Lake Maxinkuckee, Physical and Biological Survey 155 



cloudy masses in the bottom in shallow water. In 1906 (July 24) 

 considerable was seen in Lost Lake attached to plants, by being 

 tangled up with them. 



60. VAUCHERIA sp. 



Abundant, forming thick, dark green, felted masses in the bot- 

 tom of shallow ditches near the lake, and more especially on the 

 surface of saturated ground near Overmyer's spring. Not found 

 in fruit. There may have been several species. Not found in the 

 lake itself. 



61. CLADOPHORA FLOTOWIANA 



Collected in the Inlet, July 30, 1906. Fruiting cells large and 

 clavate. 



62. CLADOPHORA GLOMERATA (Linnseus) 



Abundant in the lake, forming dense tufts growing attached 

 at the base to submersed stones along the shore; most abundant 

 along Long Point and off from the Depot pier. The dense tufts 

 furnish hiding places for numerous small larvse, snails, beach fleas, 

 caddis-cases, etc. Filaments are frequently thickly beset with the 

 parasitic diatom Cocconeis pediculus. 



63. PRASIOLA PARIETINA (Vaiicher) 



Found in a single shore collection of miscellaneous material, 

 such as Utricularia, Conferva, Chaetophora, etc. 



64. MICROTHAMNION sp. 



A dichotomously branching slender alga, found abundantly in 

 shallow water around the margin of Lost Lake in the spring of 

 1901, the basal portion being attached in the mud. It closely re- 

 sembles West's figure of M. strictissimiim Raben. 



65. DRAPARNALDIA GLOMERATA (Vauchcr) 



Not found in the lake in great quantities but growing thickly 

 on submerged dead leaves in the bottom of woodland ponds in the 

 spring. Obtained from a pond near Farrar's, April 24 and 27, 

 1901. A considerable quantity was seen along a ditch west of the 

 lake. It thrives best in cold water and for that reason is generally 

 seen only early in spring. A little was collected in the lake May 

 25, 1901. 



66. MYXONEMA RADIANS (Kuetzing) 



Found in Norris Inlet, July 30, 1906, attached to Cladophora. 



(As has been pointed out by Hazen, the familiar name Stigeo- 

 clonium Kuetzing F-hould be replaced by the older name Myxonema 

 Fries.)
