On stems of Kochia pro strata there is f. Kochiae (Rouni. Fung. 

 SeL Gall. no. 514!) mixed with other fungi, notably Camaro- 

 sporium Roumegueri, var. Kochiae, Sacc. But Rouni. Fung. 

 Gall. exs. no. 859!, and Fung. Sel. Gall. exs. no. 214! are both 

 quite different, though under the same name. 



Diedieke seems to regard a Phomopsis on A triples as belonging 

 to Diaporthe picea, Saec. 



835. Phoma macropvrenia,, Thuia. 



On the Kew exemplar of Thunien's exsiceatuni, named in his 

 writing " Phoma macropi/reniiim, Tirana, nov. spec./' are three 

 fungi, all black and all somewhat similar, intermingled, but 

 differing from one another in the character of the spores and 

 sporophores. 



The first is that intended by Thumen, a true Pit o ma, having 

 an all-round pycnidium with a wall about one cell thick. 



I. — Phoma macrofykexia, Thiim. 



Pycnidia gregarious, immersed, covered by the epidermis, then 

 erumpent, subsuperficial, globe »>e, about 100 ju diam., black, 

 pierced at the vertex by a minute impressed pore; texture truly 

 Phoma-like, brown, parenchymatous Spores ellipsoid, oblong, 

 or subcylindrical, rounded and scarcely subacute at both ends, at 

 times somewhat curvulous, 6-8 x 2' 5-3 p (or rarely 10 p long), 

 rather variable, and having, apparently, in many cases, as 



Thumen savs, " two large nuclei/' i.e. guttules, one at each end. 



t 



No perceptible sporophores : one spore was seen which appeared 



to have a median septum. (Fig. 8, a.) 



On dead stems of Ricinus communis, Coinibra, Portugal, legit 



Mailer (one of the original specimens" issued by de Thumen in 



Flora Jusitanica). 



The specimens issued by Ivojimeguere under the same name (in 

 Fung. Gall. sel. no. 4349 !), from Luehon. are quite different. 



The second fungus is a Phomopsis, which is different from 

 Phomopsis Ricini described below: it mav belong 1 to Diaporthe 





v»' 



wMch should, it seems, be considered distinct from T). spiculeM, 



7^ its. 



II. — Phomopsis l*r \ktervisa. sp. nov. 



Pycnidia copio>a, subgreoaiia, nee conferta, atra, rotundatt, 

 apice pertu>a, intei-diun eontluentia, eu. 250 p diam., velata, dein 

 erumpentia, denique parte superiore crassa dilapsa discum 

 incusum atrum opaeum epideimide fraeta cincturn relinquentia. 

 Sporulae copiosae, cylhulrae^o-ellipsoideae vel ihasoideae, utrinque 

 subacutae, 1-2-parriguttulatae, 8-10 x 2 2*5 p, spwophbris 

 stipatis, subulatis, erectk. achrois, apice saepe aeutis, 16-20 x 



1*5-2 a, e strato dilute olivaeeo oriundis sufhiltae. (Fig. 3, b.)
