292 DR. F. WELWITSCH AND MR. F. CURREY'S FUNGI ANGOLENSES. 



HYMENULACEI, Er. 



1 1 vmexula vulgaris, Er. Eorrna rosea. 



Hah. Ad folliculos Apocynacearum prope Luxillo, Pungo Andongo, Jan. 1857. No. 20. 



SCLEROTIACEI, Er. 



Sclerotium stipitatum, Berk. & Curr., Trans. Linn. Soc. vol. xxiii. pp. 91, 93. 



Hub. Ad radices arborum emortuarum, sub terra ad profunditatcm 1-3 ped. absconditum, in arvis Solano 

 tuberoso cultis, prope Lopollo, Huilla, Apr. et Maio 1861. No. 138. 



Obs. In India this species has hitherto heen fonnd only in the nests of the white ant. 



S. flavidoi, Welw. & Curr. Tubercula varia, subglobosa, reniformia vel deformia, 



flavida vel fulva, a mole grani sinapis (vel minus) ad pisi parvuli crassitudinem 

 varia . 



Hub. In declivis parce graminosis, ad 800-1000 ped. altitudinis, locis humidiusculis ad oras silvarum 



primitivarum ad terram inter caespites putrescentes, Insula Principis in sinu Benin, Sept. 1853. No. 27. 



Under No. 37 we find Panunim plicatimi bearing an Ergot of the kind common in 

 other grasses. As there is no fruit on the Ergot, we can only place it here amongst the 

 Sclerotiacei. It would doubtless, at the proper season, produce some species of Claviceps. 



SPORIDESMIACEI, Er. 

 Sporjdesmium celatum, Welw. & Curr. Eoliicolum, mycelio sub folii cuticula nigre- 



facta dense compacto ; sporae fusca?, leviter curvatae vel fere rectse, 3-5-septatse, in- 

 terdum substipitatae, pedicello pallidiore. 



Hub. Ad folia plantae e familia Euphorbiacearum, Coango, Golungo alto, Octob. 1855. No. 77. 

 Tab. 17. fig. 15, spores, highly magnified. 



Obs. The place and mode of growth are somewhat unusual for a Sporidesmium, hut 

 the characters are not sufficiently definite for the formation of a new genus. 



DEMATIACEI, Fr. 



5 



Helminthosporitjm Cordis, Welw. & Curr. Epiphyllum, sistens maculas circulars 



1-4 lin. diam., fuscescentes, hie illic confluentes, e fills rigidulis crispulis exarticulatis 

 parce ramosis fusco-luteis conflatas ; ramulis patentissimis, plerumque leviter cur- 

 vatis, crassitudine filamenta primaria sequantibus, ad basin hie illic fructiferis; 

 sporis rectis vel curvulis, ellipsoideo-cylindricis, obtuse apiculatis, filamentis duplo 

 crassioribus, 3-5-septatis, pellucidis. 



rem foliorum Cordite spec, in silvis primitivis prope Sange, Golungo a , 



Hab 



Martio 1856. No. 1. 



Tab. 17. figs. 9, 10 & 11, filaments and spores, x highly. 



ECIDIUM. 



TJREDINEI. 



A few YEcidm were collected, to which we do not venture to give specific names. 

 Fries remarked long since (Syst. Myc. iii. 512) :— « JEcidium in singula planta describe*
