Pilze. 185 



-Culturen auf Most beherbergen die Perithecien, deren in grosser Zahl aus- 

 gestreute röthliche Sporen die intensivere Fäi'bung veranlassen. 



In den Perithecien hat der Pilz einige Aehnlichkeit mit E u r o t i u m , 

 während die Conidienträger wieder mehr sich denen von Monascuj 

 ruber nähern. Jedenfalls bleibt die Verwandtschaft noch aufzuklären. 

 Costantin gibt ihm den Namen Eurotiopsis Gayoni.

Die Diagnosen der neuen Gattungen sind folgende : 



Sphaleromyces n. g. Keceptacle cousisting of two superposed cells, the 

 distal beai^ng the appendage laterally, and the stalk eell of the perithecium 

 terminally. Perithecium asymmetrical, the apex somewhat poiuted ; separated 

 froiu its short stalk cell by three basal cells. Appeudage clearly distinguished 

 froin the receptacle, composed of a basal cell bearing a series of buperposed 

 cells, each giving rise from its iuner upper angle to a single sliort septale 

 brauch wich may bear flask-shaped antheridia. Hpores oiiee septate involved 

 in mucus. Asci arising in a double row from a siugle large ascogenic cell. 



Comjjsumyces n. g. Receptacle consisting two superposed cells, the distal 

 bearing from its extremity a Cluster of appendages and one or more stalked 

 peritlieeia. Appendages sterile or fertile, simple or branched, septate, the fertile 

 ones bearing oue or more siugle oue-celled antheridia separated by oblique 

 partitions from the extremities of successivecells composing the main axis of 

 the appendage. Perithecia symmetrical, conical, borne on two superposed stalk 

 cebs an three small basals cells, the basal stalk cell producing from its distal 

 eud a simple sterile appendage. Asci 8-spored. Spores once septate. 



Moschomyces n. g. Receptacle composed of a suckerdike compaeted mass 

 of parenchymatous cells penetrating the softer chitiu of the host and giving rise 

 above to numerous free cells from the distal ends of which are produced soli- 

 tary stalked perithecia and appendages. Perithecium very large, subconical, 

 pointed, the apex symmetrical, borne on two simple superposed stalk cells, 

 followed by three small basal cells; the basal stalk cell, bearing one-celled an- 

 theridia laterally. Asci subcylindrical, eigbt spored, arising in great numbers 

 and in many rows from a single ascogenic cell or centre. Spores minute, aci- 

 cular, one septate. 



Camptomyces u. g. Receptacle consisting of two superposed cells, the 

 Upper bearing the short-stalked perithecium laterally and the antheridial apen- 

 dage terminally. Perithecium narrow , with coarse-lipped asymmetrical apex. 

 Appendage consisting of a single large basal cell bearing the antheridium ter- 

 minally. Antheridium multicellular, subconical, with a prominent terminal pore 

 for the discharge of the numerous roundish antherozoids. Trichogyne developed 

 as a small vesicular prominense above a permanent ear-like appendage which 

 ariser laterally from the young perithecium. Ascogenic cells two in number.
