STEREUM CAPERATUM, FROM MISS A. V. DUTHIE, 

 SOUTH AFRICA (Fig. 751). Effuso-reflexed, largely resupinate, 

 but with well developed, pileate portion. Surface tawny with puffed 

 margin, matted, tomentose. Hymenium white. Metuloids (typical) 



Fig. 751 



sharp, hyaline, rough, abundant, projecting 30 mic., but borne at 

 various levels, and many of them entirely imbedded. Spores ellip- 

 tical, 5x8, hyaline, smooth. 



Closely related to Stereum bicolor, it is a Lloydella for those 

 who recognize this genus. These are the only two species with white 

 hymenium known to me. 



PTYCHOGASTER ALVEOLATUS (Fig. 752), 



FROM FRANK H. AMES, NEW 



YORK. Supposed to be the coni- 



dial deformation of Polyporus rufes- 



cens, named as above by Boudier. 



The specimens are globose, not 



elongated, as shown in Boudier's 



figure, but in malformations, shape 



does not count for much. An 

 account of the "genus" Ptychogaster was given 

 in Mycological Notes (Pol. Issue), page 31. 

 Ptychogaster appears in Saccardo as Ceriomy- 

 ces, which is a juggle that would have done 

 credit to our New York friends. 



POLYPORUS DISTORTUS (Fig. 753), 

 FROM FRANK H. AMES, NEW YORK, 

 or the abortive form of Polyporus rufescens 

 of Persoon. This specimen, however, is of a 

 very peculiar, narrow, pointed shape, exactly 

 the same as to shape as Boudier illustrated 

 under the name Ptychogaster alveolatus, which 

 is, as he states, a Ptychogaster form of Poly- Fig. 753.
