SPORE, the reproductive cells in Agarics borne four ou each basi- 

 diuin: more accurately called basidio-spores. In other crypto- 

 gams the term is applied to reproductive cells or bodies of a great 

 variety of kinds. The basidio-spores when they germinate give 

 rise to mycelium. 

 _ SPOROPHORE, fruit-body. 

 SPURIOUS, false. 



SQUAMOSE, (of pileus or stem), covered with scales. 

 SQUAMULOSE, minutely squamose. 

 SQUAMULE, scale. 



SQUARROSE, (of pileus and stem), covered with recurved scales. 

 STAINED, said of any part which appears as if some coloring 



matter had been spilled on it and spread on the surface. 

 STALK, an indefinite term for stem, pedicel, etc. 

 STELLATE, (of spores, scales), with extensions like that of a star. 

 STERIGMA, the tiny spicule-like extension at the apex of a basi- 



dium on which the spores develop. 

 STERILE, said of a fruit-body orhyinenium which is immature or 



produces no spores ; or simply, without spores. 

 STERILE CELLS, term applied in this report to the slender cells 

 on the edge of gills which bear no spores and which cause the 

 fimbriate appearance of the edge as shown under a lens. 

 STIPE, technical term for the stem of muslirooms; see stem. 

 STIPITATE, possessing a stem. 

 STOUT, (of stem), relative to slender; not so many times longer 



than thick. 

 STRAIGHT, (margin of pileus), when not incurved. 

 STRAMINEOUS, straw-color. 

 STRIATE, (of margin of pileus), radiating minute furrows or 



lines; (of stem), longitudinal lines or minute furrows. 

 STRIAE, the lines or furrows when striate. 



STRIGOSE, (of pileus or stem), with coarse or thick, long, rather 

 stiff hairs. 



STUFFED, (of stem), when the axis is filled with a differentiated 

 pith which usually disappears in age leaving it hollow. 



SUB—, prefix signifying "almost," "somewhat" or "under." 



SUBGENUS, a term in classification ; a grouping under a genus and 

 containing groups of related species. The subgenera of the my- 

 cologists of one generation are often raised to the rank of genera 

 by later students. 



SUBICULUM, a more or less dense felt of hyphae coverino- the sub^ 

 stratum, from which the fruit-bodies arise.
