II 



collapsing, obscurely ostiolate, composed of somewhat regularly 

 hexagonal cells about i2/^ in diameter: asci broadly oval, usually 

 4-spored, soon evanescent: ascospores compressed, oval as seen 

 in broader aspect, cylindrical and sometimes slightly curved as 

 seen from the side, ends obtusely rounded, about equally 4 sep- 

 tate, scarcely if at all constricted, the fourth cell often slightly 

 enlarged, fusco-olivaceous, sub-transparent, about 35x14x8/^.

Meliola Liagunculariae sp. nov. 



Amphigenous, forming black, orbicular spots 3-5mm. in 

 diameter, or more often widely effused: mycelial threads slen- 

 der, 4-6^, obscurely and rather distantly septate, scattered, not 

 crowded, forming a thin closely adhering pellicle: capitate hy- 

 phopodia distant, alternate, divaricate, small, slender, about 12- 

 1 6/^ long, head cell oblong or narrowly obovate, usually rounded, 

 occasionally somewhat irregular, 8-12x6-7/": mucronate hypho- 

 podia occasional, alternate or opposite, slender, about i6x4,«, 

 tapering regularly upward but the top blunt or truncate; setae 

 none: perithecia scattered, globose, not collapsing, about 150^, 

 ostiolum not observed, surface conspicuously roughened by chit- 

 inized conical projections (as in M. glabra B. & C), about 12^ 

 at base by 8-1 2/" high: asci soon evanescent, not observed: asco- 

 spores small, oval, light fuscous, about equally 4 septate, ends 

 rounded, about 32x12^. 



This is evidently closely related to Meliola glabra B. & C, 

 with which it agrees almost exactly in the roughened exterior 

 of the perithecium, but it is easily distinguished by the more 

 widely effused, very slender mycelium, and by the small, slen- 

 der hyphopodia. The spores too are smaller.
