 enclosed in the leaf.

Spores at first in balls up to 80;;. diameter, readily separating. 

 Spores spherical, olivaceous, smooth, 0[l diameter. In the 

 inflorescence, which it converts into a black mass enclosed 

 within the sheath.

Thecaphora inquinans B. & Br. 



This was described by Berkeley and Broome from specimens 

 on Paspalum scrobiculatum L., collected by Thwaites in 

 Dolosbage, May, 1868. Their description is : " Semina tota 

 implens ; sporis angulatis conglomeratis ; pedicelUs elongatis 

 pellucidis. Spores 3-7 together, -0004- -0007 (inches) across 

 collectively. Turning the whole contents of the seed iato a 

 black powder." In Grevillea, XVIII., p. 19, it is said to be 

 identical with Cerebella paspali Cke. & Mass. (Grev., XVI., 

 p. 20). In Saccardo, IX., p. 290, it is Usted as Cerebella 

 inquinans Cke. & Mass. 



The specimens at Kew are all of them Thwaites 588. The 

 mounted specimen from Herb. Berk, consists of three inflor- 

 escences, from which most of the fruits have disappeared, and 

 shows nothing, except in one spot where four fruits are bound 

 together by what appears to be a developing Cerebella. The 

 packet of duphcates from Herb, Berk, contains several 

 inflorescences which bear an undoubted Cerebella, well 

 developed but somewhat mouldy ; in addition there are 

 numerous detached fruits, but I was unable to find that any 

 of them contained a black powder. The co-type from Herb. 

 Cooke appears to be quite sound, without any fungus of any 

 description. Berkeley's drawing shows a piece of the stroma 

 of a Cerebella. 



Berkeley and Broome's description suggests that they had 

 before them the Sorosporium which has been listed above as 

 iSorosporium paspali McAlp. ; but there is nothing in the
