CHITONOMYCES AND RICKIA. 5 



C. denfifcrus Th. A form closely reseml)ling this species, and in 

 which the base, only, of the tooth-like perithecial appendage is devel- 

 oped, was found on several specimens of Laccophihis, No. 2680, from 

 Sangre Grande. The slender termination of the perithecium is usually 

 rather irregularly bent outward and then inward at the apex, the 

 whole distal portion sometimes erect, and sometimes bent partly 

 across the distal cells of the receptacle. On the right side of cell g, 

 are two superposed dark tubercular patches which occupy most of 

 the surface on this side. These patches are not always very conspicu- 

 ous, but are present in the type of deniiferus, although they were 

 overlooked in the original description and figures. 



C. Hydropori Th. X form not distinguishable from the types of 

 this species was found on a species of Hydroporusf from Manila, P. I. 



Chitonomyces cerviculatus nov. sp. 



Rather short, subsigmoid when viewed sidewise, uniformly tinged 

 with dirty yellowish brown, with certain deeper amber-brown suffu- 

 sions. Foot large; basal cell short and stout, somewhat longer than 

 broad; cell b about twice as broad as long, horizontal, more strongly 

 convex on one side; cells c, d and e small and subequal, subtriangular, 

 dissimilar; cell d somewhat larger; cell/ tapering to a very narrow 

 base, lying almost wholly above cell e, and becoming much broader 

 distally; where it is slightly and symmetrically intruded between the 

 small narrowly triangular cell h, and cell i, which is distorted by an 

 umbonate prominence, on the right side, that throws the insertion of 

 cell i asymmetrically to the left, so that it may be sublateral in posi- 

 tion; cell i symmetrical, broadly subhemispherical, the insertion of 

 the primary appendage terminal. A short stout spiral appendage is 

 present, arising on the right side, within and near the apex of cell h. 

 Perithecium relatively large, irregularly subsigmoid; the outer margin 

 of the venter concave, amber-brown, its distal end bulging abruptly 

 on the left side below the stout, neck-like, strongly incurved terminal 

 portion; which is of nearly uniform width to the apex, slightly broader 

 below; the subterminal wall-cell, on the outer side, forming an amber- 

 brown, somewhat appressed and distally outcurved appendage; 

 which is sometimes subsymmetrical with the thick, dark amber 

 margin of the opposite side; the apex broad, somewhat asymmetri- 

 cally rounded, bent inward; the hyaline lips slightly prominent. 

 Spores about 36 X 2.5 fi. Perithecia, body 45-50 X 18 ai> the neck
