515] MELIOLA IN PORTO RICO — STEVENS A7 



62. Meliola chamaecristae Earle 



Bull. N. Y. Bot. Gard. 3 : 304, 1905. 



Described "on Chamaecrista glandulosa," collected by Heller, No. 

 6371. 



63. Meliola earlii sp. nov. 



Colonies amphigenous, irregular, 1-4 mm. in diam. Mycelium form- 

 ing a loose network of crooked threads which branch irregularly, often, 

 angling at the hyphopodia, about Q/x in diam. 



Capitate hyphopodia small, alternate, not crowded, about 25/jl 

 apart, ovoid or pyriform, sometimes angular or bent, 8 x 10;U., the basal 

 cell short. Mucronate hyphoodia few, bottle-shaped. Perithecial setae 

 none. 



Mycelial setae few or numerous, about 160/a long, straight or slightly 

 curved, opaque, tip acute. 



Perithecia 160/^, rough with rounded protuberances, ostiole none. 

 Asci soon evanescent ; ascospores 4-septate, brown, somewhat constricted,, 

 obtuse, 35-40 x 10/t. 

 On Pilea sp. Fig. 45. 



Florida Adentro, July 1, '15, 7685 (type). 

 On Pilea parietaria (L.) Bl. 



Rio Arecibo K. 64.7, July 8, '15, 7804. 

 On Pilea nummularifolia (Sw.) Wedd. 



Jajome Alto, Dec. 3, '13, 5640. 



The species is associated with a Meliola determined by Earle as M. 

 triloba on Pilea parietaria^ Heller, No. 558. It is differentiated from 

 M. leptospora by spore characters. This Meliola though associated with 

 M. triloba is clearly distinct from it in the general habit of the mycelium 

 and especially in the presence of mycelial setae on M. earlii. 



The species is named in honor of F. S. Earle in recognition of his 

 researches upon Porto Rican fungi. 



64. Meliola gesneriae sp. nov. 



Colonies hypophyllous, circular, 2-8 mm. in diam. Mycelium blacky 

 forming a close network, T/jC in diameter, branches mostly opposite. 



Capitate hyphopodia alternate, not crowded, 1 per cell, cells about 

 24;a long, head cell ovate to globular, 10 x 14fi, the basal cell 4-6/a long. 

 Mucronate hyphopodia alternate or opposite, bottle-shaped. Perithecial 

 setae none. Mycelial setae straight or slightly curved, 400 x 7/^, dark 

 throughout, most abundant around the perithecia. Tip acute. 



Perithecia 110/^, smooth. Asci soon evanescent; ascospores 4-septate^ 

 brown, very slightly constricted, 41 x 17/t.
