THAXTER. — NEW LABOULBENIACEyE. 171 



toward the pore contrasting with the nearly colorless lip-edges below it. 

 Receptacle pale brown or dirty olivaceous, elongate, normal. The in- 

 sertion-cell nearly horizontal external to cell V, unmodified. The outer 

 basal cell of the appendages giving rise to a single subcorneal brown 

 prominence bearing branches terminally and externally and protruding 

 beyond the inner basal cell, which is indistinguishable from the very 

 numerous branches arising from it in all directions ; all the branches 

 hyaline, their basal cells bearing distally several branchlets which may 

 again be branched, the four to eight lower septa dark. Perithecia, 

 average 175x44/x; the spine-like apex 10-12 p. Total length to tip 

 of perithecium 400-575 p • to insertion-cell 275-400 p ; greatest width 

 55-70 fi. Appendages about 70 p. 



On Dineutes ?, Brit. Mus. No. 482, Adelaide River, Australia. 



Laboulbenia Dineutis nov. sp. 



Perithecium free except at the base, dark brown, the inner margin 

 straight, the outer curved from the base to the tip, which is not well 

 differentiated, the lip-cells inconspicuously modified to form an inner 

 tooth-like brown prominence curved inward, and a median small brown 

 rounded elevation, which is covered by an outer hyaline externally 

 brown broad irregular elevation. Receptacle elongate or rather short, 

 dark brown inconspicuously punctate. Appendages much as in L. hete- 

 rocheila, the branchlets closely septate with dark septa near the base 

 and (in unbroken specimens) with long hyaline aseptate or remotely 

 septate terminations three to four times as long as the basal part. 

 Measurements very variable. Perithecium, (Ceylon) 275X72/1, 

 (India) 140 X 40 p. Total length to tip of perithecium, (Ceylon) 1 mm., 

 (India) 400 p, (Madagascar) 350 p. Appendages, (Ceylon) 200 p. 

 Spores, (Ceylon) 75 xC/i.
