This specimen (Herb. Berk. no. 3191!), from South Carolina, 

 is Pliomopsis depressa, Tray., not Phoma syringica, Thiim. It 

 has biguttulate fusoid spores, 7-9 x 2-2-5 fi. 



490. Phoma Limonis, Thiim. 



This is represented in Herb. Kew by a specimen from de 

 Thiiinen (Gorizia, Mycoth. tuiiv. no. 1193!), on which there 

 are at least four apparently different minute fungi (one of them 

 Metasphaeria papulosa, Sacc); but none of them agrees with the 

 description of the Phoma* 



533. Phoma macropus, Beth. $Curt. 



On an unknown host (New England, Sprague, Herb. Berk. 

 no. 5695 !). The external appearance resembles Berkeley's 

 description, but no spores or sporophores such as he assigns to 

 it, nor any others, could be found. This species should be 

 deleted. 



551. Phoma tamaricella, Sarr. 



There cannot be the slightest doubt, after examination of the 

 specimens, that this is merely the same as P. tamariciiui, Thiim. 



558. Phoma stictina, Sacc. 



Coccularia stictica, Berk, in Grevill. 1874, ii. 97. 



Represented by two exsiccata (Herb. Berk. nos. 1532! and 

 2235!). On these nothing is apparent but nodular subsclerotial 

 mycelial growths. 



559. Phoma sphaerospora, Sacc. 



On this specimen (Rouin. Fung. Gall. no. 3969!), on samarae 

 (not branches) of Ailanthus, nothing is visible but knots of 

 mycelium and various other stages of a Pleospora (not P. 

 herbarum). 



, 561. Phoma ailanthina, Thiim. 



On examining Thiim. Mycoth. unic. no. 989! there could be 

 found only a species of Coniothyriam, with a small quantity of 

 another (undeterminable) fungus. Those species of Coniothy- 

 rium which have nearly colourless spores when young have often 

 been mistaken for a Phoma % as here. 





IX.— THE TRUE MAHOGANIES. 



E. A. KOLFE. 



Of late years extensive planting of Mahogany trees has taken 

 place in Trinidad and some other colonies, and numerous speci- 

 mens and fruits have been received at Kew with the enquiry 

 as to whether they represent the true plant. Mahogany had
