CONTEXT AND PORES COLORED.<br />

tose, ridged. Flesh hard, firm, brown, descending into the pores.<br />

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

Setae, none. Spores abundant, large, elliptical, 8 x 16 mic., deeply<br />

colored.<br />

This is an Australian species, unknown elsewhere though apparently<br />

not rare in Australia. We have seen several collections of it.<br />

It was named by Berkeley, Hexagona decipiens, but it is not a typical<br />

Hexagona as to pores, and is anomalous in having colored spores,<br />

which no true Hexagona has. Its proper classification is as Trametes,<br />

but the same objection, colored spores, holds here. Properly it is a<br />

"new genus" (Phaeotrametes McGinty) on the same principle that<br />

the other similar "new genera," "Phaeocyphella" and "Phaeoradulum,"<br />

were manufactured.<br />

SPECIMENS. Australia, Albert Green, Dr. J. B. Cleland, G. H. Ad cock.<br />

C. Pores small.<br />

POLYPORUS GLOMERATUS. Pileus yellowish brown,<br />

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

inches thick." Surface minutely tomentose, appearing smooth to the<br />

eye. Context thin. Pores greenish yellow, small, angular, 8-10 mm.<br />

long, tissue concolorous. Setae, none found, but imbedded in the pore<br />

tissue are large, deeply colored bodies. Spores abundant, subglobose,<br />

5-6 mic., pale colored, transparent, guttulate.<br />

The above description is partly taken from Peck, who found the<br />

plant on a maple tree and named it forty years ago. Peck was unaware<br />

of the peculiar structure w rhen he named the plant, and attention has<br />

not heretofore been drawn to it. It is a rare plant. Little pieces of<br />

the original collection are at Albany and at Kew, but these were all<br />

that were known until 1914, when Dr. KaurTman made two collections.<br />

It grew on a maple log, resupinate for several feet, also pileate on a<br />

stump. The new pore layers form over the old layers, so that it might<br />

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

annual. From the little specimens preserved, Cooke, Murrill, and<br />

myself have all referred it to Polyporus radiatus or Polyporus nodulosus,<br />

but when we come to examine the structure we find it a very j<br />

different thing. Imbedded in the hyphae tissue are large (12-15 mic.<br />

thick) deeply colored, pointed, seta-like hyphae such as occur in Fomes<br />

pachyphloeus (cfr. figure 600, page 261, Synopsis of Fomes). Peck was<br />

unaware of this peculiar structure when he named the plant, and<br />

attention has not heretofore been drawn to it. We know no other<br />

American plant with this structure. We have similar plants with same ,<br />

peculiar structure from Mexico (Polyporus Rickii).<br />

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

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

Morgan found the plant around Cincinnati, and we have his specimen.<br />
