Fungous Flora of the Soil 445 



Heterothallic ; zygospores globose, very variable in size, mostly about 

 looM in diameter, opaque, black; exospore with large, plate-like, opaque 

 thickenings; suspensors formed from the stolons, with a circle of 10-18 

 one-celled, green appendages that interweave with those of the opposite 

 side and more or less surround the zygospore.

 Alucor corymbifer Cohn. Lichtheim, Zeitsch. IQin. Med. 7: 174. 1884. 



Sporangiophores creeping, forming a white fioccose felt, terminated by 

 a corymb of branches that are more or less elongated and carry sporangia ; 

 shortly beneath this corymb, the branches are disposed in groups. These 

 branches carry much smaller sporangia. Sporangia erect, hyaline, 

 pyriform, with an infundibuliform apophysis that gradually passes into 

 the stalk of the sporangiophore, with mean diameter 45-60/1, maximum 

 70/1, minimum 10-20^; membrane of sporangium smooth, hyaline, trans- 

 parent, diffluent, leaving a basal collarette; columella large, hemispherical 

 or globose, io-20/i, smooth (or supplied with short spines), gray, fuligi- 

 nous, or brown-black. The apophysis and the pedicel have also the same 

 tint. Spores are globose, subglobose, or more rarely oval, hyaline, small, 

 for the major part 2 by 3/i (some larger, 4 by 6.5)u). Zygospores unknown.

Vegetative hyphae blue-violet, continuous, bi;anching, unequal, some- 

 times nodular; sporangiophores solitary, borne directly on the mycelium, 

 attaining 25 mm. in length, terminated by an infundibuliform apophysis, 

 with septum 12-241JL from summit; sporangia uniform, globose, 36-42/x, 

 passing from pale violet to grayish black and then to brown ; membrane of 

 sporangium smooth, diffluent, leaving a basal collarette; columella hem- 

 ispherical or obconical, often sunnounted by a nipple; spores numerous, 

 small, smooth, pale violet, globose, 4-7^; zygospores 6o)U in diameter, 

 brown, globose, rugose-verrucose ; suspensors straight, widening into a 

 funnel, provided with 10-20 long, slender (7^1 thick) circinate appendages 

 disposed in a single verticil; azygospores equal; chlamydospores smooth, 

 intercalary. 



Hab. Humous soil from wood near Bussimn, Holland, Koning.
