SECTION AMAURODERMl'S. 



line, as is the context. Spores (only conidial, I think) globose, C ,,], 1U .I 

 strongly tubercular, rough, 8 mic. A remarkable species known from 

 one specimen at Kew collected by Spruce in Urazil. It is the lariat 

 mesopodal polyporoid I have noted and grew on w, ><!. I suspect that 

 its normal spores would be found to be quite different, and that the 

 plant is not well classed in this section. No other plant in this section, 

 I believe, grows on wood, and most of them have subterranean 

 rhizomes. 



b. STIPE WITH A SMOOTH, LACCATK CRUST. 



LEPTOPUS. Pileus 5 cm. broad, i l /> cm. thick, with a dark, 

 smooth crust. Stem, almost gone now, but enough remains to show 

 that it was mesopodal, about 12 cm. long, one cm. thick, and had a 

 dark, smooth, shiny, laccate crust. Context pale cinnamon. Pores 

 small, about one cm. long, pale cinnamon. Spores globose, 12 mic., 

 strongly rough. The species was referred by Fries, who never saw it, 

 to umbraculus, of which no type exists, and I think there are no grounds 

 for accepting the reference. It was so accepted by Patouillard, now- 

 ever, who drew his characters from Persoon's specimens and knew 

 nothing whatever about Fries' plant. The species is only known from 

 the original, Persoonian specimen, preserved at Paris. It was from 

 the island of Rawak. 



LONGIPES (Fig. 411). Pileus unilateral, attached, with a red- 

 dish brown crust which is not polished (laccate) as the stipe. Stipe 

 slender, with a black, shiny, laccate crust. Pores large, pale cinnamon, 

 reaching the crust. Spores unique, globose, 12-14 mic., strongly rough, 

 having the asperities arranged in distinct bands or areas. This is a 

 very peculiar species, known only from one quite abundant collection 

 from French Guiana. Collector unknown. Leprieur, who made large 

 collections from the same locality, never found it. 



RENIDEXS. Pileus dull reddish brown. Stipe lateral, smooth, 

 laccate crust. Context scanty, cinnamon. Pores and pore mouths 

 concolorous. Spores globose, 8-9, rough. Known to me only from 

 the type at Berlin, from Brazil, collected by Moeller. (Plants dis- 

 tributed by Rick as formosissimus are said to be the same. I have 

 not examined their spores.) Except as to the spores this species has 

 the general appearance and character of Polyporus lucidus. 



BASILAPIDOIDES (as Laccocephalum). Pileus brownish fawn, with 

 strongly pitted surface. Context whitish. Stem short, thick, mesopodal, fo 

 at the base a large, hard, false sclerotium, consisting of agglutinated grains of 

 sand fixed by the mycelium. Spores globose, orange yellow, echinulate, ' 44-50 

 in." (mic.?) in diameter. This Australian species, called the "stone making 

 fungus," is only known in Europe from the description and figures in an Aus- 

 tralian publication. It was proposed as a "new genus, but I 

 spore characters it should be classed here.
