MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPH^.RIyE. 271 



79. S. (Diatrype) aspera, Fr. S. M. ii. p. 354. The only difference between the fructifi- 

 cation of these plants and that of S. verriicceformis is that their sporidia are somewhat 

 smaller and without nuclei, and their asci are clavate, not fusiform. 



80. S. (Diatrype) stigma, Hoffm. ; Fr. S. M. ii. p. 350. Tab. XLVI. fig. 82, sporidia, x 

 450. Sporidia yellowish in the mass, almost colourless when single, slightly curved, 

 0-0004 inch long. 



81. S. (Diatrype) bullata, Ehr. ; Fr. S. M. ii. p. 349. Sporidia just like those of S. 

 platystoma (see fig. 66), 0-0002 to 0-0003 inch long. 



82. S. UNDULATA, Pcrs. ; Fr. S. M. ii. p. 350. Sporidia biseriate, yellowish, slightly 

 cm-ved, rounded at each end, 0-0004 inch long. The perithecia break through 



. the bark in an undulating manner. The sporidia are just like those of Spharia 

 stigma (see fig. 82), of which this species is probably only a variety, as was long 

 since remarked by Fries. 



83. S. (Hypocrea) LENTA, Todc ; Fr. S. M. ii. p. 349. Tab. XLVI. fig. 83, ascus with spo- 

 ridia, X 325. The fructification of this plant is precisely similar to that of S. rufa ; 

 and I would refer to the remarks appended to that plant. The square-shaped, irregu- 

 lar, colom-less sporidia, after escaping from the ascus, become round or nearly so, their 

 average diameter being less than 0-0002 inch. I have retained the plant in this 

 division, as it is so arranged in the Herbarium, and by Fries in the ' Syst. Myc' 

 In the ' Suroma Veg. Scandinavige ' it is placed (strange to say) in the genus Diatrype ; 

 according to the arrangement in that work, it ought certainly to be a Hypocrea. 



Div. 7. Versatiles. 



84. S. (Diatrype) scabrosa. Dec; Fr. S. M. ii. p. 360. Tab. XLVI. fig. 84, ascus with spo- 

 ridia and free sporidia, X 450. Sporidi-a, uniseriate, clear brown (one had a hyaline tip 

 at each end), subcylindi-ical, rounded at each end, triseptate, slightly constricted at the 

 septa, 0-0006 inch long. In this specimen the perithecia are very slightly immersed, 

 and look like large specimens of Sphceria piilvis-pyrms, which, although belonging 

 to the Denudatse, is often subcuticular in its growth. The fruit also is the same as 

 in S. pulvis-pyrius, except as regards size. The plant, however, being marked /S". sca- 

 brosa by Mr. Berkeley, I have described it as such, but with some doubt. 



85. S. (Diatrype) podoides, Pers. Syn. p. 22, excl. syn. Tab. XLVI. fig. 85, ascus Avith 

 sporidia and free sporidia, x 225. Sporidia biseriate or crowded, clear, rather pale- 

 brown, 7-septate, with a hyaline joint at each extremity, often slightly curved, 0-0024 

 to 0-003 inch long. Quite distinct from >S'. scabrosa, Dec, under which it was placed 

 by Fries as a variety. 



86. S. PODOIDES, var. l^vis, does not differ from the above, as far as the fruit is concerned, 

 but only in the smoothness of the tubercles, arising from the ostiola of the perithecia 

 not penetrating the stroma. 



87. S. (Diatrype ?) petiginosa, Fr. in Utt. Tab. XLVI. fig. 86, ascus Avith sporidia and 

 free sporidia, X 450. Sporidia biseriate or crowded, yellowish, rounded at each end, 

 narrow, slightly curved, 0-0004 to 0-0006 inch long. 



88. S. Piatbype) leprosa, Pers. ; Fr. S. M. ii. p. 365. Tab. XLVI. fig. 87, ascus with
