ON CHCETOPHOMA. 
Chaetophoma anthelmintic a. Che. 
Epiphylla, atro-fuliginea. Hyphis byssoideis repentibus, brun- 
neis, ramulosis, ramulis conidiiferis erectis, cladosporoideis. Peri- 
tlieciis globosis-depressis, brunneis (*01 mm.) Sporis arcte ellip- 
ticis, obtusis, hyalinis (’007 x *003 mm.) 
On fading leaves of Chenopodium anthelminticum. S. Carolina. 
Rav. (2088.) 
In this instance the perithecia are seated amongst the threads of 
a Cladosporivm. — Plate 119, fig. 5. 
Chaetophoma Catalpae. Che. 
Hypophylla, effusa, brunnea. Hyphis byssoideis repentibus, 
flexuosis, ramulosis, paucis. Peritheciis globosis, brunneis (*04- 
*05 mm.). Sporis subovatis, hyalinis (’002 x '0015 mm.) 
On dead leaves of Catalpa cordifolia. S. Carolina. Rav. 
(2302.)— Plate 118, fig. 4. 
In this species the hyphae are not so profuse or distinct as in 
most of the others. In some conditions the threads are nearly 
obsolete, in others they constitute a Cladosporium , with small uni- 
septate spores. 
B. Perithecia elongated. 
Chsetophoma cycadis. Che. 
Hypophylla, maculseforma, sparsa, brunnea. Hyphis byssoideis 
ramosis, repentibus, ramulis conidiferis assurgentibus, macro sporo- 
ideis. Peritheciis lagenseformibus, superne attenuatis, fuscis (’015 
X '09 mm.) Sporis ellipticis, hyalinis ( 005 x *003 mm.) 
On leaves of Cycas. S. Carolina (2543.) 
Seated amongst Macrosporium commune , in velvety patches on 
the under side of the leaves. In this species we saw the expulsion 
of the spores in a long continuous tendril during examination under 
the microscope. — Plate 119, fig. 6. 
Other species have been met with, as for instance one on dead 
sheaths of maize ( Zea mays ) ; and another mixed with Clado- 
sporium and Macrosporium on leaves of oleander, but these have not 
been described, as they require further investigation and study. 
The species already enumerated will be sufficient to illustrate 
the scope of the genus, of which specimens of four will be issued 
in Ravenel’s “ American Fungi.” Up to the present we have not 
met with any genuine European species. 
The plates in illustration will be issued in a subsequent number 
of this journal.
