Teratomyces Philonthi nov. >p. 



Perithecia commonly two. long and Blender, a basal middle and distal 

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

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

 distinguished from it by a Blighl elevation at thesepta; the middle nearly 

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

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

 rather abruptly from the much shorter narrower Bubconical moBth sym- 

 metrically truncate eolorless distal portion; the Btalk-cell rather short, 

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

 Receptacle relatively sin dl. symmetrical or asymmetrical, the basal cell 

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

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

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

 Blightly exceeding (he base of the perithecium, rather rigid, slightly 

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

 many ending in pointed cells, the slender terminal ions straight or bent 

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

 oG x \ fj.. Perithecia 1 tO-175 X 25-30 **, the stalk-cell about :)'>,,. 

 Receptacle about 85 X 35 ll. Appendages (longest) about 7<J/x. Total 

 length to tip of perithecium 250-300 fx. 



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



Corethromyces Brazilianus nov. sp 



Perithecium and receptacle much as in ('. 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 200-37.J ll. Spores l'S X 3 ll. Peri- 

 thecia 90-175 x 28-38/*. Appendages to tip of branchlets i 10-200 /*. 

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

 total length 610 /i ; branches of appendages 540 /* ; perithecia 150 /i.
