given in all respects except for the absence of a single supra-basal 

 cell, the receptacle in the present species becoming multicellular above 

 the basal cell. Further material of Cantharomyces, although diligently 

 sought for on Staphylinidae, has not been obtained. The new genus 

 Hesperomyces seems to present such important differences from its 

 ally, Stigmatomyces, as to render necessary the separation of the two. 

 The lateral development of its asci, as well as the lower insertion of 

 its antheridial appendage, suggest its relationship to Helminthophana, as 

 does its very large, thrice-constricted perithecium. 



The additions to the genus Lahoulbenia, which do not include sev- 

 eral species descriptions of which are reserved until further material 

 can be obtained, are, as usual, the most numerous, and conform 

 strictly to its more simple type. The highly developed branching 

 trichogyne, previously mentioned in connection with L. elongata, is pres- 

 ent in a number of the species described, and in the younger stages at 

 least the bottle-shaped autheridia, to which attention was called in my 

 previous paper, are invariably present. From the latter the emission, 

 singly, of spermatia has been repeatedly observed. The definite isola- 

 tion of asci containing immature spores, an observation readily verified 

 in L. NehricB, should also be mentioned as setting the ascomycetous 

 nature of the group beyond further question. Other points of mor- 

 phological interest have been noticed in connection with certain 

 abnormal forms, in which the perithecium may be partly or wholly 

 replaced by antheridial appendages, with or without the usual black 

 base of insertion ; while in a few cases, where fertilization had appar- 

 ently not taken place, the initial cells which usually give rise to asci 

 were observed to produce numerous long filaments growing out 

 through the pore of the perithecium and filled with spermatia-like 

 bodies. 



As in the previous note, the term receptacle is used to designate the 

 main body of the fungus, the side bearing the perithecium being spoken 

 of as the inner, while that bearing the pseudoparaphyses is spoken of 

 as the outer, where this distinction is possible. As a matter of con- 

 venience, the eight typical cells of the receptacle in Lahoulbenia are 

 numbered as follows : the basal (1) ; the supra-basal (2) ; the cell above 

 2 on the outer side (3) ; the cell above this (4) ; the cell formed by a 

 partition across the upper inner angle of 4 is numbered (5) ; the cell 

 above 2 on the inner side is numbered (6) ; while of the two remaining 

 small cells which form the base of the perithecium the inner is num- 

 bered (7), the outer (8).
