58-85 X 18-27 n. Paraphyses filiform. Spores 9-19 X 7-1 2 fx, hya- 

 line, continuous. — Fig. 14. 



On Mayepea domingensis: Maricao, 785 (type), 775, 731, 765, 4751, 196, 

 8787, 4720; Mayaguez Mesa, 7471, 7585; Coamo, 148. 



The circular tan-colored spots with numerous punctiform stromata are 

 characteristic. 



Phyllachora metastelmae, sp. nov. — Stromata shining black, 

 1-2 mm. wide, 5-15 mm. long, partially encircling the stem, 

 occupying all of the tissues exterior to the wood. Locules about 

 200 ju in diameter, 120 ju high. Asci 8-spored. Spores cylindrical, 

 hyaline, continuous, 14X5 m- — Figs. 15 and 16. 



On stems of Metastelma sp.: El Alto de le Bandera, 8715 (type). 



Phyllachora nectandrae, sp. nov. — Spots round or irregular, 

 brown, surrounding the stromata, showing on both sides of leaf. 

 Stromata epiphyllous, black, shining, 1-4 mm. in diameter, slightly 

 raised, scattered or seldom confluent. Locules single or few, nearly 

 globular, located in the mesophyll, 225-500 ju wide, 300 )u deep, 

 side wall thin. Clypeus black, 40-50 ju thick, extending laterally 

 beyond the locules. Paraphyses copious, filiform. Asci cylindri- 

 cal, 8-spored, 108 X 10 /x. Spores oblong, 14X5 ju- — Figs. 23 and 24. 



On Nedandra patens: Maricao, 3608 (type), 8949, 3435, 3730. 

 Differs from P. nectandricola Speg. in having paraphyses and in other 

 details. 



Phyllachora ocoteicola, sp. nov. — ^Spots amphigenous, abundant, 

 angular, 2-4 mm. across; above shining black, below smooth, 

 dull black, with minute hillocks indicating the locules. Clypeus 

 epidermal, apparent both above and below, flat, about 17 /x thick. 

 Stroma of mesophyll consisting merely of scattered mycelial 

 threads. Locules several to the spot, median in the mesophyll, 

 156-170 n high, 200-235 M wide, internal dimensions, wall hyaline, 

 thin. Asci numerous, 8-spored. Spores oblong to cylindrical, 

 17X54 Ml often somewhat pointed at one end. Paraphyses 

 numerous, filiform, crooked. — Figs. 25 and 26. 



On Ocotea leucoxylon: Monte Alegrillo, 4768 (type), 4767, 4725; Monte 

 de Oro, 5669; Maricao, 701. 



Quite distinct from P. ocoteae P. Henn. in shape and character of spot, 

 size of spores, and in other details.
