SOME EXOTIC FUNGI. 
By M. C. Cooke. 
Sphaeronema tenuir ostris, CTce. 
Gregarious, perithecia black, depressedly globose, seated 
beneath the cuticle, which is pierced by the long slender beaks, 
which are gradually attenuated towards the pallid apex, and three 
to four times as long as the diameter of the perithecia. Sporules 
cylindrical, rounded at the ends, straight or slightly curved, con- 
tinuous, hyaline (21 x 5 fP) seated on long sporophores. 
On bark. Westbrook, Maine, U.S.A. {Rev. E. C. Bolles). 
Polyporus (Lobati) talpae, CTce. 
Imbricato-multiplex, e carnoso lentus, subcoriaceus, pileis 
dimidiatis, latissimis, flaccidis, breviter velutinis, demum profunde 
rugulosis, fuligineis; ambitu pallidioribus ; stipitibus (?); poris 
mediis, angulatis, subsequalibus, vix dentatis, concoloribus. 
Contextu pallido. 
On stumps. Minas Geraes {Glaziou 16,679). 
Pileus 10-12 in. diam., \ in. thick. Tubes scarcely exceeding 
1 mm. long. Near P. giganteus and P. acanthoides. 
Lentinus Camaroensis, CTce. Sf Mass. 
Pileo carnoso-coriaceo (6-10 in. diam.), infundibuliformi, 
ochraceo-pallido, velutino, disco squamoso-diffracto, margine 
patente, tenui, acuto ; stipite centrali, vel subexcentrico, aequali, 
solido, tomentoso (3 in. long, 1 in. diam.) adscendente. Lamellis 
subconfertis, linearibus, angustis, decurrentibus, obscurioribus. 
On trunks. Rio del Rey, Camaroons {H. H. Johnston 105). 
Allied to L. Barteri, Berk., but quite distinct in the velvety 
pileus and stem. 
Tuberculina Africana, CTce. Sf Mass. 
Sporodochiis hemisphaericis vel globoso-depressis, exiguis, 
purpureo-fuscis ; conidiis globosis, hyalinis, 3-4 /x, basidiis 
crassiusculis, continuis, 3 p. 
Around an PEcidium , on Ophiocaulon cissampyloides. Gaboon 
(E. L. Simmonds). 
The spores of the JEcidium are hexagonal, 17-20 /£, which 
seems to indicate a distinct species, but the PEcidium is not in 
sufficiently good condition for description. 
Phoma Oryzae, CJce. Sf Mass. 
Perithecia minute, scattered, at length piercing the cuticle, sub- 
globose, black. Sporules oval, continuous, hyaline, on short 
basidia, 3 x 2 p. 
On rice straw. Calcutta, India. 
Gonatobotryum (Dichobotryum) dichotomum, CJce. Sf Mass. 
Effusum, fuscum. Hyphis fertilibus erectis, septatis, bis terve 
dichotomis, conidiis ad angulos gerentibus, ellipticis, continuis 
hyalinis, vel pallide olivaceis, 15 X 10 p, glomerulis subglobosis.
