take this opportunity of stating that Mr. Thwaites has found 

 both Stigonema atrovirens and mamillosum in fruity and in both 

 instances perfect asci and sporidia exist. The genus then does 

 not belong to Alga, but to Collemals. It appears that Sp. affinis 

 is nothing more than the fruit of the Stigonema. 



608. S. muscivora, \\. s. Mycelio eftuso niveo lanoso peri- 

 theciis congestis aurantiis semi-immersis ovatis ; ostiolo papillse- 

 formi ascis clavatis ; sporidiis breviter fusiformibus. On mosses 

 upon the miid tops of walls in winter. King's CliiFe. 



Mycelium forming white lanose patches 3 inches or more in 

 diameter, and rapidly destroying the moss on which it grows. 

 Perithecia collected iu little groups more or less connate, half 

 immersed in the mycelium, bright orange, ovate, sometimes col- 

 lapsing laterally, orifice papillceform. Asci clavate; sporidia 

 elliptic, pointed at either end, with a central septum, and the 

 endochrome in either ai'ticulation bipartite, so that there are 

 probably three septa when the sporidia are quite mature. 



Readily distinguished by its peculiar habit. The spores differ 

 from those of S. Peziza, which collapses more and more regularly. 

 We have this species from South Carolina on Jungermannice. 



*609. S. cucurbitula, Tode. 



This is easily distinguished from all similarly coloured species 

 by its asci being filled with numerous minute curved sporidia. 

 In our copy of ' Scler. Suec' no. 183, it is substituted for Sph. 

 coccinea. 



610. S. flavida, Corda, Fasc. iv. t. 8. f. 117. Nedria flavida, 

 Fr. Summa, p. 388. On the decayed trunk of a tree, Leigh Wood, 

 Bristol. 



The sporidia of this are totally different from those of Hypocrea 

 farinosa, which it resembles much in outward appearance. In 

 the latter they are minute and elliptic, in the present species 

 elongated, fusiform and curved. 



611. S. funicola, n. s. Peritheciis sparsis aurantiis ovatis sur- 

 sum attenuatis pilis sparsis brevibus obtusis vestitis ; ascis clavatis, 

 sporidiis oblongo-ellipticis triseptatis. On decayed rope, King's 

 Cliffe, Oct. 1841. 



Minute, scattered ; perithecia ovate, attenuated above, clothed 

 with short obtuse colourless hairs ; orifice obtuse, without any 

 distinct papilla. Asci clavate ; sporidia oblong-elliptic when seen 

 from the back, subcymbiform when seen laterally. The endo- 

 chrome is more or less perfectly divided by septa into four parts. 



612. S. papaverea, n.s. Conferta ; peritheciis globosis excepto 

 ostiolo maximo piano orbiculari radiato-sulcato albo velatis 

 areolatis; ore rotundo. On rotten stumps, Batheaston, March 

 1850. 



Widely effused, crowded, springing from a brown mycelium ;
