Chardon : Pyrenomycetes of Porto Rico

as L. diffusa. The spore measurements given by different au- 

 thorities vary. Ours, 26-33 x ii- t 4 seem to agree with those 

 of Arnaud (1) (figs. 4-6). 



Material examined: 



On Miconia prasina (Sw.) DC. Porto Rican fungi (Fink), No. 

 587, Rio Piedras, Dec. 2, 191 5; Cornell University Explorations 

 of Porto Rico (Whetzel & Olive), No. 665, Maricao, Mar. 23, 

 1916. 



Lembosia tenella Leveille, Ann. Sci. Nat. Ill (Bot.) 3: 58. 



1845. 



Lembosia Coccolobae Earle, N. Y. Bot. Gard. Bui. 3: 301, 302. 

 1903. 



Theissen (37) has examined a portion of Earle's type and says : 

 " Nach dem Blatt zu urteilen, ist die Matrix genau derselbe wie 

 die Nicaragua-Exemplar von Lembosia tenella; der Pilz ist der- 

 selbe, die Art also synosym mit der von uns adoptierten Form 

 von tenella" (figs. 7-8). 



The species seems to be of common occurrence. It is unique in 

 being able to withstand the most xerophytic conditions. The 

 spores measure 15-21 x 6-7 /x. 



Material examined: 



On Coccoloba uvifera (L.) Jacq. Plants of Porto Rico (Hel- 

 ler), No. 6375, Santurce, Jan. 7, 1903 {type) ; Cornell University 

 Explorations of Porto Rico (Whetzel & Olive), Nos. 522, 523, 

 Mayaguez, Mar. 3, 1916; id. id. (Chardon), No. 836, Ponce, 

 Sept. 6, 1920. 



Lembosia Dendrochili Leveille, Ann. Sci. Nat. Ill (Bot.) 3: 

 59- i845. 



Lembosia Agaves Earle, Muhlenbergia 1 : 15. 1900. 



A characteristic species on account of its numerous black spots, 

 which are slightly elevated. Earle's material is not fully matured, 

 and he gives the spore measurements as 14-16 x 6-7 fx. Ferdi- 

 nandsen and Winge (11) examined ripe material from Trinidad
