Revisions of Some Plant Phyla 23 



Family 96. Perisporiaceae. Mostly saprophytes with the yel- 

 low or black fruits usually without appendages. Parodiella, Peri- 

 sporium. (Pf. I, i, 333.) 



Family 97. Microthyriaceae. Minute superficial parasites upon 

 higher plants, the filaments dark-colored ; spore fruits flattish. 

 unappendaged, contaning 8-spored asci. Microthyrium, Asterina. 

 (Pf. I, I, 338.) 



Order Aspergillales. Little Truffles. True fungi, sapro- 

 phytic, with an abundant branching mycelium which grows super- 

 ficially, or penetrates the substratum, and eventually bears the 

 small, mostly spherical, fleshy spore-fruits. 



Family 98. Gymnoascaceae. Spore- fruits usually mere loose 

 masses of hyphae with asci in the center. Gymnoascus, Myxo- 

 trichium. (Pf. I, i, 293.) 



Family 99. Aspergillaceae. Spore-fruits spheroidal, paren- 

 chymatous, with a definite peridium, sessile, not subterranean, 

 opening irregularly. Aspergillus, Penicillium, Meliola. (Pf. I, i, 

 297.) 



Family 100. Onygenaceae. Spore-fruits spheroidal, paren- 

 chymatous, with a definite peridium. stalked, not subterranean. 

 Onygena. (Pf. I, i, 309.) 



Family loi. Trichocomataceae. Spore- fruits cylindrical, erect, 

 with a peridium, sessile, not subterranean. Trichocoma. (Pf. 

 I, I, 310.) 



Family 102. Elaphomycetaceae. Spore-fruits subterranean, 

 opening irregularly, pulverulent when ripe. Elaphomyces. (Pf. 

 I, I, 3II-) 



Family 103. Terfeziaceae. Spore-fruits subterranean, open- 

 ing irregularly, not pulverulent when ripe. Terfezia, Choir 0- 

 myces. (Pf. I, i, 312.) 



Order Hemiascales. True fungi, mostly saprophytic, much 

 reduced and simplified, the branched mycelium bearing the single 

 few- to many-spored asci.
