XYLARIA GRACILIS, FROM MARCIAL R. ESPIXOSA. 

 CHILE (Fig. 1008). Stem slender, smooth, rarely simple, usually 

 branched, bearing three or four clubs. 

 Clubs i-i l /2 cm. long, acute, 2-3 mm. thick, 

 fragile. Stroma white, well developed. 

 Perithecia partially imbedded, forming a 

 tubercular club. Spores 6-7 x 20. 



We saw but one other Xylaria in the 

 museums that branches near the base, 

 bearing several clubs, viz., Xylaria Gard- 

 neri, which has no relation to this. Cooke 

 figures two other such species, viz., Xylaria 

 caespitulosa and Xylaria rhizomorpha, but 

 both were purely fanciful, the types having 

 simple unbranched stems. Theissen (t. 10, 

 fig. 4) figures what appears to be this plant 

 under the name Xylaria fasciculata, but there is nothing in the 

 original of this description to indicate that it is branched. Xylaria 

 gracilis was named in manuscript by Klotzsch (cfr. Sacc., Vol. I, p. 

 317), and the type, all heretofore seen by me, is at Kew. It is an 

 old collection by Humboldt from South America. 



XYLARIA CONCURSA, FROM MARCIAL R. ESPINOSA, 

 CHILE (Fig. 1009). Stem branching and bearing one or two fertile 

 clubs and one or two conidial clubs. 

 Clubs 13/2-2 cm. by 3 mm. cylindrical, 

 even, acute, or rounded at the apex. 

 Perithecia imbedded, not protruding. 

 Stroma white, scanty. Spores 6-7 x 14. 



I know but one other species that 

 branches at the base in this manner, 

 viz., Xylaria gracilis (cfr. above), which 

 has rugulose, not even, clubs. There is 

 no other species I believe that bears 

 conidial and ascigerous clubs or separate 

 clubs, but concurrent. Still it is possible 

 that Xylaria gracilis and Xylaria con- 

 cursa are different stages of the same 

 species. Fig. 1009. 



XYLARIA TUBERIFORMIS. FROM J. B. CLELAND, 



Spores 8 x 1 6 described 



AUSTRALIA, as named from New Zealand, 

 as 25 mic. We present 

 Fig. 10 10 the type, also 

 Fig. 1011, specimens from 

 Dr. Cleland which show 

 that it is not always "tu- 

 beriform." Xylaria clavu- 

 lus as illustrated by Cooke 

 seems the same plant, but Fig . 10 i . 



the type has no resemblance to it. Xylaria globosa, named by Fries 

 as Hypoxylon, and described by Rehm as Xylaria, is the same to the 



678 



Fig. 1011.
