754. Puccinia truncata, n. s. Maculis obsoletis ; soris oblongis 

 epidermide scariosacinctis; sporisobovato-oblongisapice truncatis. 

 On leaves of Iris foetidissima, Isle of Wight, Rev. A. Bloxam. 



Sori oblong, 1 line or more long, brown, surrounded by the 

 scarious epidermis; spores obovate-oblong, even, attenuated below, 

 upper cell abruptly truncate. 



755. Epitea Baryi, n. s. ; Epitea, Bary, Brandpilz, tab. 4. 

 fig. 4. On leaves of Brachypodium pennatum, Rev. A. Bloxam, 

 Gopsal. 



Dr. De Bary's plant is on the leaves of Lolium perenne ; the 

 cystidia have in general an abrupt globose head, which seems cha- 

 racteristic of the species, which has not been observed previously 

 in Great Britain. 



756. Institale effusa, Fr. Summ. p. 447 ; Ptychogaster albus, 

 Corda, Ease. 2. p. 23. tab. 12. fig. 90. About the roots of 

 Scotch fir, Apethorpe, Norths., autumn. 



Excellently figured by Corda, whose plant is exactly ours, and 

 which Fries states to be his Institale effusa, a species of which 

 the name only has at present been published. It approaches also 

 very closely to Institale maccimttj Schwein, which differs only in 

 its redder spores, which are however of the same size and form. 



757. Atractium flammeum, Berk, and Rav. Breve subcylin- 

 dricum cinnabarinum deorsum album pruinosum ; sporis longis 

 fasiformibus. 



On the bark of living willows, Penzance, J. Ralfs, Esq. It 

 has been found in similar situations peeping up from beneath 

 lichens, by H. W. Ravenel, Esq., in South Carolina. 



Scarcely ^ a line high, cylindrical, flame-red, pminose below; 

 head convex. Spores "003 inch long, curved, fusiform, hyaline, 

 with six or more septa seated on long sporophores. 



This has just the habit of Stilbum aurantiacum, but is at once 

 distinguished by its peculiar spores. Mr. Ravenel in a late 

 communication suspects it to be a state of some Nectria. 



758. Helminthosporium sticticum, n. s. Maculis gregariis 

 punctiformibus nigris ; sporis oblongo-clavatis uniseptatis. On 

 decaying leaves of grasses, Batheaston. 



Disposed in minute specks, jet-black, threads fasciculate, 

 nodose or irregular; spores -0016 of an inch long, oblong, 

 swollen above, uniseptate. 



The punctiform spots, black, not olivaceous hue, and uniseptate 

 spores are the characteristics of this species, which is nearly allied 

 to H. arundinaceum. The threads of the latter are coarser, and 

 the habit diff'use.
