= Namaspora alba Pr., which also occurs, in Germany, on Corylus. 

 Saccardo's record of F. glceosporoidcs is on Betula (?) in the 

 Ardennes. 



226. FusicoccuM quericinum Sacc. Syll. iii, 248. 



Stromata ohlong-conical, some transversely placed, inflating the 

 periderm, which at length splits and exposes a pale CytosiJora-\\kQ 

 disc ; contents pale rosy-ochre, without the slightest tinge of hlack 

 or olivaceous, surrounded (under the hark, as is seen when it is 

 stripped off) by a whitish zone. Spores very numerous, cylindric- 

 fusiform, acute at both ends, very slightly curved, colourless, 

 13-16 X 2|-3 /x ; the protoplasm is sometimes bipartite in the 

 middle, at other times biguttulate. (Tab. 542, fig. 6.) 



On twigs of Oak, near Malvern (J. W. EUis), May. Supposed 

 to be the pycnidia of Diajjorthe leijjhemia. Of. CryptosiJorium 

 conicum Bon. (Sacc. Syll. iii. 741), which seems to be very similar. 



227. Cytospora stictostoma sp. n. 



Stromatibus dense in ramulis gregariis, peridermio innatis, 

 \-\ mm. diam., pustulatis, protuberantibus, e basi rotundata 

 conicis, pseudolocellatis, contextu subceraceo atro-cinereo, disco 

 truncato emergente albido-furfuraceo, vulgo poro atro unico 

 centrali perforato. Sporulis oblongis v. subovoides, 7-9 x 2-2| /x, 

 e fronte visis praesertim basi subacutatis, vulgo biguttulatis, e latere 

 curvulis et obtusatis, sporophoris stipatis subulatis ad 15 /x long, 

 suffultis. 



Hah. in ramulis Pyri mali, Bristol, socia Diaporthe sticto- 

 stoma Sacc. (see no. 214). The spores of this species are very 

 unusual for a Cytospora ; the difference betw^een the face and 

 profile views is considerable. 



228. Ceuthospora Euonymi sp. n. 



Stromatibus amphigenis, dimorphis, (1) unilocularibus, (2) 

 plurilocularibus : (1) Minoribus, ca. J mm. diam., aggregatis v. 

 subsparsis, globulosis, prominulis, atris, ore conico-truncato epi- 

 dermidis laciniis cincto dehiscentibus ; disco furfuraceo rufo-fusco 

 v. dilute rubescente, quinetiam rubro. (2) Majoribus tardioribus, 

 sparsis, applanatis, orbicularibus, discoideis, |-| mm. diam., atris, 

 nitidulis, diu solidis sterilibusque, denique poris conico-truncatis 

 1-3 (rarius 4) dehiscentibus ; disco tandem sporis copiose expulsis 

 obliterato. Sporulis homomorphis, cylindricis, rectissimis, utrinque 

 obtusatis v. basi subattenuatis, perfecte hyalinis eguttulatisque, 

 14-17 X 2-2^ yu,, sporophoris rectis, tenuibus, sub£Equilongis 

 suffultis. (Tab. 543, fig. 1.) 



Hah. in foliis ramulisque Euonymi japonici. Wallasey, 

 Cheshire, September-December (Miss B. O'Loughlin, comm. 

 J. W. ElHs). Southampton, March (J. F. Kayner, comm. A. D. 

 Cotton). 



The two forms of conceptacles stand to each other exactly in 

 the same relation as Cytospora Laurocerasi Fckl. to Ceuthospora 

 Lauri Grev., which should equally be regarded as one species. 

 The larger conceptacles resemble perfectly those of Ceut}iosp)ora 

 phacidioides Grev. but are distinguished by the usually more
