20 Cliaiics 11. Bcsscy 



liaceous, variously forketl or laterally branched, more or less tila- 

 nientous internally. Scliizymcnia, Xciiiastouia. {^Vi. i, 2, 521.) 

 Family 22. Rhizophyllidaceae. i'lants terete or compressed, 

 sometimes articulate-constricted, sometimes creeping; structure 

 mostly iilamentous. CJioiidrococciis, RhizophyUis. (i'f. I, 2, 



Family 2^. Squamariaceae. L'lants usually minute, foliaceous, 

 or crustiform, attached by rhizoids on their lower surface, usually 

 encrusted with lime. PcyssoncUia. (P£. I, 2, 532.) 



Family 24. Corallinaceae. Plants from filamentous, more or 

 less branched (and then jointed) to foliaceous or crustaceous, al- 

 ways encrusted with lime. Corallina, Mclohcsia. (Pf. I, 2, 537.) 



Class 14. CHAROIDEAE. Antheridial branches compounded 

 into a globular structure containing many sperm-bearing fila- 

 ments, the true antherids ; sperms biciliated ; oogone rounded, 

 covered with a twisted layer of protective cells : no trichogyne. 

 Green plants. 



Order Ciiarales. Plants consisting of erect, branching stems, 

 bearing whorled branches. Stems and branches composed of 

 large, long cells which are often covered (corticated) with smaller 

 cells. 



Family 25. Nitellaceae. Crown of oogone composed of ten 

 cells. NitcUa, Tolypclla. (Pf. I, 2, 172.)

 (Pf. I, 2, 174.) 



Phylum VII. CARPOMYCETEAE. The Higher Fungi. 



Plants terrestrial or aerial, filamentous, sometimes compacted 

 into a definite plant body, always destitute of chlorophyll, and so 

 parasitic or saprophytic ; propagation 1iy the scjxiration of special 

 cells (conidia), and the production of thick walled cells (chlamy- 

 dospores) in the plant body; generation (where known) by the 

 union of the protoplasm of an anthcricl with the protoplasm (egg) 

 of an oogone. and the production of a fruit-body (spore-fruit, or 

 sporocarp) consisting of sporogcnous and sterile tissues.
