(Concluded from p. 193.) 



234. Hendersonia tarda sp. n. 



Pycnidiis amphigeiiis, saBpius epiphyllis, spcarsis, globosis, poro 

 pcrtusis, non p[ipillatis, opidermide supra porum perforata, 220- 

 250 /i diam. ; contextu plectenchymatico, subolivaceo. Sporulis 

 anguste elliptico-oblongis, junioribus utrinque acutatis, dein ro- 

 tuudatis, dilute olivaceis, diutissime 1-septatis, 8-12 fj. long., 

 absolute maturis 3-septatis, 15-16 x 2| /x. (Tab. 543, fig. 5.)

The spores are held together when young in a clear-olive muci- 

 laginous mass, but singly are very pale ; at first they are lanceolate- 

 fusiform and eseptate, then for a long time 1-septate, but ulti- 

 mately a few show two septa and still fewer three septa. 



235. Hendersonia mollis sp. n. 



Pycnidiis lineatim inter costas vaginae seriatis, immersis, ca. 

 300 1^1 diam., depresso-sphaericis, nigrescentibus, epidermidem 

 perforantibus, labecula brunneola cinctis ; contextu mollisimo 

 parenchymatico pallide ochraceo. Sporulis fusoideo-cylindricis, 

 obtusiusculis, altero apice subattenuatis, 38-42 x 4-5 /x, primitus 

 hyalinis, dein brunueolis guttulatisque, demum olivaceo-brun- 

 neolis v. flavescentibus, tenuiter sed distincte 6-7-septatis, cellula 

 utraque guttulis minutissimis utrinque ad septa priedita ; sporo- 

 phoris brevissimis (?). (Tab. 543, fig. 4).

The mature spores were almost uniformly provided with seven 

 delicate, but unmistakable septa, with one or two minute guttules 

 on each side of the septum. The species is alhed to H. riparia Sacc, 

 but no distinct sporophores could be seen. It might also be near 

 to H. intermixta Cooke [Stagonosjjora Sacc), the pycnidiaof which 

 are not described. The spores agree also with the description of 

 those of Wojiiowicia hirta Sacc (Syll. xiv, 960), but the pycnidia 

 are different.

DiPSACI. 



Pycnidia subglobose-depressed, showing through the thin 

 epidermis, which is pierced, 100-140 /x diam., black ; texture thin, 

 yellowish-fuscous. Spores cylindrical or faintly clavate, mostly 

 curvulous or flexuous, very pale olivaceous, mostly 3-soptate, not 

 constricted, 23-26 x 11-2 /x. 



On dead stems of Dipsacits silucstris, Credonhill Camp, 



Hereford, June. This form differs from the species especially in 



its narrower spores, in which it resembles Saccardo's variety 



muralis (sp. 20-25 x 2-3 /a) ; the septa are very delicate, and the
