860 SPH^RIACEI. 



Brown or nearly black, subiculum effused, consisting of interwoven, Creep- 

 ing hairs. Perithecia crowded, ovate, clothed with long hairs, attenuated, 

 and more or less denuded above, and when dry collapsing with their papil- 

 Iffiform ostiolum. Sporidia biseriate, fusiform, consisting of two opposed 

 cones constricted at the juncture, and sometimes above the first nucleus, 

 each division containing one or more globules.- — B. <k Br. 



2573. Sphaeria pilosa. Pers. " Velvety Spbasria." 



Black; perithecia minute, roundish- ovate, nearly even, beset 

 with short hairs ; ostiola simple ; sporidia colourless, elliptical, 

 uniseptate, or with the endochrome bipartite. — Pers. Ic. ^ Desc. t.

On decayed wood. Common. [Low. Carolina.] 



A small species, like *S^. pulvis-pyrius, but decidedly hairy. Sporidia 

 f'0003-*0004 in.) 'OOrG-'Ol m.m. " We have observed oblong couidia, rather 

 irregular in outline, terminating the hairs. The asci in the same specimens, 

 besides the eight linear, oblong, somewhat sigmoid sporidia had at the tip 

 a globose, smooth, or slightly granulated body ('0003 in.) 0076 m.m. in 

 diameter, the nature of which we were unable to determine.' — B.<kBr. 



2574. Sphaeria sexdecexnspora. Cooke. " Sixteen-spored 



Sphgeria." 



Scattered ; perithecia small, ovate, beset with rigid, erect 

 hairs (at first covered, then bursting through the cuticle), black; 

 ostiola prominent ; asci elliptical ; sporidia sixteen, crowded, 

 broadly lanceolate, 3-5 septate, with transverse divisions, hyaline. 



On twigs. Shere. (Dr. Capron.) 



This pretty little Sjjhceria is very distinct from its allies. It is included 

 doubtfully with the Villosoi j there is no subiculum, and only occasionally 

 the perithecia are wholly exposed. Sometimes there are more than five 

 septa in the sporidia, which are very variable in size. 



c. Denudatce. 



Subiculum none ; perithecia smooth, rounded at the base, 

 nearly free ; ostiolum persistent ; adnate,su2jerficial. — Fr. S.M.
