numerous, yellowish-white, acuminate spines often 1-3 times branched, 

 200-300 x 18-22 //, very thick walled and enclosing a central canal 

 filled with oil-globules. Asci 8-spored, cylindrical, short-stipitate. 

 50x12//; paraphyses filiform. Sporidia uniseriate, ovate-elliptical? 

 2-celled, 9x4//, upper cell - the length of the sporidium, olive- 

 brown, with a large nucleus, lower cell conical, hyaline. 



On decaying bark of Eucalyptus, San Francisco, Cal. (Harkness). 



This species is anomalous in' this genus on account of the " olive- 

 brown" upper cell of the sporidia, but if these are really two-celled, 

 it cannot belong in Rosellinia, which includes only species with one- 

 celled sporidia. The branching spines are also unusual. We have 

 seen no specimens, and take the diagnosis from the publication cited. 



HERP0TRICHIA, Fckl. 



Symbolse My col. p. 146. 



Perithecia superficial, spherical or subspherical, mostly of firm 

 texture, coriaceous to subcarbonaceous, hairy or bald. Sporidia fusi- 

 form or oblong, 2- or more-celled, hyaline or brown. 



Winter in Die Pilze makes fusiform sporidia {i. e. thicker in the 

 middle and narrowed towards each end) the distinctive character be- 

 tween Herpotrichia and Lasiosphceria. Some of the species with 

 uniseptate sporidia here included in Herpotrichia, have the sporidia 

 oblong and obtuse.

 H. Rhenana, Fckl. Symb. p. 146, tab. Ill, fig. 7. (Plate 19) 



Perithecia scattered or gregarious, nearly free, rather large, glo- 

 bose, fugulose, densely clothed with long, brown, decumbent, creeping 

 hairs, flattened above, with minute, truncate ostiola. Asci oblong, 

 150x16 //, 8-spored, paraphysate. Sporidia ovate-oblong, sometimes 

 curved, rounded at the ends, constricted in the middle, hyaline, at first 

 2-celled, later 4-celled, brownish, 21-28 x 8 /*. 



On decaying culms of grasses. Not yet reported as found here, 

 but given as a typical species to illustrate the genus.
