Haplosporidium, the question being whether

genus / HAPLOSPORIDA

Description

there are extensions from the posterior end of the spore . I agree with Sprague (1963) that H. scolopli does not have such extensions as shown i n Caullery and Mesnil's 1905a paper in Fig . 1 and PI XI, Figs. 17a,b and their 1905b paper in Fig . 2. Ormieres ( 1980) disagrees, stating that the drawing in Fig . 17c of Caullery and Mesnil (1905a) contains a spore with extensions. Two delicate lines were drawn, trailing from the posterior end of the spore, but I believe that they probably represent membranes from remnants of the epispore cytoplasm and not extensions supported by internal filaments as in other species (see below) . This interpretation is supported by the Caullery and Mesnil 's ( 1 9 0 5 a) statement: "II y a en outre une membrane externe beaucoup plus delicate et qui n'est souvent reconnaissable qu'a quelques debris (fig. 17b et c)" . Thus , I accept the type species, H. scolopli, as being a species without prominent extensions. With the acceptance of the genus Minchinia and the assumption that the original description of H. scolopli did not include extensions visible in the light microscope , I have proposed the above key to the genera Hap/osporidium and Minchinia . Thus the following species needs to be transferred from
