colourless fringe at mouth. Pycnospores at first colourless, then 

 greenish, and finally yellowish-brown, end cells often colourless, 

 ellipsoid, 5-septate and septa stout, 22-24 x 9-11 jx. Perithecia 

 simple, dark coloured but dark green when crushed, and walls 

 irregularly netted, with more or less globular or oval head, often 

 supported by stout body, papillate at apex when ripe and extrud- 

 ing plug of dirty yellow material, 170-280 x 90-156 /x or even 

 larger. Asci fusoid-clavate, sessile, apex rounded, 8-spored 

 (79 X 26 yx). Sporidia at first colourless, then pale green, finall}' 

 dark brown, oblong, constricted at the middle, 3-septate, and 

 usually longitudinalh^ divided, often in each division, 17-19 x 

 8-91;.. 



The various reproductive bodies are intermixed. Pale green 

 glomeruli (Heterohotrys) are also present.

Besides the gonidia, detached portions of the liypha probably 

 serve as such, and there are many-celled swollen bodies, between 

 the ordinaiy cells, which likely have the same function. The 

 spermogonia vary considerably in shape, but the rod-like spermatia 

 are very characteristic. The pycnidia are easily recognised by 

 their long and usually straight neck, composed of elongated 

 twisted filaments and reaching a length of 190/1, apart from the 

 body. The fringed mouth is in contrast to that of the perithe- 

 cium which is papillate and splits irregularly. The pycnospores 

 are at first unicellular and colourless, borne at the end of coloui"- 

 less, jointed filaments. They soon develop two or three septa 

 and become greenish, then finally turn brown ^on maturity, with 

 5 septa constantly. It is interesting to observe that the same 

 changes of colour are seen in the sporidia. There is a species of 

 Capnodium (C. aiistrale, Mont.) found in Australia on Conifers, 

 but it differs from this one in several important respects. The 

 perithecia are dichotomous, but here they are simple; the sporidia 

 are 4-5-septate and not constricted, but here they are 3-septate 

 and constricted.
