5. Toruloidea candidula (Sacc.) 
Oospora candidula Sacc. Michelia 2 : 545. 1880. 
Pulvinate or effused, white; mycelium creeping, branched; 
sporophores erect, simple or branched ; spores in long chains, 
hyaline, ovoid or obovoid, 3 X 
On various substances. 
Specimens examined: New Jersey, Ellis and Harkness. 
The specimen is in the New York Botanical Garden and marked 
Oospora hyalinula Sacc. 
PoLYSCYTALUM Riess. Bot. Zeitung ii; 138. 1853 
Original description : Flocci erecti, subrigidi, ramosi ; sporae 
simplices, cylindricae in catenas ramosas, ex floccorum ramorum- 
que apicibus natas seriatae. 
Mycelium wanting, or at least not differing from the sporo- 
phore ; sporophores simple or branching, septate, hyaline or 
slightly colored; spores borne in chains at the ends of the sporo- 
phores, cylindric, obtuse at each end. 
Type species, Polyscytalum fecundissimnm Riess. 
The difference between this genus and Cylindrium is based on 
the development of the mycelium. In the latter it is not so well 
developed. This distinction scarcely constitutes a generic differ- 
ence and there seems no good reason for maintaining the two 
genera.
