XYLARIA RADICANS, FROM P. HYAT VANDERYST, 

 CONGO, BELGE (Fig. 1080). Clubs ii l A cm. long by 4-5 mm. 

 thick, obtuse, all fertile, sessile, or rather there 

 is no distinct stipe from the rooting base. 

 Rooting base 2-3 cm. long, 3 mm. thick. 

 Surface even, greyish black, the perithecia 

 protruding but little. Spores 5 x 12. This 

 species evidently grew in the ground, the 

 clubs on the surface. The rooting bases are 

 all broken and they were probably attached 

 to a buried stick. I have no notes of any 

 species with this habit, excepting Xylaria 

 radicata (bis) which, with its rooting base 

 "a cm. thick," this can not be. There is an 

 African species that I do not know, except- 

 ing from accounts that it has the habit of 

 growing from buried sclerotia formed in termite nests. It is repre- 

 sented as having a long, uniform, cylindrical club. Perhaps this is a 

 variation of that species (Xylaria nigripes). 



XYLARIA ALBOMACULATA, FROM M. R. ESPINOSA, 

 CHILE (Fig. 1081). Clubs slender, strongly rugulose with the pro- 

 truding perithecia, spotted with little white discs (over the mouths of 

 the perithecia?). Fertile portion 2-3 cm. long, 2 mm. thick, some- 

 times tipped with a slender, sterile apex of equal length. Stroma

white, scanty. Stipe filiform, smooth, 1-2 cm. long. Perithecia only 

 partially imbedded. Spores 7 x 14. This reminds one very closely 

 of Xylaria scopiformis (Cfr. Myc. Notes, p 675), but it is characterized 

 by the white discs which appear to be around the mouths of the 

 perithecia. Other species have similar white discs (Cfr. Xylaria 

 Guyanensis Myc. Notes, p. 649). We present a figure of the plant, 

 natural size, also an enlargement (Fig. 1082), to show the little white 

 spots from which it gets its name.
