SECTION PELLOPORUS. 



37. PELLOPORUS POLYSTICTUS. CONTEXT THIN, 

 FLEXIBLE. 



Small plants growing in the ground with mesopodal stems. This is the old section Perennes of Fries. 



a. COLOR DULL CINNAMON. 



PERENNIS.- The most frequent species of the section in both 

 Europe and the United States. Known from its dull, zonate, cinna- 

 mon color. Pores small. Spores 4-5 x 8-10, pale colored. 



FOCICOLA. Very similar to the preceding species but with 

 larger pores (i mm. or more). Frequent in the southern United States 

 and there replaces the perennis of the northern states. Unknown from 

 Europe. 



DECURRENS. A rare plant if not a form, based on one collection, from 

 Massachusetts (Cfr. Pol. Issue, p. 12). 



PICTUS. It is a little, slender species known only from specimen in the 

 Herbarium of Fries. It has very thin context, }/> mm., pores 2 mm. long, and 

 the color now is black. Distinct but rare. Spores 6x8. The reference Bulliard 

 No. 254 is an error as also are the French records of this plant. 



b. COLOR BRIGHT, FERRUGINOUS CINNAMON. 

 CINNAMOMEUS. A uniformly bright colored plant with silky, 

 shining, appressed, radiating fibrils. Very rare in Europe, more fre- 

 quent in the United States. Pores small. Spores 5-6x7-10, pale 

 colored under the microscope. The forms from Ceylon and India are 

 otherwise the same but have more globose spores, 6-7 x 8. 



OBLECTANS. The Australian plant (and it is evidently very common 

 in Australia) differs from the European in having usually larger pores and 

 more erect fibrils on the pileus. Spores are 5x8, pale. The color is the same 

 and the plants have been held to be the same, but I feel that the Australian 

 plant is entitled to a name. 



OBLECTABILIS (Fig. 464). This, which is based on speci- 

 mens collected in Brazil, distributed by Ule (No. 48) has been referred 

 to oblectans of Australia. It is similar in color but is more slender, 

 has larger, more shallow pores. The margin is thin and fimbriate 

 and the spores more narrow and more pointed. The spores are 4 x 10, 

 pale colored and tapering at one end. 



OBLIVIONIS (Fig. 465). Entire plant unicolor, of a bright 

 cinnamon color. Pileus soft, subzonate, appressed, fibrillose. Con- 

 text thin, less than i mm. Pores minute, 2 mm. deep. Stipe slender, 

 3-4 mm. thick, soft tomentose, 7 to 10 cm. long. Spores abundant, 

 elliptical, 7-8 x 10-12 mic., colored. This is a beautiful species known 

 from one collection at Kew from Brazil. It is much larger than any 

 other brightly colored species of this section.
