212 PROCEEDINGS OP THE AMERICAN ACADExMY 



is a summary of the author's remarks on the anatomy of these species. 

 H. Indlca occurs on the pods of an Indian sj^ecies of Acacia; the 

 clusters of heads upon one side of the pod are represented by corre- 

 sponding clusters on the opposite side. Upon careful examination, the 

 head of R. Indica is seen to " consist of a large, umbrella-shaped dark 

 cap," the spore-mass, " often 250 ^^ ^^ ^^^^^ across, composed of a 

 number of closely packed cells, supported by a long, hyaline, delicate, 

 and apparently compound stem, round the top of which is suspended a 

 circle of elongate hyaline bodies," the cyst-cells. In R. glandidosa, 

 the South Carolinian species, the stem is shorter than in R. Indica, 

 and the hyaline bodies at the top of the stem are fused firmly together 

 into a single mass, the cyst region. Two figures of each species 

 accompany the text, and serve to illustrate the remarks already noted. 



In his "Introduction to Cryptogamic Botany," p. 323, 1857, the 

 Rev. Mr. Berkeley places Ravenelia in the Cceomacei, and states that 

 " the spore," i. e. spore-mass, " is in this case of considerable size, and 

 evidently reticulate, and below it, either free or in contact with the 

 stem, is a circle of colorless bags, foreshadowing a more complicated 

 system of articulation than even in the following group," Puccinicei. 

 On page 305 are two figures, one of R. Indica and the other of R. 

 glandulcEfurmis, Berk, and Curt. (=: the former R. glandidosa, Berk, 

 and Curt.), both essentially like those of the previous paper. 



In 1873, Messrs. Berkeley and Broome jiresented to the Linnean 

 Society for publication the second part of their " Enumeration of the 

 Fungi of Ceylon," * and on page 93 of their paper five species of ^a- 

 venelia are described. The term pseudospore is here made to replace 

 that of spore, as applied to the spore-mass. R. Indica is redescribed, 

 and its cyst-cells are figured as having filiform j^rocesses extending 

 from their centres back into the depths of the head. These are called 

 "glandular stipitate bodies." R. sessilis, Berk., and R. acideifera, 

 Berk., are described as new. R. macrocystis, Berk, and Br., and R. 

 stictica, Berk, and Br., also new species, are figured with a frill of my- 

 celium-like threads, replacing in position the irregular line of the rup- 

 tured cyst-cells at the base of R. sessilis. The outer surface of the 

 spore-mass of ^. stictica is figured and described as slightly echinate. 



The latest paper touching upon Ravenelia is that by Mr. M. C. 

 Cooke.f In it all the species of the genus are described, with this
