from lack of evidence which would refer it elsewhere. In its 

 mode of growth it recalls Mortierella and similar forms: but 

 its type of spore formation, as well as the character of its 

 spores, is quite distinct from that which occurs in any of the 

 genera of Mucoraceae; among which, however, it is not im- 

 possible that it may eventually find a place.

Gonatorrhodiella nov. gen. — Sterile hyphre hyaline, creep- 

 ing, septate and branched. Fertile byphse erect, sparingly 

 septate, swelling into a spherical terminal sporiferous head, 

 which after maturity may become once or twice proliferous, 

 the proliferations also forming similar proliferating heads, the 

 resulting hypha presenting ultimately the appearance of a 

 successively inflated filament. Spores formed directly from 

 short processes covering the fertile head, in chains of a defi- 

 nite number, by successive apical budding. 



Gonatorrhodiella parasitica n. sp. — Plate XIX, figs. 7-10. 



Fertile hyphcX gregarious, simple or rarely dichotomously 

 branched, sparingly septate, hyaline becoming pale fawn 

 colored, seldom more than five times successively proliferous, 

 8-1 2// in diameter, sometimes more than 1 mm. in height. 

 Sporiferous head nearly spherical to oval, rarely producing 

 more than a single proliferation, 25-35// in diameter, maxi- 

 mum 43 x 36/x Spores in chains of three, hyaline, then fawn 

 colored, oval to elliptical, caducous, 8.5x6—12x7// the basal 

 ones the largest. 



On Hypocrea and Hypomyces. Connecticut. 



This species has been met with in several localities about 

 New Haven always growing directly upon, or running a short 

 distance from certain species of Hypocrea and Hypomyces on 

 which it appears to be parasitic. The genus is distinguished 

 from Gonatorrhodum Corda, to which it bears a superficial re- 

 semblance, by the absence of the large, septate, subverticillate 

 "ramuli" which give rise to the spores in the last named 

 genus; as well as by its definite spore formation, the indefinite 

 and often branched spore-chains of Gonatorrhodum being re- 

 placed by short simple chains composed of a small and in- 

 variable number of spores. Whether the successive apical 

 formation of the spores in the present genus does not consti- 

 tute another essential difference, cannot be determined from 

 Corda s description; but from his figure as well as from 

 analogy with other genera, like Aspergillus, Verticillium, etc 

 to which he compares it, a successive basal spore formation
