CONTEXT AND PORES COLORED. 



POLYPORUS VINOSUS (Fig. 679). Pileus thin, usually sessile, 

 dimidiate, dark vinaceous color (dark, livid purple). Surface smooth, 

 concolorous. Context thin, brittle, hard, more brown than the 

 surface. Pores minute, dark, concolorous with the surface. Spores 

 (B) allantoid, 1# x 4-4>^, hyaline. 



This is a frequent species, and widespread in the tropics. We 

 have noted specimens from Cuba, British Honduras, New Guinea, 

 Malay, Java, the Philippines. From the United States, we made one 

 collection in Florida, and at New York Gardens there is one from 

 Harper, Georgia. It has always a thin pileus, usually curling in drying. 

 Generally it is sessile with a broad attachment, but at Kew is a col- 

 lection from West Africa that is petaloid and has a short, lateral stipe. 



SPECIMENS. Java, J. P. Mousset; Ceylon, T. Petch; Congo Beige, Edouard Luja; Mada- 

 gascar, Henri Perrier de la Bathie; Philippines, E. D. Merrill; Japan, A. Yasuda; Florida, C. G. L. 

 The specimen from Congo Beige is much thicker, larger, and has paler context than other collections. 



Compare badius, Mollerianus, tristis. 



POLYPORUS MOLLERIANUS (cfr. Stip. Pol., p. 147) is a petaloid form of 

 Polyporus vinosus, agreeing with the sessile form exactly as to color, context, pores, 

 etc., but spathulate and stipitate. There is a collection at Kew. It is only known 

 from Africa. 



TRAMETES VIOLACEUS. Pileus thin, applanate, rigid, 

 sessile, often decurrent behind. Surface dull, smooth, no distinct crust, 

 pale brown, soft to the touch, minutely velvety. Context firm, hard, 

 slightly punky, pale violaceous color (dull Indian purple). Pores 

 minute, rigid, hard, dark, purple tissue, !-!> mm. long. Spores not 

 found, doubtless hyaline.
