258 FUNGI. [Sph(Bria, 



ovate Immersed raising the wood into minute papillae, ostiola 

 obtuse erumpent. Pers, Ic. et Descr, t. 1./. 8. Fr. Sj^sL Myc, 

 V. 2. p. 480. 



On dry wood. Apethorpe, Norths. Rev. 31. J. Berheley on the 

 trunk of a felled tree. — My plant appears to be the same as what is 

 figured by Persoon, aud is quite different from S. milliaria. The outer 

 surface of the wood, covering the perithecia, is discoloured and of a 

 brownish black, but thestain penetrates only very slightly and is by no 

 means crust-like. The contents of the perithecia, in the dry state at 

 least, are white. 



147. S. ocelldta, Fr. (eyiet Sphcerici) ; scattered, perithecia 

 immersed globose persistent black, ostiola solitary umbilicate 

 exserted from a truncate white disc. Fr, Syst. Myc. v. 2. p, 

 480. >S'. brevis. Sow, / t. 394./. 4. 



On branches of ash, willow, &c. Sowei-hy, apparently on ash.--I 

 have no doubt that the plant of Sowerby is the same as that of Fries. 

 Externally it at first sight exactly resembles the state of Stictis radiata 

 with an entire border, but on more minute examination it might be 

 taken for S. leucostoma or S. nivca, but the perithecia are solitary 

 without any conceptacuhim. 



148. aS'. salicella^ Fr. {ininute willow Splicsria) ; covered, 

 perithecia distinct minute seated beneath elongated pale patches 

 of the epidermis, ostiola cylindrical erumpent. Fr, Syst. Myc, 

 V. 2. p. 377. Scler. Suec. / n. 188. 



On willow branches ; common. — This is placed in the Sysfema 

 Mycologicnm in the division Concrescrntes, but in the new issue of 

 Scleromycetes Suecics in the present division with which it seems to me 

 to accord best. This species is marked in Sowerby's Herbarium as ^S*. 

 subcorticalis. Sow. t. 296, but the perithecia in the figure are much 

 larger, and therefore very possibly he may have had S. ditopa in view. 

 I have in vain looked for that species on Rhamnus catharticus. 



149. S. corticis, Sow. (tliousand-dot SphcBvia) ; scattered 

 perithecia globose persistent black ostiola slightly prominent, 

 very minute punctiform flattened. Soiv. t. 372. f. 5. Fr. Syst, 

 Myc. V. 2. p. 481. El. 2. p. 98. Cryptosphceria Sillepunc- 

 tata, Grev. Fl. Ed, p. 360. Sc. Crypt. Fl. t. 201. S. popu- 

 Una, Pers. Ic. Pict. ^ 21./. 5, 6. 



On small branches of ash. Very common. — At first sight from the 

 smoothness of the branches on which it grows resembHng a Verrucaria, 



150. S. vibrdtilis, Fr. (su7iple sloe-branch Sphceria) ; scat- 

 tered, perithecia entire covered globoso-depressed even black, 

 ostiolum very minute latent. Fr. ! Scler. Suec.n. 315. Syst, 

 Myc. V, 2. p. 482. 



On dead branches of the sloe and other species of Primus. Glap- 

 thorn, Norths. Rev. M. J. Berkeley .—yihen the epidermis is stripped 

 off, and held to the light, it is found to be perforated by the minute 

 ostiola, though externally there is but a very slight indication of the 

 presence of the /?cr^Y/^ec^a. yl^a linear, appearing moniliforra from the 

 sporidia, being arranged in a single row.
