EXPLANATION OF TERMS. 



pound spore, spora composita, septate 

 spore, semen multiplex, multilocular 

 spore (spora multilocularis), cellular 

 spore (spora cellulosa), pluricellular 

 spore. 



Sporidium. Spore abjointed on a promy- 

 celium. 



Sporiferous. Bearing spores. 



Sporoblast. Korber's term for a meri spore. 



Sporocarp (sporocarpium). Pluricellular 

 fructification, i. e. pluricellular body de- 

 veloped as the result of the sexual act 

 from an archicarp alone or from adjacent 

 hyphae as well, unlike the body which 

 produced the archicarp, and essentially 

 serving to the formation of spores. See 

 fructification. 



Sporogenous. Producing spores. 



Sporogenous layer. Same as hymenium. 



Sporophore (Fruchttrager). Branch or 

 portion of thallus which bears spores or 

 spore-mother-cells. Same as recepta- 

 culum of Leveille*, encarpium of 

 Trattinick. Its forms are distinguished 

 as gonidiophore, sporangiophore, ba- 

 sidiophore, ascophore, &c. 



Sporophyte. In Archegoniatae : the seg- 

 ment in the life-cycle which produces 

 spores.

 above as spore. 



Sprout-cell. Cell'produced by sprouting. 



Sprout-chain. Chain of cells produced by 

 sprouting. 



Sprout-gemma. In Mucoreae : same 

 as chain-gemma. 



Sprout-germination (Sprosskeimung) . 

 Germination of a spore in which a small 

 process (germ-cell), with a narrow base, 

 protrudes at one or more points on the 

 surface of the spore, then assumes an 

 elongated cylindrical form, and finally is 

 abjointed as a sprout-cell. Comp. tube- 

 germination. 



Sprouting. Formation of an excrescence 

 with a narrow base, and of the same 

 character as the parent, at one or more 

 points on a cell, which after enlargement 

 is delimited by a transverse wall either 

 before or after reaching its proper size. 

 Same as pullulation. 



Sprouting-fungus (Sprosspilz). Growth- 

 form in which the thallus consists of a 

 sprouting-cell or chain of sprouts. Comp. 

 Filamentous Fungus, Compound 

 Fungus-body. 



Sterigma. (a) Same as basidium. (b) 

 Stalk-like branch of a basidium bearing a 

 spore, (c ) Cell from which a spermatium 

 is abjointed. 



Sterile basidium. In Hymenomycetes : 

 body in the hymenium like a basidium but 

 non-sporiferous and possiblya paraphysis. 



Stipe (stipes). General term for the stalk 

 of a sporophore. 



Strand. See mycelial strand. 



Stratum corticale. See rind. 



Stratum gonimon. Same as algal 

 layer. 



Stratum medullare. See medulla. 



Stroma. Compound Fungus-body having 

 the form of a cushion, crust, foliaceous ex- 

 pansion, or erect unbranched or branched 

 shrub-like body. Same as receptaculum. 



Stylospore. Same as pycnogonidium. 



Suberification. Same as suberisation. 



Suberisation. Transformation of a cell- 

 wall into suberin, i. e. conversion into 

 cork. Same as suberification. 



Subhymenial layer. Same as hypo- 

 thecium. 



Subulate. Awl-shaped. 



Suspensor. In Mucorini ; club-shaped or 

 conical portion of hypha adjoining a 

 gamete-cell after its delimitation. Same 

 as zygosporophore. 



Swarmcell. Motile naked protoplasmic 

 body. 



Sycosis. Disease of the skin due to the at- 

 tack of Microsporon Audouini, Rob., and 

 Microsporon mentagrophytes, Rob. Same 

 as mentagra parasitica. 



Symbion. Organism which lives in a state 

 of symbiosis. 



Symbiosis. Living together of dissimilar 

 organisms. 



Symphyogenetic. Formed by union of 

 previously separate elements. 



Sympodial. Of thenature of a sympodium. 



Sympodium. An axis made up of the bases 

 of a number of successive axes arising 

 as branches in succession one from the 

 other. Comp. monopodium. 



Tela contexta (Filzgewebe). Weft of 

 distinct hyphae. Same as felted-tissue. 



Teleutogonidium. Same as teleutospore. 



Teleutospore. InUredineae: spore formed 

 by abjunction on, but not separating from, 

 a sterigma, producing in germination, 

 which takes place after a resting period, 

 a promycelium. 



Tetraspore. In Rhodophyceae : one of 

 the spores formed by division of a mother 

 cell into four parts. 



Thallodic. Belonging to the thallus. 



Thallus. A vegetative body without dif- 

 ferentiation into stem and leaf. In Fungi 

 is the whole body of the plant not serving 

 directly as an organ of reproduction.
