IMPERFECT CAPSULAR FUNGI— SPHAEROPSIDEAE 275 



myxa, in like manner, corresponds to Myxosporium, growing on 

 dead branches, but with uniseptate sporules. 



The section Phragmosporae includes such species as have 

 sporules with two or more septa, whether hyaline or coloured ; 

 and thus we have two subsections, the Phaoeophragmiae and 

 the Syalophragmiae. In the former Stilbospora is the ana- 

 logue of Melanconium and Didymosporium, with sporules soon 

 oozing out and blackening the orifice;' whilst Coryneum forms 

 compact pustules, in which the sporules are for a long time 

 attached to their pedicels, and do not ooze out and blacken the 

 matrix. In habit the species are more pulvinate and erumpent, 

 being held together almost as compactly as if enclosed in a 

 perithecium. Scolecosporium resembles Coryneum, but the 

 sporules are beaked at the apex. Asterosporium has more the 

 habit of Stilbospora, but the sporules are compound, or rather 

 triradiate, resembling three sporules of Stilbospora grown to- 

 gether at the base and diverging above in three rays on the 

 same plane. In another genus, Seiridium, the septate brown 

 sporules are united to each other by a hyaline isthmus, so as 

 to form a chain. The two remaining genera, having ciliate 

 sporules, are Hyaloceras, in which the 

 multiseptate brown sporules have a single 

 curved awn at each extremity ; and Pes- 

 talozzia, in which the sporules are crested 

 by one or more hyaline cilia, which are 

 usually divergent when more than one, 

 and the central cells of the sporules are 

 commonly coloured (Fig. 125). The 

 Syalophragmiae includes but three genera; 

 that of Bhopalidium, with one little-known FlG - i25.-Spomies of 

 species, has clavate, multiseptate, hyaline 

 sporules, aggregated in little innate brown pustules on the 

 leaves of plants; and Septoglaeum, which is practically 

 Gloeosporium, or Marsonia, with more than one septum to 

 the sporules. The remaining genus is Prosthemiella, which is 

 the analogue of Prosthemium, but without a perithecium, 

 and the stellate sporules are hyaline. It will facilitate 

 determination to remember the instances, which are so con- 

 stantly recurring, in which Fungi possessing the same habit
