possibly be something analogous to the phsenomena exhibited by 

 Vesiculifera. 

 Plate XI. fig. 30. Sporidium highly magnified. 



645. S. (Caulicolse) commanipula, n. s. Sparsa primum sub- 

 globosa tecta demum denudata collapsa ostiolo minuto; ascis 

 cylindricis ; sporidiis biseriatis brevibus elllptico-cymbiformibus 

 uniseptatis. On the dry capsules of some Scrophularittj Glen 

 Isla, Forfarshire, May 1846, Mr. W. Gardiner. 



Scattered, at first covered by the cuticle, subglobose, then ex- 

 posed and collapsed, with a minute papillseform ostiolum, which 

 is however sometimes obscure. Asci cylindrical; sporidia bi- 

 seriate, elliptico-cymbiform, uniseptate. Sometimes one of the 

 endochromes is decidedly conical, with a constriction about the 

 centre. 



This occurs on the capsules of the same plant whose stems 

 produced S, modesta. On the capsules we also find a Phoma, 

 precisely similar externally, which may be regarded possibly as 

 the Sphseropsoid form of the species. 



Plate XL fig. 31. a. Ascus; b. sporidia: both more or less magnified. 



646. S. (Caulicolse) Thwaitesii, n. s. Peritheciis minutis con- 

 vexis basi applanatis ; mycelio subtilissimo matricem intrante 

 seruginoso; ascis cylindricis; sporidiis oblongo-clavatis curvulis 

 obtusis ; endochromatibus 4 repletis. On stems of Umbelliferce, 

 Leigh Wood, Bristol, G. H. K. Thwaites, Jan. 1845. 



Perithecia minute, convex above, flattened below, arranged in 

 short lines ; seated on the woody fibres, which are traversed and 

 covered with very delicate anastomosing, verdigris-green threads. 

 Asci cylindrical or subclavate, rather short; sporidia biseriate, 

 oblongo-clavate, obtuse at either extremity, slightly curved, con- 

 taining about four endochromes. In some specimens we find 

 naked, oblong, slightly curved spores, with about five endo- 

 chromes, the whole gelatinous mass having a pale sea-green tint. 



The seruginous threads running through the hyaline woody 

 fibres and anastomosing in their cavity form a very pretty 

 object under the microscope. 



On the same stem a Peziza occurs, externally resembling P. 

 atrata, but with elongated, oblong, curved sporidia, containing 

 7-9 endochromes. 



Plate XI. fig. 32. a. Sporidia; h. mycelium ; c. one of the woody cells 

 traversed by mycelium. All more or less magnified. 



647. S, (Caulicolse) Phomatospora, n. s. Immersa; peritheciis 

 depressis ellipsoideis ostiolo papillseformi ; ascis linearibus ; spo- 

 ridiis uniseriatis oblongo- ellipticis minutis hyalinis binucleatis. 

 On dead potato stalks. Ash wick, Gloucestershire, March 1850.
