EHOPALOPSIS. 
In this genus, as proposed (Vol. xi., p. 93), some additional 
details are required. 
a. Stroma simple. 
1. Rhopalopsis coenopus, {Mont.) No. 1488. 
Sporidia lanceolate, •04--045 x *009 mm. 
2. Rhopalopsis aggregatum, (TF. ^ C.) 1427. 
3. Rhopalopsis Angolense, (TF. C.) 1519. 
Sporidia •012-’015 mm. long. 
4. Rhopalopsis clavus, (Fr.) 
Sporidia lanceolate, *04 X -01 mm. 
5. Rhopalopsis confusum. Berk. CooTce. 
Gregarium, stipitatum, simplex. Capitulis globoso-depressis, 
glaucis, demum nigris, in stipitem flexuosam attenuatis ; perithe- 
ciis innatis, globosis, ostiolis punctiformibus. Ascis sporidiisque (?). 
On wood. Brazil. 
6. Rhopalopsis micropus, {Berk.) 1491.

stipitatis, superne applanatis, dense congestis, atris, opacis, simpli- 
cibus, rarissime confluentibus, stipite brevi, ruguloso, infra attenu- 
atis. Peritbeciis minutis, numerosissimis, compressis, prominulis. 
Ascis cylindraceis. Sporidiis ellipticis, incequilateralibus, continuis, 
fuscis, 'OOS-’Ol X ‘004 mm. 
On bark. Brazil (Glaziou, 8542, 8543). Ceylon (No. 60). 
Although resembling B. coenopus in habit, easily distinguished 
by the very much smaller perithecia, and different sporidia. 
b. Stroma multipartite.
