Description of the Engravings. 



Fig. 1. Asci and sporidia of Scorias spongiosa, Fr., magnified 600 dia- 

 meters. From a sketch by Dr. Montagne. 



Fig. 2. Capnodium Fuligo, B. and D. Peridia, mycelium, and sporidia 

 highly magnified. From a sketch by Mr. Broome. The threads of the 

 mycelium to the right of the figure are evidently connected by their 

 gelatinous integument. 



Fig. 3. Capnodiuvi Schwe.initzii, B. and D. Flocci of mycelium and spo- 

 ridia, both highly magnified. 



Fig. 4. Capnodium salicimivi, Mont. Asci with immature sporidia, and 

 mature sporidia from the absorbed asci, magnified 380 diameters. 

 From a sketch by Dr. Montagne, 



Fig. 5. Capnodiuvi elongatum, B. and D., with young and mature sporidia 

 more or less highly magnified. From a sketch by Mr. Broome. 



Fig. 6. Capnodium. Persoonii, B. and D. The peridium is in this case ruptured 

 horizontally, but this is by no means constant. The endochrome of the 

 joints of the mycelium is frequently bipartite. Portions of the mycelium 

 which have been accidentally detached are growing on the hairs of the 

 matrix. From a sketch by Mr. Broome. 



Fig. 7. Capnodium Caroliniense, B. and D. Outline of group of peridia and 

 sporidia highly magnified. 



Fig. 8. Capnodium expansum, B. and D. Sporidia highly magnified. From 

 a sketch by Mr. Broome. 



Fig. 9. Capnodium australe, Mont. Outline of branched peridia ; a single 

 peridium crushed and discharging its asci ; young ascus, mature ascus 

 with sporidia, and portion of mycelium, all more or less highly mag- 

 nified. 



Fig. 10. Capnodium Footii, B. and D. Peridia and mature mycelium, from 

 Mercurialis perennis. Sketched by Mr. Broome. 



Fig. 10*. Immature mycelium, from the same species growing on laurel. 



Fig. 11. Glenospora Ciirtisii, B. and D. Portion of plant, showing the 

 fascicles of threads with their fi-uctifying branches ; a portion of the 

 fructifying threads separated from the fascicles, and a single spore, more 

 or less highly magnified.
