halla , jeju island , 13 july , 1997 , l - y-1445 - 1 , 1445 - 2 and 1445 - 3 this species is very similar to e. rossii , from which it is distinguished by the larger thalli and primary axis composed of some more cells than the latter .
thalli were collected from elytra , metasternum , abdomen and legs of host insects living on russula densifolia ( russulaceae , agaricales ) in the deciduous broad - leaved trees forest .

the present species is closely related to e. cioideus , but it differs from following features ; in e. cybocephali the primary axis are composed of 5~9 superposed cells and not branched , whereas in e. cioideus they are composed of 8~10 superposed cells and one or two appendages are branched at the distal portion .
thaxter 's materials ( 1931 ) showed two kinds of specimens having the primary ( thaxter , 1931 , fig .
korean materials are nearly agreed with his representatives , although the length of primary axis are longer than those of thaxter .
they are identified to e. cybocephali , because of the structures of cells and the figures of thalli are closely related to the latter .
host insects were caught in a mountain forest with quercus mongolica ( fagaceae ) on suilus grevillei ( polyporaceae ) .
this species have been found only on the genus cybocephalus as far , but korean materials have been collected newly from the genus pseudocolenis .
the axis of the receptacle and primary appendages consist of 9~13 superposed cells that are slightly elongated or ( except for the basal cell ) flattened ; the receptacle gradually broadens to the third cell ; the higher situated cells are narrower and of nearly the same breadth
. the fourth cell of the receptacle divides , laterally separating on one or both side the stalk cell of the perithecium and on the other the basal cell of the secondary appendage ; antheridia directed upwards , arranged in one row , are separated in the upper corner of 3~5 distal cells of the receptacle .
a few long branchalets ( up to 56 m long ) arise from the distal cell of the receptacle .
the secondary appendage resembles the paralled distal part of the receptacle , but is usually made up of somewhat more narrow cells .
the stalk cell of the perithecium slightly elongated , basal cells obvious . the perithecia almost cylindrical elongate , 1~3 in number , 53~68  14~23 m ; the apex narrows fairly abruptly to a narrow rounded top ; one side of the subapex with a projecting part .
