The colonies of this fungus are very inconspicuous, so much so that 

 in probably no case was the collection made for the Meliola; that is, in 

 nearly every case the leaves were collected for other fungi upon them, 

 chiefly Microthyriaceae, and it was only when the specimen came under 

 the compound microscope that the presence of the Meliola was recog- 

 nized. Indeed after it is known that the Meliola is present it is often 

 very difficult to locate the colonies amid the large numbers of other fungi 

 which are usually found upon these hosts. The fungus agrees fully with 

 authentic specimens received from Dr. Spegazzini. 



15. Meliola glabroides sp. nov. 



Colonies amphigenous, mostly epiphyllous, irregular, circular, 1-8 

 mm. in diam. Mycelium black, forming a loose network, 7)U, in diam- 

 eter, branches mostly opposite, often at right angles. 



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

 SOfi long, head cell ovoid, entire or angular, 17 x 14/x, the basal cell 7/a 

 long. Mucronate hyphopodia few, alternate or opposite, bottle-shaped, 

 16-18 X 6/x. Perithecial setae none. Mycelial setae none. 



Perithecia 100-140/^, rough with rounded protuberances. Asci soon 

 evanescent ; aseospores 4-septate, brown, very slightly constricted, obtuse, 

 41 X 17/x.
