CONTEXT AND PORES COLORED. 



tose, ridged. Flesh hard, firm, brown, descending into the pores. 

 Pores rigid, trametoid, 4-8 mm. long, round or elongated, large, 1-2 mm. 

 Setae, none. Spores abundant, large, elliptical, 8 x 16 mic., deeply 

 colored. 



This is an Australian species, unknown elsewhere though ap- 

 parently not rare in Australia. We have seen several collections of it. 

 It was named by Berkeley, Hexagona decipiens, but it is not a typical 

 Hexagona as to pores, and is anomalous in having colored spores, 

 which no true Hexagona has. Its proper classification is as Trametes, 

 but the same objection, colored spores, holds here. Properly it is a 

 "new genus" (Phaeotrametes McGinty) on the same principle that 

 the other similar "new genera," "Phaeocyphella" and "Phaeoradu- 

 lum," were manufactured. 



SPECIMENS. Australia, Albert Green, Dr. J. B. Cleland, G. H. Ad cock. 



C. Pores small. 



POLYPORUS GLOMERATUS. Pileus yellowish brown, 

 densely imbricate, "forming a mass >^ foot long and two to three 

 inches thick." Surface minutely tomentose, appearing smooth to the 

 eye. Context thin. Pores greenish yellow, small, angular, 8-10 mm. 

 long, tissue concolorous. Setae, none found, but imbedded in the pore 

 tissue are large, deeply colored bodies. Spores abundant, subglobose, 

 5-6 mic., pale colored, transparent, guttulate. 



The above description is partly taken from Peck, who found the 

 plant on a maple tree and named it forty years ago. Peck was unaware 

 of the peculiar structure w r hen he named the plant, and attention has 

 not heretofore been drawn to it. It is a rare plant. Little pieces of 

 the original collection are at Albany and at Kew, but these were all 

 that were known until 1914, when Dr. KaurTman made two collections. 

 It grew on a maple log, resupinate for several feet, also pileate on a 

 stump. The new pore layers form over the old layers, so that it might 

 be classed as Fomes, but the old layers are dead and we think it an 

 annual. From the little specimens preserved, Cooke, Murrill, and 

 myself have all referred it to Polyporus radiatus or Polyporus nodu- 

 losus, but when we come to examine the structure we find it a very j 

 different thing. Imbedded in the hyphae tissue are large (12-15 mic. 

 thick) deeply colored, pointed, seta-like hyphae such as occur in Fomes 

 pachyphloeus (cfr. figure 600, page 261, Synopsis of Fomes). Peck was 

 unaware of this peculiar structure when he named the plant, and 

 attention has not heretofore been drawn to it. We know no other 

 American plant with this structure. We have similar plants with same , 

 peculiar structure from Mexico (Polyporus Rickii). 



SPECIMENS. A liberal supply from Dr. C. H. Kauffman, Michigan, who is the only one 

 who has collected the plant in recent years. Since above was written, however, we have learned that 

 Morgan found the plant around Cincinnati, and we have his specimen.
