FIG. 15. i , basidiospore of Collybia radicata. 2, ascospore of Delitschia 

 maravica, i -septate, and surrounded by a colourless gelatinous coat. 3, 

 ascospore of Delitschia insignis, i-septate, and with a hyaline appendage 

 at each end. 4, ascospore of Sporormia ovina, 3-septate, and surrounded 

 by a hyaline gelatinous coat. In the right-hand figure the gelatinous 

 sheath has disappeared, and the spore has broken up into four component 

 cells. 5, ascospore of Sporormia fimefaria, multiseptate. 6, chain of 

 conidia of Cysiopus candidus, showing the narrow necks connecting the 

 conidia, which dissolve in water at maturity, liberating the conidia as a 

 powdery mass. 7, very young progametes of Sporodinia aspergillus. 8, 

 the same in an older stage ; the progametes have come in contact with 

 each other, and a portion containing the protoplasm and nucleus has 

 been cut off from each of the gametes, these two gametes eventually forming 

 the zygospore. 9, mature zygospore of same, the empty progametes, now 

 termed suspensors, finally decay, liberating the zygospore. 10, chlamy- 

 dosporesof Chlamydomucor, formed interstitially in the length of a hypha. 

 11, zoospores of Phytophthora infestans. 12, oosphere of Diplanes sapro- 

 legnoides, showing perforations in the wall, and containing seven oospores, 

 antheridium attached to wall on the right (after Leitgeb). 13, spore of
