Pores minute, round, with white mouths. Spores globose, strongly 

 rough, reticulate, 10 mic. 



We were at first disposed to refer this to Polyporus subrenatus, 

 named from a single specimen from British Honduras which has the 

 same spores. On a recent visit to New York we compared them and 

 they are not possibly the same. The leading features, however, the 

 dull, non-laccate surface, the pale context, and particularly the globose, 

 reticulate, strongly rough spores which are exceptional in this group of 

 plants, are the same. These peculiar spores only found in one other 

 related species, are not mentioned in the original "description" 

 of Polyporus subrenatus. Both species belong in Section 6a (Amau- 

 rodermus) of our Stipitate Polyporoids. 



POLYPORUS (CAN.) DORSALIS, FROM REV. J. RICK, 

 BRAZIL (Fig. 939). This corresponds to Pol. lucidus, excepting 

 in the stipe insertion which is dorsally attached. Pol. lucidus never 

 has a stipe attachment like this. As lucidus, it is a "light weight" 

 species. Polyporus fornicatus has the same shape and attachment 

 exactly (cfr. Stip. Pol. fig. 398), but is a "heavy" species, that is, it 

 has minute, heavy, hard pores, and belongs to a section corresponding 

 to "Ponderosus" in our Fomes pamphlet (section 74, page 269). 

 On form alone, both are same, but in nature of pores they are quite 

 different. The stipe is much longer than our figure, which is taken 

 to show the stipe attachment. 



While our figure of Polyporus dorsalis (939) has a close resem- 

 blance to the figure of Polyporus infulgens (938), they are quite 

 different plants. Polyporus dorsalis belongs to Section Ganodermus 

 with strong laccate surface and truncated spores. Polyporus in- 

 fulgens belongs to Section Amaurodermus with dull surface and 

 globose spores. Polyporus dorsalis is probably best held as a form of 

 Polyporus lucidus, but I believe the stipe attachment is of more im- 

 portance than most characters on which species are based. 



GUEPINIA PEZIZAEFORMIS, FROM J. B. CLELAND, 

 AUSTRALIA (Figs. 940 to 942). We are very much pleased to 

 receive this little species from Dr. Cleland. It is the first we have 



Fig. 940. Fig 94 i 



gotten It is scantily represented at Kew, also a collection from 

 Australia at Berlin. It is not known from any other country. Gue- 

 pima pezizaeformis is not well named, for it is not pezizaeform. 

 Ine dried specimens curl up and Berkeley may have carelessly taken 

 them for little cups, but they are not. They are about same form
