short, oblong-elliptic, hyaline, sometimes slightly constricted in 

 the centre, uniseptate. The septum appears to be continued 

 through the external as well as the internal membrane. 



The sporidia have much the form which is so common in the 

 genus Diplodia. "We can find no trace of the species in authors.

639. S. (Subtectse) intermixta, n. s. Minutissima sparsa epi- 

 dermide tantum tecta nigra ; peritheciis depressis supra convexis 

 perforatis; ascis clavatis; sporidiis biseriatis hyalinis clavato- 

 fusiformibus triseptatis. On rose-twigs mixed with Spharia fus- 

 cella, but much smaller. 



Scattered, seated beneath the cuticle. Perithecia very minute, 

 convex, depressed, perforated in the centre, black. Asci clavate ; 

 sporidia biseriate, hyaline, clavato-fusiform, triseptate. One of 

 many undescribed species comprised by authors under the name 

 of 8. Epidermidis. The asci are large for the size of the peri- 

 thecia.

*j8>. Epidermidis, Fr. Scler. Suec. no. 19. In two copies of 

 the ' Scleromycetes Suecica?/ which we have the opportunity of 

 examining, three things at least appear under this name, all 

 marked no. 19 : — 1. A Sphceria on elder, which appears from its 

 long sporidia to be a state of &. sepincola, or possibly of S. 

 Lebiseyi; 2. another on elder, which we consider the type of the 

 species with uniseptate sporidia, consisting of two apposed, rather 

 irregular cones; and 3. a production on some Lonicera, which 

 appears to be the same with a minute Phoma, common in this 

 country on the same matrix. It appears in this case, as in Sph&ria 

 sepincola, the best course to consider species agreeing in struc- 

 ture, though differing somewhat iu size, as mere forms of one 

 type. "We refer therefore to this species, one which we find on 

 privet with very superficial, but rather thick and brittle peri- 

 thecia, and sporidia twice as large and more constricted at the 

 septum and in the centre of the two cones which compose them. 

 It occurs on the same twigs with Tympanis saliyna, which when 

 young resembles closely a sub-cuticular Sphieria with a broad 

 truncate ostiolum.

Common on box leaves, on which several productions grow ; 

 comprised in Fries' 'Systema' under the name of S. atrovirens. In 

 the present species the sporidia are short, oblongo- elliptic, hyaline, 

 biseriate, slightly attenuated at either extremity.
