NEW INDO-MALAYAN LABOULBENIALES. 45 



Laboulbenia Grylli nov. sp. 



Basal cell of the receptacle hyaline without a blackened foot, twice 

 as long as broad, its base abruptly rounded and penetrating the host 

 by a simple rhizoidal filament, the subbasal cell abruptly slightly 

 broader above it, greatly elongated, hyaline, slightly broader distally, 

 sometimes narrower in the mid-region, the terminal portion above it 

 slightly and abruptly narrower; cells III-V yellowish, granular-punc- 

 tate, cell II somewhat larger than the other two combined, cell V small, 

 triangular, hardly reaching to cell III, and usually proliferous to form 

 a small branched appendage similar to the branches of the main 

 appendage. Main appendage arising from a single small basal cell 

 seated on a well defined black insertion, its cells mostly rather short 

 and stout, more or less constricted at the septa, the basal cell bearing 

 two branches, erect, several times successively branched, the branch- 

 lets divergent often at almost a right angle; both the primary and 

 secondary appendages hyaline or pale yellowish, bearing here and there 

 a few short antheridia of the usual type. Basal cells of the perithe- 

 cium small but clearly defined above cell VI, which extends downward 

 in a point beside the end of cell II. Perithecium very large, almost 

 wholly free, paler straw-colored, with a brownish tinge below; a 

 symmetrically inflated venter clearly distinguished from a greatly 

 elongated, but slightly tapering, nearly hyaline neck-portion, above 

 which a long slender tip is abruptly distinguished, which is suffused 

 with pale reddish brown, becoming blackened distally, except the tip 

 of the outer lip-cell, which subtends the external pore. Perithecia 

 500-750 X 100-120 /x; the tip 70-75 X 18 m; the neck 50 /x at base 

 and 32 fx at distal end. Spores 45 X 7 /x. Receptacle, basal cell 

 about 160 X 70 m; the subbasal 550-780 fx by 60 /x; 70-80 /x at distal 

 end. Total length to tip of perithecium 1300-1700 fi. 



On the inferior surface of the abdomen, near the tip, of Gri/llus 

 alhifrons Sauss. Samarang, Java. 



This fine species is very conspicuous from its great size, being one 

 of the largest of all the Laboulbeniales. It bears a very remote resem- 

 blance to L. {Ccraiomyces) Dahlii, which also penetrates the host 

 by means of a well defined rhizoid which, in the present species, 

 appears to be always simple. Two infected hosts were sent me by 

 Mr. Jacobson and abundant material has been examined. In every 

 individual the cell-arrangement is exactly that of LabouUienia, except 

 that the main appendage arises from a single basal cell. This cell.
