Dichomyces Madagascarensis dot. Bp. 



Basal cell deeply suffused with brown. Lower tier very long and 

 Blender, opaque except for a faint median translucent Line : middle tier 

 with three to live of the median cells distinguishable, red-brown ; the n si 

 indistinguishable in the opaque margins which extend upward to form 

 long fork-like outgrowths on either side that may reach nearly to the tips 

 of the perithecia; antheridia not large, brownish: upper tier consisting 

 of about twenty-one to twenty-three cells, tinged with reddish brown, 

 relatively large, deeply concave distally ; the median cells like those of 

 the middle tier, marked by fine faint transverse stria;, bearing normally 

 two perithecia which are loug and Blender, often Blightly curved and 

 divergent, pale reddish brown, the tip narrow, the posterior lip-cells form- 

 ing two small, slightly divergent projections (like those of D. furcif* 

 but relatively smaller) curved at the tips, the anterior lips meeting ;,, a 

 point between them. Appendages hyaline, sometimes equalling the peri- 

 thecia in length. Spores very Blender and abundant, 35 < "_'<<. Peri- 

 thecia 125-135 < 25/i. Total length to tip of perithecium i 0/x- 

 Receptacle 225-240 x 105 /a.

Dichoniyces vulgatus nov. Bp. 



Receptacle short and stout, the basal cell small squarish hyaline; the 



lower tier externally opaque, except the who! ■ the middle of the median 



cell or only its ppper end, the opaque margin divergent extending above 

 the base of the second tier, the blackened margin of which is continuous 

 with that of the first tier; sometimes, like it, divergent, more often 

 abruptly less divergent or evei erect, extending upward to form on either 

 side free fork-like, usually opaque, sometimes hyaline projections as in />. 

 •US which may extend to a point somewhat above the base of the 



perithecia or may be almosl obsolete; the three middle cells of the middle 



tier usually more or less conspicuously punctate below, with transversely 

 elongated blackish brown spots: the antheridia normally placed, unusu- 

 ally long and large, pointed, with two or three short, inconspicuous normal 

 appendages placed one behind, the rest external to it. The upper tier 

 distally concave, consisting of from fifteen to twenty-one cells, producing 

 normally four perithecia associated as usual with short stout typical 



append Perithecia usually i traight, rather stout, pale reddish
