DESCRIPTIONS OF FUNGI 
For the identifications the systematic works of ENGLER and 
PRANTL (36), RaBENHORST (37), and SAccarDo (38) were used. 
The work of OupeMANs and Koninc (29) was also found very use- 
ful, and the work of LitcER (40) was referred to. 
Mucor amsicuvs Vuill—Mycelium floccose, spreading rapidly, 
soon covering the substratum and sending aerial hyphae 1-3 cm. 
above; becomes dusty gray by formation of sporangia. Hyphae 
branched, hyaline, 6-10 MB in diameter. Sporangiophores very 
variable in length; branching racemose-sympodial, richly mixed. 
Each method occurs separately and the two are often combined 
in the same fructification. In the racemose type the terminal 
sporangia are often larger than the lateral, the whole appearing 
clustered. In the sympodial branching a cross wall cuts off a 
sporangiophore, and then a lateral branch forms basal to this wall. 
The lateral branch continues growth, repeating the process, thus 
developing a sympodial system. The two types of branching 
are often combined by one or more branches of a racemose cluster 
becoming elongated and developing in the sympodial way. 
Branches of the sympodium 10-100 w long. Sporangia globular, 
toom in diameter, larger terminal sporangia 125, dusty 
brown incolor. Columella present, conical to globular, 35-5040 
60 » in diameter, slowly deliquescent leaving a slight collar. Spores 
elliptical, seldom globular, 3~5 5-7 u in diameter, smooth.—Fig. 2. 
This fungus showed extreme variation in the branching of its sporangio- 
Phores. While its diagnosis, so far as branching is concerned, comes very neat 
i 7. . slobosus Rabenh., its Spores are typically elliptical and not globular. 
© same time, the columellas are conical to globular and not pyriform.
