do not know, but it was first called Xylaria ectogramma by Berkeley 

 and afterward referred to grammica. Xylaria exalbata, from Ceylon, 

 referred to grammica as a synonym, from our photograph, seems quite 

 different. We present (Fig. 925) a photograph of this characteristic 

 species from specimen received from Dr. J. Dutra, Brazil. Also an 

 enlargement (Fig. 926) to show the nature of the striations. 



SPECIMENS. We have fine collections from Brazil: Rev. Rick (310), Rev. Torrend (394) 

 and Dr. J. Dutra. AlsD from Angola, Africa. J. Gossweiler, young specimen of Xylaria variabilis. 



RELATED SPECIES. 



XYLARIA VARIABILIS (cfr. Myc. Notes, page 636). This is quite close to 

 grammica, perhaps same species. The clubs are more slender, the lines not so 

 prominent, the "bark" separable from the stroma, and on comparison they seem 

 different, though on basis of our immature collection, no just estimate can be made. 

 We have specimens from J. Gossweiler, Angola, Africa. 



XYLARIA ZELANDICA, from New Zealand (not Xylaria Zeylanica from 

 Ceylon), is a small species with a slender stipe; said to have large, fusiform spores 

 10 x 32-35. The figure shows similar lines on the club, but we can not make them 

 out on our photograph of the type. 



XYLARIA STRIATA, from China is figured as being about same stature as 

 Xylaria grammica and having similar lines. The clubs are more acute, stems thicker, 

 and spores 5-8 x 15-20. Our photograph of the type, however, does not agree with 

 the published figure by any means. 



Fig. 927. Fig. 928. 



XYLARIA GUYANENSIS (Fig. 927) Clubs 3-4 cm. x 6-7 

 mm., with short stipe l-l^ cm. x 4 mm., solid, with white stroma, 

 disposed to become hollow in the center when old. When young, 

 covered with a thin, black crust; when old, smooth, even. Peri- 

 thecia regular, rather distant, immersed in the stroma. Ostioles sur- 

 rounded by a white disk. Spores 4-5 x 8-12. 



The peculiarity of this species, the white ring around the ostiole, 

 was noted by Montagne. The perithecia are also more distant and 

 regular than in most species, and at first the mouths are papillate, 

 viz., covered with a thin crust. The white ring does not show until 

 the crust peels off. We are indebted to Dr. Brenckle for examination
