Hysterostomella Floridana sp. nov. 



Epiphyllous, scattered, spots none ; stromata black, superficial, 

 crust-like, 1-4 mm. in diameter, the margin sterile and smooth, 

 the central portion rugose with irregular elongated ridges formed 

 by the connivent lips of the poorly defined subconfluent ascomata, 

 the margin bordered by a narrow indistinct, Lem&osia-like subic- 

 ulum of anastomosing fuscus threads : asci broadly oval, apara- 

 physate, rather thick-walled, 30-35 x 20-25/*; ascospores eight, 

 inordinate, narrowly ovate, about equally uniseptate, constricted, 

 ends obtuse or the narrower one subacute, hyaline to light oliva- 

 ceous (probably darker with age), 16-18 x 6-7/1.

The five previously described species of this little-known trop- 

 ical genus are all from South America. It is evidently closely 

 related to Lembosia from which it can only be separated by the 

 compound stroma-like ascoma. 



This peculiar group of black, superficial, mostly tropical fungi 

 has always been classed in the Hysteriales on account of their 

 elongated ascomata that open by a slit. This seems to be only a 

 superficial resemblance, their real affinity as indicated by mode of 

 growth, structure of the ascoma and characters of spores and ascj 

 being- much closer to the Microthvriaceae.

Hysterostomella sabalicola sp. nov. 



Hypophyllous, scattered on small, irregular, yellow spots ; 

 stromata black, scutellate, small, irregularly oval, .75-1 mm. in 

 diameter, sterile margin narrow, 50 fi, of compacted parallel ra- 

 diating threads, subiculum none, central portion elevated and rugose 

 from the long, irregular connivent lips of the poorly defined asco- 

 mata : asci oval, about 40-50 X 20 ft; ascospores eight, 

 nate, equally uniseptate, nearly hyaline (perhaps young), about 

 20 x 6 //.

Lembosia brevis sp. nov. 



Epiphyllous on irregular brownish spots 2-4 mm. in diameter ; 

 ascomata thickly scattered black, crust-like, usually simple and 

 distinct, but occasionally forking or sparingly confluent, very short, 

 ends obtuse, 100-175 x 70-80 ,«, subiculum reduced to a fringe of
