POLYSTICTUS DYBOWSKI (Fig. 354>.-With the same nature color 

 pores, and partial range, but with much finer hairs on the pileus I should con- 

 sider it as a form of Polystictus leonmus. It came from Africa but w- s not 

 named for one of the natives as might be inferred from its name.

 Polystictus Dybowski. 



POLYSTICTUS STUPEUS (Fig. 355). Pileus rather thin, 

 with a dense coat of branching hairs. Pores large, regular, with thin 

 walls. Mouths even. Color of entire plant, including hairs, "fauve." 



This is an American species with a curious history. It is rare in America 

 and I have never received it from a correspondent. I know of but four col- 

 lections, all at Kew. Berkeley found a small, unsatisfactory specimen in the 

 Richardson collection from British America which he named Trametes stupeus 

 and gave the locality "Carleton House, British Columbia, Apr. j.^rd." And 

 it is a curious coincidence that there is another collection at Kew made by 

 Palliser, who collected in British America, and is endorsed "Sur les vieux 

 troncs de Salix pres Carleton, 18 Mai, 1858." This was referred to Trametes 

 gallica 1 '"' but is the same as Polystictus stupeus, and apparently from the same 

 locality though some ten years after it was named. Then Berkeley ot it 

 from Texas, Wright, and called it Trametes Lindheinieri." 1 This collection 

 has smaller pores than the Canadian plant but otherwise seems close. In Cooke's 

 herbarium is a collection, 'Tndia, Herb. Griffith" that seems exactly the -;iinc 

 as the Canadian plant. 



13 "Trametes gallica" was based on an old French figure, more than a hundred years old, 

 and has never been recognized in France to this day with certainty. In his forty years' ex- 

 perience Botidier tells me he thinks he has seen it twice. The improbability of its being found 

 in British America I presume never appealed to the man who so referred this collection. 



10 A good type specimen is at Kew, in good condition, not eaten at all by insects, as has 

 been misstated, and our figure 355 is made from it.
