Teratomyces Philonthi nov. sp. 



Perithecia commonly two, long and slender, a basal middle and distal 

 portion distinguished, corresponding to the basal, middle and the distal 

 wall- and lip-cells, the basal portion slightly inflated, purplish, the middle 

 distinguished from it by a slight elevation at the septa ; the middle nearly 

 hyaline, rather abruptly narrowed, its margin slightly concave owing to 

 a slight distal enlargement, which, in mature specimens, distinguishes it 

 rather abruptly from the much shorter narrower subconical mostly sym- 

 metrically truncate colorless distal portion; the stalk-cell. rather short, 

 concealed by the appendages ; the basal cells forming a squarish base. 

 Receptacle relatively small, symmetrical or asymmetrical, the basal cell 

 translucent brownish, the subbasal cell very small, flatfish, wholly in- 

 volved by the deep nearly opaque suffusion of the lower half or more of 

 the upper cell, which is nearly hyaline above. Appendages short, 

 slightly exceeding the base of the perithecium, rather rigid, sliglitly 

 divergent, for the most part dark brown ; forming a rather dense tuft, 

 many ending in pointed cells, the slender terminations straight or bent 

 and forming the beak-like cells characteristic of tlie genus. Spores 

 36 X 4/x. Perithecia 140-175 X 25-30 ^u, the stalk-cell about 35 /x. 

 Eeceptacle about 85 X 35 /x. Appendages (longest) about 70 /*. Total 

 length to tip of perithecium 250-300 /x. 



On Philonthus sp. indet., British Museum, No. 365, Hungary. 



Corethromyces Brazilianus nov. sp, 



Perithecium and receptacle much as in C. Cryptobii, but differing dis- 

 tinctly in the character of its appendage, the inner main branch of which 

 consists of from four to six cells, the others very short, all nearly opaque, 

 the branchlets long rigid divergent, curved abruptly outward at the tips. 

 Total length to tip of perithecium 200-375 /a. Spores 28 X 3 yu,. Peri- 

 thecia 90-175 X 28-38 /M. Appendages to tip of branchlets 140-200 /x. 

 Two specimens from Colombia, apparently identical, are much larger; 

 total length 610 yu, ; branches of appendages 540 /x ; perithecia 450 fx.
