The following fungi were collected by Mr. A. A. Heller in 

 Porto Rico during January' and Februar}^, 1900 : 



MICROTHYRIACEAE 



MiCROTHYRiUM Lagunculariae Wint. ? 



The specimens are immature, no spores being developed, 

 hence the determination is tentative only. 



On living leaves of Laguncularia racemosa^ Mayaguez, 

 altitude 10 feet. Januar}^ No. 4361. 



PERISPORIACEAE 



Apiosporium sp. 



As no perithecia were developed, the species could not be 

 determined. 



On Eugenia Jambosa. January. No. 4428. 



Meliola glabra Berk. & Curt. 



On upper surface of leaves of Piper aduncum^ two miles 

 southeast of Mayaguez, altitude 400 feet. January. No. 4359a 

 (with Cercospora Portoricensis). 



On Sauvagesia erecta^ fourteen miles southeast of Maya- 

 guez, altitude 1000 feet. January. No. 4480. 



Mellola Iponioeae sp. nov. 



Epiphyllous, covering small, imm., irregularly rounded, 

 seldom confluent, brown spots: mycelium rather scanty, threads 

 much branched, slender, about 7-", septate at inten-als of 15-25/^: 

 capitate hyphopodia abundant, small, 16-20^ long, regular, head 

 cell globular, 10-12^, basal cell very- short 4-8x6-7^, attached at 

 an acute angle: setae abundant, straight or abruptly bent at 

 base, slender, fuscous, frequently septate, tips obtuse, entire, sub-
