asci and some of which did not. An examination of the sections disclosed the 

 fact that, in certain regions of the hymenium, ascigerous hyphae do not develop. 

 In these places there is, therefore, only a very thin covering formed over the 

 bottom of the ascoma and a corresponding pit in the hymenial surface results. 

 The formation of a large number of these pits causes the honeycombed appear- 

 ance on the floor of older ascomata from which the asci have disappeared (figs. 

 9, lo). 



CoccoMYCES MUSAE (Lev.) Sacc. Syll. Fung. 8:752. 1889. 



On dead leaves of a cultivated species of Musa, Rio Maricao, above Mari- 

 cao, September 10, 1913, no. 3631 (fig. 7). 



With this, as with the preceding species, no exsiccati have been available 

 for comparison, and the current descriptions are not such as would make 

 possible an accurate determination. The fungus clearly belongs to the genus 

 Coccomyces, however, and its occurrence on Musa is regarded as being sufficient, 

 with other general superficial characters, to place it under the species already 

 described for that host. Since, however, the previous description is so meager, 

 an emended specific description is here given. 



Spots amphigenous, v^^hitish or straw-colored, roundish, 5-10 

 mm. in diameter, frequently confluent, uniformly but sparsely 

 dotted with ascomata. Ascomata punctiform, black, 350-750 n 

 in diameter, rupturing irregularly by a 3 or 4-partite radial cleft. 

 Asci cylindrical, short-stipitate, 55-90X10-12 m, 8-spored; asco- 

 spores long, rodlike, with obtuse ends, 50-70X3 M, hyaline and 

 multiseptate at maturity. Paraphyses long, filamentous, numer- 

 ous, exceeding the asci, hyaline. 



Meliola Fries 



The following species constitute a few that were overlooked, 

 either because of their resemblance to other fungi, or because of 

 their inevidence on a host collected for the sake of other fungi upon 

 it, when the monograph of Porto Rican Meliolas was compiled by 

 Dr. Stevens.^ 



Meliola conferta, sp. nov.— Spots amphigenous, irregularly 

 circular, punctiform, 0.5-1 mm. in diameter. Mycelium brown, 

 densely compacted, radiate, branches opposite, filaments 8 a^ in 

 diameter.
