The British specimens referred to this name show the surface 

 of the stroma in old specimens to be greenish-black while the 

 base is of a translucent red. The American specimens are more 

 often of a yellowish color with the surface becoming greenish- 

 black. The color in the species is very variable. 



2. Chromocrea substipitata sp. nov. 



Stromata gregarious or occasionally crowded, seated on a 

 sulphur-yellow subiculum, discoid, fleshy, with the margin ele- 

 vated from the substratum, young plants substipitate ; stem short, 

 about I mm. thick and 1-2 mm. high, gradually expanding 

 upwards into the subpatellate stroma; stroma plane to a little 

 concave or convex, dull yellow, slightly punctate with the darker 

 ostiola 1-4 mm. in diameter; asci cylindrical, becoming i6-spored 

 by the separation of each original spore into two subglobose cells ; 

 spores becoming smoky-brown, 4X5 mic. in diameter.

Type locality : Nicaragua. 



Distribution : Known only from type locality. 



Specimens examined: Nicaragua, C. L. Smith (type). 



The specimen described under this name was included in the 

 Ellis collection under the name Hypocrea cubispora Ellis & Holw. 

 from which species it differs in several points the chief of which 

 is that the asci in the present species become i6-spored while 

 those in Hypocrea cubispora Ellis & Holw. are 8-spored. There 

 are other gross characters which are also sufficient to mark this 

 species as distinct from the one to which it had been referred 

 by Mr. Ellis. 



The young specimens resemble very closely Helotium citrinuin 

 (Hedw.) Fries in form but the color is not so bright.

Stromata appearing first as a speck of white tomentum, with a 

 brick-red spot appearing in the center, finally becoming fleshy, 

 rather thick and entirely brick-red without, and white within,
