No type specimen of this species has been seen, but a specimen 

 collected on decaying leaves of Musa in Jamaica by Dr. W. A. 

 Murrill corresponds well with the above description. The speci- 

 mens examined differ from Nectria Peziza (Tode) Fries, which 

 they quite closely resemble in general appearance, in the nature 

 of the fairly well developed hairs which clothe the perithecia, and 

 also in the spores, which are longer and proportionately narrower 

 than in that species. Also, the perithecia are of a deeper red 

 color.

Perithecia free, often closely gregarious, or scattered, with no 

 true stroma but perithecia often surrounded with radiating white 

 mycelia which give to some of the species a stromate appear- 

 ance ; perithecia globose to ovate, red or yellow ; asci elongated, 

 8-spored; spores elongated, more than 1 -septate. 



Type species : Calonectria Daldiniana de Not. 



Distinguished from Nectria by the many-septate spores. The 

 genus as treated here is used in its restricted sense including only 

 the non-stromatic species. The three species described here occur 

 on the remains of other fungi so that the substratum with the 

 white mycelium which surrounds each perithecium gives the 

 stromatic appearance but close examination will show the peri- 

 thecia to be entirely free, not connected by a stroma or stromatic 

 base. 



Spores small, not exceeding 15 mic. in length. 1. C. erubescens. 



Spores large, 25-35 mic. in length. 



Spores subelliptical ; plants occurring on fungi on dead 



branches. 2. C. diminuta. 



Spores fusiform ; plants on leaves. 3. C. melioliodes.

Perithecia minute, gregarious in clusters or scattered, sur- 

 rounded by a scant growth of radiating mycelial threads, at first 

 pale red, fading to pale yellow, subglobose, with a minute ostio- 

 lum, often collapsing when dry, becoming pezizoid ; asci clavate,
