ZODIOMYCES nov. gen. 



Main body of the fundus tapering to a narrow base of attachment, 

 parencbymatously nmltictllular ; the distal end cup-shaped, with a 

 more or less well marked rim, within which arise directly from 'the 

 central parenchyma numerous stalked perithecia and simple, septate 

 sterile filaments. Peritliecia asymmetrical; the apex bent to one side; 

 appendaged ; borne on simple, septate pedicels, having a rounded 

 prominence just below the perithecium. Spores hyaline, fusiform, 

 asymmetrically once-septate, involved iu mucus. 



ZODIOMYCES VORTICELLAKIA noV. sp. 



Livid with a central yellowish tinge, the base more or less suffused 

 with dull purple above the almost black point of attachment. Peri- 

 thecia numerous : at first terminal, then lateral by the subsequent out- 

 growth of the terminal cell of the simple, cylindrical, several-septate 

 pedicels which bear them : strongly bent away from a pair of ear-like 

 appendages placed close together near the summit which curve away 

 from the almost symmetrical rounded apex of the perithecium. Two 

 additional appendages, longer, more slender, slightly curved and taper- 

 ing, arise from slight prominences on opposite sides of the peri- 

 thecium, at a point about two thirds of the distance from the base to 

 the apex. Sterile filaments ai'ising among the perithecia ; simple or 

 ra-ely branched, cylindrical, septate, tapering sliglitly towards a 

 rounded apex and extending some distance beyond the perithecia. 

 Main body, or receptacle, trumpet-shaped ; made up of very numerous 

 small, squarish or slightly elongate cells, smaller towards the distal end 

 and disposed in more or less regular transverse layers ; the base of 

 attachment composed of several small cells placed side by side and 

 more or less deeply tinged with purple. The basal portion may or 

 may not grow out laterally, on one or both sides, forming rounded 

 processes of parenchymatous cells of variable size, which may be in 

 contact with, though not attached to, the host. Spores slender, fusi- 

 form, hyaline, slightly granular, involved in mucus, asymmetrically 

 once-septate, 45 x 2.5-3 //. Perithecia 55 X 15-18 /x ; ear-like appen- 

 dages 15-30 X 5 yti ; lateral appendages, maximum 50 X 3 /x ; pedicels 

 35-50 X 3.5-4 ju. Sterile filaments (longer) 200 X 3-4 /a. Main 

 body exclusive of perithecia and sterile filaments, largest observed 

 400 X 185 II at distal end ; smaller specimens 225 X 100 /x.
