194 .— Chætosphæria xanthotricha (B. & Br.) Sacc. 
This was described by Berkeley and Broome as “ Sphæria 
( Villosæ) xanthotricha. Peritheciis aggregatis flavo-lanatis ; 
ostiolo punctiformi nigro ; sporidiis subcymbiformibus 4-5- 
septatis. Sporidia *00065 (inches) long.” It was included 
in Saccardo, Sylloge Fungorum, I., p. 95, as Chætosphæria. 
The perithecia are about 0*4 mm. diameter, superficial, 
gregarious, globose, with a papillate ostiolum, black, clothed, 
except at the ostiolum, with yellow spreading hj^phæ, which 
extend slightly over the substratum at the base. The peri- 
thecial wall is parenchymatous, not carbonaceous, dark brown 
when mounted. The external hyphæ are septate, 3-4 [l 
diameter, slightly inflated at the tip, and strongly encrusted ; 
yellow, oval, continuous conidia, 5-7 X 3-4 are present, 
apparently borne on the external hyphæ. The asci are eight- 
spored, about 60 X 8 pi. The spores are fusoid, three- to five- 
septate, slightly constricted at the septa, ends obtuse, pale 
fuscous, 16-20 X 5 [L. It would perhaps agree better with 
Lasiosphæria than with Chætosphæria. 
195.— Melanomma Vesuvius (B. & Br.) Berk 
Berkeley and Broome described this species as Sphæria 
(Pertusæ) Vesuvius B. & Br. Sparsa ; peritheciis magnis, e 
basi truncata conicis, ostiolo acuto ; sporidiis fusiformibus 
fuscis biconicis, medio contractis, utrinque uniseptatis. On 
decayed wood. Perithecia | line across and as much high ; 
sporidia *0018 by *0005 (inches).” It was included in 
Saccardo, II., 119, as Trematosphæria. Berlese, in leones 
Fungorum, I., p. 36, tab. 24, fig. 2, referred it to 
Melanomma, 
The perithecia occur on decaying palm fronds. They are 
scattered, almost superficial, with the base slightly immersed, 
black, smooth, carbonaceous, conoid, with a minute conical 
ostiolum, base flat, 0*75-1 *5 mm. diameter, 0*5-1 mm. high. 
The spores are pale to dark brown, fusoid, three -septate, 
constricted at the median septum, straight or slightly curved, 
ends obtuse, 38-48 X 6-8 (ji, with one of the middle cells 
often inflated to 10 ^ wide.
