The erect hyphae are septate and after arising- a short dis- 
tance above the substratum each cell sends out a short branch 
near the outer end. These short branches become the spor- 
ophores, and at first are indistinguishable from the main 
hypha except in size. Almost immediately the tips of the 
sporophores bend upward at approximately right angles and 
the portion beyond the bend rapidly becomes closely septate, 
having six to nine septae. The sporophores very soon become 
boat-shaped with the keel toward the main hypha. Upon 
the side away from the main hypha there arise small protu- 
berances, the first appearing nearest the bend, and then being 
produced in succession toward the tip. 
These growths early begin to show a slight swelling, form- 
ing a kind of head at the tip, which later lengthens into the 
fusiform spores; these are constricted into a very fine thread 
at the base, which connects them with a swollen base (basi- 
dia) that joins them to the naviculate sporophore. 
Saccardo places this fungus in that group of the Hypho- 
mycetes called the Mucedineae, because of the looseness and 
lightness of color of the mycelium. Also among the Amer- 
osporeae of the latter, because of the shape and color of the 
spores. 
In quoting the original description in his Sylloge Fungorum 
Saccardo says that the sterile hyphae are procumbent, with 
the fertile erect, with both branched and septate; the spores 
are borne on short lateral branches and in two rows along the 
face of the naviculate sporophore, being cylindric-fusiform in 
shape, and measuring 10-20x3 /u.; that it is parasitic on Muco 
and the Saprolegneae. After giving the habitat a note is 
added saying that Cremans describes some of the spores as 
being borne in chains, and Kngler & Prantl reproduce fig- 
ures of the fungus which show some of the sporophores 
bearing catenulate spores, which are nearly globose in shape. 
After the note Saccardo makes the very significant remark 
that the appearance of the catenulate spores is exceedingly 
strange.
