyces. Our figure (849) is a specimen soaked out and en- 

 larged six diameters. 



POLYPORUS ROSETTUS, FROM MRS. A. V. KIRKWOOD, 

 AUSTRALIA (Fig. 850). Submerismatoid. Proceeding frorn a hard, 

 woody base, it divides above into a number of short, irregular lobes. 



Fig. 850. 

 Polyporus rosettus. (Showing top and section.) 



Pores small, round, irregular, white. Context very hard, white. 

 Surface fuliginous. Spoies 3x5, hyaline, piriform. 



The method of development is unlike any other species known 

 to me. It is not a true Merismus, but we would place it for convenience 

 in that section. The feature of the species is the hard, woody context 

 similar to Polyporus Spraguei and Polyporus ostreiformis and Poly- 

 porus osseus in texture. We have gotten it before from W. W. Froggatt, 

 Sydney (No. 7), and Dr. J. B. Cleland (No. 71). 



IRPEX NOHARAE, FROM K. MIYABE, JAPAN (Fig. 

 851). This species named from Japan, we have from Mr. Miyabe for
