FUSARIUM. 



I. ScHizoMYCETES. Consisting of 

 threads which break up into minute cylin- 

 drical bodies, sometimes straight, some- 

 times curved, or microscopic globular par- 

 ticles ; in the former case, sometimes at 

 length swarming and forming a cloudy 

 gelatinous mass : in solutions or in decom- 

 posing substances. 



II. Phycomycetes. Aquatic or epi- 

 phytous, propagated by zoospores, or by 

 oospores arising from fertilization. 



1. Saproleynice. Aquatic. 



2. Pero7iosporece. Epiphytic. 



3. Mucorini, Fermentigerous ; Sapro- 

 phytic (Moulds). 



III. ' Hypodeemle. Epiphyllous.

2. (Jstilaginece. \ 



IV. Basidiomy'cetes. Spores seated 

 upon Basidia or Sporophores arising from 

 a distinct hymenium. 



1. TremelliiKB. Tissues gelatinous; hy- 

 menium exposed. 



2. Hymenomxjcctes. Tissue cellular, hy- 

 menium inferior (Mushrooms &c.). 



3. Gasteromycetes. Hymenium intri- 

 cate, cellular, internal (Puff-balls &c.). 



V. AscojiYCETES, Sporidia contained 

 in Asci (thecse). 



1. Protomyces. More properly perhaps 

 associated with Peronosporese. 



2. TuberacecB. Hymenium as in Gas- 

 teromycetes (Truffles &c.). 



3. Onyijenece. On animal substances, 

 very rarely on decayed wood. 



4. Fyrenomycetes. Asci contained in 

 perithecia. 



5. Discomycctes. Hymenium superior, 

 disciform. 



VI. Myxomycetes. Spores amoeboid 

 in germination, subsequently conjugating.

FUNGUS-BED.— Mycologists _ find this 

 very useful for growing the microscopic 

 Fungi. It is best made of a small wooden 

 box half-filled with damp bog-earth, and 

 covered with a plate of glass. In winter it 

 should be kept in a warm room. 



FURCELLA'BIA, Lamx.— A genus of 

 Cryptonemiacese (Florideous Algae), cou- 

 taixiing one common British species, growing 

 on rocks and stones between tide-marks, 

 consisting of a fastigiate, dichotomously- 

 divided frond, 6 to 12" high, of a brownish- 

 purple colour, and somewhat cartilaginous 

 texture. The teti-aspores, which are linearly 

 arranged, are imbedded in the periphery of 

 the swollen pod-like extremities of the 

 branches. Conceptacular fruit as yet un- 

 known.

FURCULARIA, Lam.— A genus of Ro- 

 tatoria, of the family Hydatinsea. 



Char. Eye single, frontal ; tail-like foot 

 forked. Several species ; all freshwater but 

 one, Avhich is marine. 



F. Reinhardtii, E. (PL 43. fig. 34: fig. 35, 

 teeth). Body fusiform, truncated in front ; 

 foot elono-ate, cj'lindrical ; toes two, short ; 

 length 1-120". 



Found creeping upon Laomedea geni- 

 cidata. 



F. gibha. Body oblong, slightly com- 

 pressed, dorsally convex, ventrally flat ; 

 toes stvliform, half as long as the body ; 

 length 1-96". Freshwater.

FUSA'RIUM, Lk.— A genus of Stilbacei 

 (Hyphoraycetous Fungi), not very satis- 

 factorily distinguished from Fl'Sisporium ; 

 but having a firm, cellular, pulvinate, fleshy 

 stroma, upon which thespoi'es are borne on 

 distinct sporophores glued together into an 

 erumpent discoid stratum. P. tremelloides 

 is common, forming roundish orange-red 

 spots on decaying nettle-stems ; but it is 

 now believed to be a spore-bearing state of 

 Peziza fusarioides. F. roseum forms little 

 gregarious red dots on the stems of beans, 

 Jerusalem artichokes, and other plants.
