FETCH : 
The American species, specimen on Rhus examined, is 
practically identical. Its perithecia are clustered, about 
0*5 mm. diameter, with a minute conical ostiolum ; the apex 
is not flattened. The surface is echinulate, with conical 
spines, up to 30 ^ high, which are not so markedly thorny 
along their sides as in the Ceylon specimens. The asci are 
smaller than in the Ceylon species, the sporiferous part 
measuring 55-65 X 16-18 pi, and the pedicel about 30 pi ; but 
the spores are larger, 8-10 X 1*5 pi, hyaline. The spores do 
not appear to be quite mature, but even so they are longer 
than in Fr. Broomeiana. 
It will be noted that Berlese’s measurement of the spore 
agrees with that of Fr. Broomeiana, and his measurement of 
the ascus with Fr. brevibarhata. If both his measurements 
are from the same American specimen, it must be assumed 
that the spores may vary 5-10 X 1*5-2 pi. The earliest 
name is Sjphærîa Broomeiana. 
188. — Trichosphæria acanthostroma (Mont.) Sacc. 
Thwaites’s 1029 was referred to this species by Berkeley 
and Broome. It consists of a thin, purple-brown, somewhat 
velvety stratum of mycelium, extending for several centi- 
metres, and composed of suberect, rigid, flexuose hyphæ, 
with simple or forked, acute, lateral branches. The peri- 
thecia are scattered, 0*2 mm. diameter, globose, without an 
evident ostiolum, collapsing into a cup when dry. The 
perithecial wall is brown by transmitted light, cellular, 
almost membranous, and smooth. The asci are eight-spored, 
with narrow-oval, hyaline, continuous spores, 5-7 X 2 pi, but 
they do not appear to be quite mature. 
189. — Trichosphæria regulina (B. & Br.) Sacc. 
Thwaites’s 1075 was described by Berkeley and Broome as 
“ Sphæria (Byssisedæ) regulina. Peritheciis minutissimis 
ovatis obtusis e mycelio tenui oriundis ; ascis clavatis ; 
sporidiis biseriatis oblongis curvatis tenuibus. Perithecia 
invisible to the naked eye ; asci *003 (inches) long ; sporidia 
*0008 by *0002.” In Saccardo, Sylloge, I., 454, it is listed 
under Trichosphæria.
