215. Leptosph^ria Fuckelii Niessl in Voss, Zwei neue As- 

 com. p. 1. Sacc. Syll. ii, 71. 



Perithecia single or a few arranged in a line, in the latter case 

 erumpent by a fissure, subglobose, black, with a short ostiole ; 

 texture angular-parenchymatous, olivaceous-fuscous. Asci sub- 

 clavate-cylindrical, rounded above, very shortly pedicellate, about 

 110 X 11 /x, surrounded by numerous, filiform, plainly articulate 

 paraphyses, 3 /x wide and a little longer than the asci. Sporidia 

 distichous, cylindrical or slightly tapering downwards, straight or 

 more often slightly curved, 5-septate, yellowish, the fourth loculus 

 from the apex protuberant, 28-32 x 4^-51 /x. (Tab. 512, fig. 1.) 



On the lower part of old culms of Phalaris arundinacea varie- 

 gata, in a garden, Burcot, near Bromsgrove (Ws.), May. The 

 perithecia were found especially near the nodes. The last-formed 

 septum of the spore is the second from the top ; it is this which 

 gives the peculiar character to the species. Accompanying the 

 Leptos2:)hcBria was a Phoma.

 Var. ciRSiicoLA v. nov. 



Peritheciis gregariis v. seriatis, prime epidermide ostiolo 

 papillate perforata velatis, dein epidermide corticeque excussis 

 denudatis, depresso-sphgericis, atris, undique ostiolo excepto pilis 

 copiosis rigidis radiantibus septatis olivaceo-nigricantibus obsessis, 

 pihs sursum pallidioribus, 200-300 x 3 /x. Ascis clavatis, breviter 

 crasseque pedicellatis, 80-100 x 10-14 /x, paraphysibus copiosis 

 hyalinis fihformibus, ca. 1 ^a cr., pluriguttulatis obvallatis ; sporidiis 

 tristichis, fusoideis, flavidis, 8-10-septatis, 45-56 x 3-4 /x, loculis 

 uni- V. bi-guttulatis, loculo tertio v. quarto inflate.

The whole perithecium reminds one somewhat of a dry closed 

 Vermicularia, about | mm. broad. There can be little doubt that 

 this variety belongs to the species figured by Currey (Simj^le 

 S'plicErice, fig. 129) ; the spores are exactly the same except that 

 they are a little longer. They are so closely clustered together in 

 the ascus that, until they are extruded, one might almost think 

 that they were those of Ophioholus acwyiinatits, which the peri- 

 thecia resemble as well until the epidermis is removed. There 

 appears then a likeness to 0. Cirsii, which is also beset with 

 filaments at its base, but the spores are very different in shape 

 and only half as long.
