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-globule.-. Asci 8-spored. cylindrical, short-stipitate, 

 50xl2//; paraphyses filiform. Sporidia uniseriate, ovate-elliptical 

 2-celled, 9x4 p., upper cell f-f 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. 



HERPOTRICHIA, Fekl. 



i 



Symbolae Mycol. 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 Herpotrichi^ have the sporidia 

 oblong and obtuse.

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

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

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

 150x16 ft, 8-spored, paraphysate. Sporidia ovate-oblong, sometime? 

 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.
