NOTE ON PEZIZA FUSCESCEN8. 189 



species " Ce joli petit champignon a des rapports avec le P. fusccs- 

 cens, Pers." (Ann. des Sc. Nat. vol. xvii., 1842). Desmazieres saw 

 that the hymenium of the plant he found growing on oak leaves 

 presented the unusual character of possessing paraphyses as broad, 

 or nearly as broad, as the asci, and far exceeding them in length, 

 tapering to a sharp point as represented in fig. 184, p. xli., and 

 fig. 2, p. xlii. of this vol., whereas in F. fuscescens, Pers., this pecu- 

 liarity is not to be seen.* A figure of the last named species is 

 given on PL xl. (fig. 154) by the editor of " Grevillea" without such 

 paraphyses. Fuckel is entirely silent about them in his description 

 of this species (Sym. Myc. p. 309), and after a careful examination 

 of my South Wales specimens I find no indication of their exis- 

 tence. I conclude, therefore, that Desmazieres considered the 

 presence of these peculiar paraphyses in the hymenium of his 

 oakleaf plant a sufficient reason for distinguishing it as a new 

 species under the name of P. brunneola. 



PODISOMA ON JUNIPERUS PHCENICIA. 



In a communication on the species of Podisoma, published in 

 the " Quekett Journal " (vol. ii., p. 255), we indicated that some 

 doubts existed as to the species found at Naples by Gasparrini on 

 Juniperus phcenicia, and figured by him under the name of 

 Podisoma fuscum. Messrs. Tulasne, in their memoir on the Tre- 

 mellini, alluded to this species in a note, remarking that if the 

 figures were accurate this coixld not be the Podisoma fuscum of 

 Corda, and was probably a new species. Recently we have 

 received specimens of a Podisoma on Juniperus phcenicia, collected 

 by M. Roux in the vicinity of Marseilles, the features of which 

 differ somewhat from the Podisoma Juniperi communis. Fries. 

 The stroma is ligulate, slender, and elongated, and there is 

 scarcely any perceptible swelling of the matrix, but the principal 

 difference exists in the pseudospores. In the form which is com- 

 monly found on Juniperus communis the pseudospores are more or 

 less rounded at the apex, and scarcely, if at all, constricted at the 

 commissure ; in the form on Juniperus phoe7iicia both cells are, as 

 nearly as possible, equal in size and form, both attenuated up- 

 wards, and both swollen at the base, so that the pseudospores are 

 strongly constricted at the septum. This accords almost as little 

 with Gasparrini's figures as the typical form oi Podisoma Juniperi- 

 communis, and could scarcely be referred to his species more than 

 the latter. The question naturally arises whether the form on 

 Juniperus phcenicia can be regarded as distinct from that on 



* Similar paraphyses are found in P. ScJvweinitzii (Behm. exs. 156) P. 

 Sjahcerocepluda, Wallr., and P. palearum, Deam.
