522 Eumycetes. 



basal cell and foot of the female, consisting of several superposed 

 cells and bearing terminally and laterally from one to several large 

 flask shaped simple antheridia, female consisting of a Single basal 

 cell from which ihe stalk-cell of the perithecium arises distally; 

 ascogenic cell Single, spores 1-septate. A. Platensis, on Tomoderus 

 forticornis Pic. A. nigripes, on the same. 



Cryptandrornyces nov. gen. with C. genicidatus, on Connophron 

 nov. sp., receptacle consisting of two superposed cells, the upper 

 bearing a solitary stalked perithecium, and an appendage formed 

 by a simple series of superposed cells without branches; several 

 consecutive cells of this series at first functioning as antheridial 

 cells, from which sperm cells appear to be discharged directly through 

 perforations of the wall on the inner side. Perithecia normal. 



Synanäromyces nov. gen., nearly related to Aconipsomyces. S. 

 TeJephani, on TelepJiamis sp. S. genicidatus, on the same host. 



Stigniatoniyces Anoplischii, on Anoplischiiis sp., most nearly 

 related to 5. viresce}is. The arrangement of the distal antheridia 

 recalls that seen in Helminthophana. 



Zeugandromyces nov. gen. with Z. anstralis on Scopaeus laevis 

 Sharp. 



Corethromyces. Both Rhadinornyces and Sphaleromyces cannot be 

 maintained as distinct genera but should be merged in Corethro- 

 myces. A new description of the genus, in which Stichomyces Stili- 

 colus also is included, is given. It is very diflicult to determine the 

 exact nature and association of the antherida in many forms inclu- 

 ded in the genus, therefore it may be assumed that all those in 

 which a two-celled receptacle bears distally a Single perithecium 

 on the one band and a Single main appendage on the other, bearing 

 branches on its inner face and terminally, should be sought under 

 Corethromyces, when it possesses no characters which would exclude 

 it from the genus. C Argentinus, on Cryptohium sp., distinguished 

 by its very large and long perithecia, and the stout, erect and 

 elongate simple branchlets of the appendage, certain short oblique 

 branchlets below their origin being alone deeply suffused. C. Ophitis, 

 on Ophites Fauvelii, distinguished from C. purpiirascens by the 

 characters of the appendage. C. Platensis and var. gracilis, on La- 

 throbium nitidiim Er. C. Scopaei, on Scopaeus fraier Lynch, peculiar 

 from the fact that no foot is distinguished from the peculiar rocker- 

 like basal cell of the receptacle, which is usually quile hyaline. C. 

 hninneohis, on Stiliciis sp. C. pygniaeus, on Stiliciis sp., allied to C. 

 Stilici, from which it differs in the form' of the perithecium and 

 receptacle, as well as in the character of the outgrowth from the 

 latter. C. sigmoideus, on Stilicus elegans Lynch, closely allied to C. 

 pygniaeus, but distinguished by its sigmoid habit, and the different 

 slructure of its appendage and perithecium. C. uncigerus , on Stilicus 

 elegans, easily distinguished by the peculiar tip of its perithecium. 

 C. armatus, on Stilicus sp., distinguished by its appendiculate peri- 

 thecium, and the peculiar position of its appendage. C. rhinoceralis, 

 on Finophilus sujfusus Er., closely allied to C. indicus, from which 

 it differs chiefl3^ in the clavate form of the perithecium, and in the 

 highly developed spine which Springs from a projection of one of the 

 subterminal wall-cells. C. macropiis, on Heterothops nov. sp., most 

 clearlj'- distinguished hy the peculiar conformation of the tip of the 

 perithecium and its relatively large receptacle and foot. C. rostratus, 

 on Heterothops sp, 



Stichomyces Catalinae, on Conosma testaceum Lat., the character
