SPORES COLORED. 



POLYPORLS RICKII. Recently named from Brazil, is an abnormal Ptychogaster form of 

 some species similar to Polyporus glomeratus. : It has abundant, colored, conidial spores, all sizes 

 and shapes. Ptychogaster Cubensis is suggested as being the same thing. I hardly feel that the sub- 

 ject is much cleared up by the publication of such species.

Polyporus nilgheriensis. 



POLYPORUS NILGHERIENSIS (Fig. 691). Pileus thin, 

 dimidiate, dark argus brown. Surface with dark brown, subzonate 

 velumen. Context thin, concolorous. Pores minute, round, 2-3 -mm. 

 long, with concolorous tissue and dark mouths. Setae, none. Spores 

 globose, 4 mic., pale colored. 



Polyporus nilgheriensis has been referred to as a Fomes. While 

 the pores have a layer effect, we believe this is due to a union of con- 

 fluent pilei and that the plant is better classed as a lignescent Poly- 

 porus. It is a very distinct species only known from a few collections 

 from India, and named originally by Montagne. It has been most 

 badly confused, and in the cover before me are 29 specimens so named, 

 only one, the cotype, having any resemblance or relation whatever 

 to it. There was a cotype in Hooker's herbarium, which Berkeley for 

 some reason evidently thought was wrong, for he marked it "non," 

 and so determined another species from India in Hooker's herbarium. 

 He passed the mistake on to Fries, who enlarged on it by so referring 

 Polystictus pergamenus from Mexico. Then Patouillard fell into the 

 trap, but Murrill escaped, by what fortunate chance we are unable 

 to surmise. Polyporus nilgheriensis is given in Saccardo as growing 

 in India, Carolina, United States, British America, Cuba, and Central 

 America, all wrong excepting the first. 



Compare Garckeanus.
