asci, curved when free, 35-50 x 3-3| ^, slightly tapering from the mid- 

 dle to each end. 



On old Diatrype stigma and on the bark of decaying oak limbs, 

 New Jersey and Carolina. 



We can not say positively that Sphoeria cerea, B. & C. and 

 OpMonectria Everhartii, E. & G. are the same, but the probability 

 of their identity is so strong that we have assumed it to be a fact. 

 There may also be some question of geneiic relationship : but if Nec- 

 trlu melina, Mont, can be refei'red to OpMonectria, as is done in i-!acc. 

 Syll. II, p. 563, our species may properly go there too, having sporidia 

 still narrower than in that species. 



0. coccicola, (E. & E.) 



Neciria coccicola, E. & E- Journ Mycol. II, p. 39, 

 Dialonectria coccicola, E. & E. I. ^-. II, p. 137. 



Perithecia cespitose, membranaceous, about \ mm. diam. and J 

 mm. high, flesh-color, becoming dirty bulF when mature, obovate, asto- 

 mous, surface roughish, with a few scattered, white, rudimentary hairs, 

 or at length bald. Asci clavate-cylindrical, 150-190 x 20 /^, witli abun- 

 dant, rather stout paraphyses. Sporidia eight in an ascus, clavate-cyl- 

 indrical, multinucleate, hyaline, 110-140x6-7 // at the upper end, 

 attenuated below. 



On dead scale insects on bark of living orange trees, Florida 

 (Scribner). 



The groups of perithecia are seated either on the shells of dead 

 insects or on the bark itself, with a subiculum more or less distinct, 

 composed of white, decumbent or prostrate hairs of the same charac- 

 ter as those found on the perithecia themselves. The species seem to 

 be quite distinct. 



GIBBERELLA, Sacc. 



Mich. I, p. 43. 



Perithecia either cespitose and stromatically connected or separate. 

 Asci 8-spored. Sporidia subfusoid, 3-pluri-septate, subhyalino. The 

 substance of the perithecia is of a blue or violet tint. 



G. acervklis, (Moug.) 



Sphczria acervalis, Moug-. in Fr. Elench. II, p. S3. 

 Gibberella acervalis, Sacc. Syll. 4979- 



Emergent, bare and black, collected in small heaps or clusters. 

 Perithecia subconnate, globose, rugulose, at length umbilicate. Asci 

 oblong, 70 X 10 //. Sporidia ovate-oblong, 3-septate, hyaline, 18 x 6 /i.
