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. Körber’s term foramerispore. 
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. 
Sporogenouslayer. Same as hymenium. 
Sporophore (Fruchtträger). Branch or 
portion of thallus which bears spores or 
spore-mother-cells. Same as recepta- 
culum of Leveillé, 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. 
Sporula. Old term for what is designated 
above as spore. 
Sprout-cell. Cell produced by sprouting. 
Sprout-chain. Chain of cells produced by 
sprouting. 
Sprout-gemma. 
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 cylindrica] 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. 
In Mucoreae: same 
Filamentous Fungus, Compound 
Fungus-body. | 
Sterigma. (a) Same as basidium. (2) 
Stalk-likebranch 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.

body.
