A Synopsis of Plant Pliyla 31 



Family loi. Elaphomycetaceae. Spore-fruits subterranean, 

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



Family 102. Terfeziaceae. Spore-fruits subterranean, open- 

 ing irregularly, not pulverulent when ripe. Tcrfesia. (Pf. I, 



I, 312.) 



Order Exoascales. True fungi, typically parasitic, much re- 

 duced and simplified, the branching mycelium bearing single or 

 clustered asci, not forming genuine apothecia. 



Family 103. Exoascaceae. Parasitic in the tissues of higher 

 plants, producing crov^ded asci which break through the epi- 

 dermis. Exoascus, Taphrina. (Pf. I, i, 158.) 



Family 104. Ascocorticiaceae. Saprophytic, the asci forming 

 a cushion on the abundant mycelium. Ascocorticinm. (Pf. I, 

 I, 161.) 



Family 105. Endomycetaceae. Parasitic or saprophytic, the 

 asci single, not clustered in masses or cushions. Eremascns, En- 

 domyces. (Pf. I, i, 154.) 



Order Hemiascales. True fungi mostly saprophytic, much 

 reduced and simplified, the branched mycelium bearing the single 

 few- to many-spored asci. 



Family 106. Ascoideaceae. Asci much elongated, not corti- 

 cated. Ascoidea. (Pf. I, i, 145.) 



Family 107. Protomycetaceae. Asci ellipsoid or spherical, not 

 corticated. Protomyccs (parasitic), Endogonc. (Pf. I, i, 147.) 



Family 108. Monascaceae. Asci spherical, terminal, corticated. 

 Monasciis. (Pf. I, i, 148.) 



Family 109. Saccharomycetaceae. Asci early isolated from 

 the few-celled mycelium, which itself early breaks up into short 

 segments; saprophytic. Sac char omyces. (Pf. I, i, 153.) 



Class 16. TELIOSPOREAE. Parasitic fungi, much reduced 

 and degraded, with a mycelium which penetrates the tissues of 

 the host and produces erumpent spore-clusters (sori) but no defi- 

 nite spore-fruits ; conidia single-celled, usually of one or two 

 kinds; asci ("telioasci") reduced, containing one, two, or several 

 ascospores ( "teliospores" ) .
