Nearly hyaline. Keceptacle rather slender, the basal cell several times as long as the squarish sub- 
basal cell; the cell above the latter nearly equalling it in size and separated by an oblique septum from 
the lowest of the marginal cells, which are all subequal; the terminal appendiculate cell of the usual 
form, relatively large and long, without any distinct basal enlargement; the tip of the lower appendicu- 
late cell curved slightly outward. Perithecium relatively very large, long, slender, usually curved side- 
wise throughout, the upper half tapering very slightly to the curiously modified, clear black contrasting 
tip, which resembles the parity open beak of a parrot; a larger upper recurved mandible-like process 
being separated from a second, that resembles a lower mandible, by a hyaline area which includes, and 
extends back from, the pore; the lower lip-cells translucent, but suffused with brown in such a way as 
like process projecting slightly between the "mandibles." Spores very numerous, 
completely filling the cavity of the perithecium, greatly attenuated, 85 X 2.5 ft. Perithecium 200 X 30 //. 
Ri eptade to tip of distal cell 140 fL Total length to tip of perithecium 290-300 //. 
On the posterior legs of Laccophilus prozimus Say. Lake Eustis, and Daytona, Florida. 
This is one of the larger species of the genus and is clearly distinguished by its tip which resembles 
a parrot's beak and by its large size and slender habit, Two hosts were found bearing the individuals, 
in groups in the position indicated, which were conspicuous from their large size and contrasting color.

Foot relatively small. Basal cell of the receptacle small and narrow, its basal half or more suffused 
with dirty blackish-brown, above hyaline; subbasal cell longer than the basal, and of nearly the same 
diameter throughout; the three cells above it subtriangular, about equal in size, darker straw-colored, 
or pale amber-brown: the lower marginal cell of the distal portion of the receptacle narrow, clean cut, 
darl r amber-colored; the lower appendiculate cell above it hyaline, small; the two remaining cells 
above and external to it, forming an opaque appendage, shaped like a knife-blade, its tip rounded out- 
ward from the inner side to an external blunt apiculus. Perithecium suffused below with pale amber- 
brown, long and slender, narrower opposite the insertion of the lower appendage, expanding slightly 
above It. tic am a WoIIt™, «t^. ~J : i i ,. , , .. . ll B ' r & & J
