1S4 THE PHYCOMYCETES 



contains many facts regarding the development of these fungi, 

 but further investigation of them is required.

ECCRINALES 



The position of this order among the Phycomycetes is not 

 estabhshed. In fact, its members are not included in Saccardo's 

 Sylloge Vimgonnn, even though some of them were first de- 

 scribed nearly 100 years ago. Leidy (1849, 1849a, 1849b) first 

 observed a capillary, unbranched organism attached by means of 

 disk-like holdfasts to the intestinal wall near the anal opening of 

 Spirobohis viarg'matiis. To this organism he gave the name 

 Enterobnis elegans, placing it among the Confervaceae. He then 

 added t\vo other species, E. spiralis in Ii/his piisilhis, and E. at- 

 teniiatus in Fassahis cormitus. In the following year Leidy (1850) 

 created the additional closely related genus Eccrina and changed 

 the name Enterobrus to Enterobryus. Three years later Robin 

 [Leger and Duboscq (1929)] described another species and in- 

 dicated that Enterobryus was among the Saprolegniales. 



Little attention was sriven these org^anisms until 1905, when 

 Leger and Duboscq began a series of studies of them. Among 

 recent reports through which the ^\•orker may become acquainted 

 with the Eccrinids are those by Poisson (1929) and Leger and 

 Duboscq (1916, 1929, 1933). Leger and Duboscq (1929) classi- 

 fied them into two orders, Eccrinales and Amoebidiales. The 

 Eccrinales have longr filaments and are attached to the intestinal 

 wall of terrestrial, marine, and fresh A\-ater Arthropods. They 

 reproduce by endogenously formed microconidia and macro- 

 conidia. The Amoebidiales have short filaments or are saccate, 

 are attached to the external cuticle or rectal chitin of Crustacea 

 and insects, and form only one type of endospore. Approxi- 

 mately 10 genera have been described, but it is probable that the
