NEW INDO-MALAYAN LABOULBENIALES. 47 



Although numerous immature specimens of this form are available 

 for examination, few mature individuals have been seen, and it is not 

 improbable that the measurements will vary considerably from those 

 given when abundant material is available. The type corresponds 

 to that of Laboulhenia in every detail, and though closely allied to L. 

 Grylli seems abundantly distinct. 



Misgomyces ornatus nov. sp. 



Relatively short and stout, pale amber-brown, the posterior margin 

 more deeply suffused. Receptacle not distinguished from the primary 

 appendage; the former consisting of four superposed cells, the basal 

 longer and narrower, distally geniculate, the rest broader than long, 

 the uppermost larger, five sided, bearing the stalk-cell of the peri- 

 thecium on one side and continuous with the primary appendage on 

 the other. Primary appendage consisting of normally three super- 

 posed cells, the basal larger and associated with a small cell which is 

 separated from it on the inner side and lies between it and the stalk- 

 cell of the perithecium to which it is firmly united ; the two upper cells 

 flattened, sub-hemispherical, bearing on the inner side branches more 

 or less copiously branched to form a usually short dense tuft; the ulti- 

 mate branchlets usually terminated by paired antheridia, which are 

 relatively long, without well distinguished necks; the distal cell of the 

 appendage also bearing at first a short outcurved evanescent append- 

 age, continvious with the deeply suffused posterior marginal wall. 

 Perithecia borne on a short, but well defined, stalk-cell; its basal cells 

 clearly developed; the lowest, which lies at the right, much larger and 

 somewhat broader than the portion of the base above it; the body 

 rather short and stout, the outer margin straight, the inner convex, 

 distally broad and abruptly distinguished from the tip, which is 

 subtended on the inner side by a conspicuous short brown blunt 

 tooth-like process; the pore minute and lateral on the inner side, a 

 subterminal outer wall-cell assuming a terminal position and extend- 

 ing upward and outward to form a blunt-tipped somewhat divergent 

 concolorous appendage, which becomes relatively long and slightly 

 sigmoid. Perithecia, including base, without terminal appendage, 

 SO-90 X 23-30 Ai; its terminal appendage 25-75 X 4.5 ^i; the stalk 

 cell 14 X 11 yu. Spores 35-40 X 2.5 m- Total length to tip of pri- 

 mary appendage 65 X 25 /j., the tuft of branches 35-45 /x. Antheridia 

 32 X 2 M.
