DESCRIPTION OF PLATE XL 



Illustrating Mr. Currey's paper on the Reproductive Organs 

 of Fungi, 



Fig. 



1. — A stellate spore o^ Stilhosjjwa militaris, magnified 500 diameters. 

 2. — An abnormal spore of the same, magnified 350 diameters. Two of 



the horns have failed to grow. 

 3. — The apex of a filament and fascicle of spores of StUhospora militaris, 



magnified 500 diameters. 

 4. — The apex of another filament and fascicle, magnified 350 diameters. 

 5. — A vertical section of a pulvinulus of StUhospora militaris, magnified 



60 diameters. 

 6. — Conidia of StUhospora militaris, magnified 500 diameters. 

 7. — A fascicle of StUhospora militaris, throwing out a germ-filament. 



Magnified 350 diameters. 

 8 and 9. — Asci and sporidia of the Sphwria accompanying Steganosporium 

 cellulosum. It is probably Sp>hckria amhlyospora. Magnified 220 

 diameters. 



The ascus, fig. 9, is in an eai-lier stage than fig. 8, the sporidia 

 being of a paler colour, and the gelatinous envelope not 

 developed. 

 10 to 15. — -Varieties of sporidia of Steganosporuim cellulosum., magnified 



220 diameters. 

 IG and 17. — Empty asci borne upon the stratum proliferum of Stegano- 

 sporium cellulosum. The internal second membrane is very 

 visible. Magnified 220 diameters. 

 18 and 19. — Bodies also borne upon the stratum proliferum of the Stegano- 

 sporium.. The endochrome is divided into eight portions, being 

 apparently imperfect sporidia. Magnified 220 diameters. 

 20 and 21. — Ripe sporidia of Sphcerict amhlyospora, magnified 220 dia- 

 meters. 

 22, 23, and 24. — Spores of Steganosporium cellulosum at the commence- 

 ment of germination. Attached to one of the germ-filaments is 

 a globular vesicle, possibly adventitious. Magnified 220 dia- 

 meters. 

 25. — A sporidium of Steganosporium cellulosum after about three days' 



germination. Magnified 220 diameters. 

 2G. — An ascus and sporidia of Splia^ria cryptosporii, magnified 220 dia- 

 meters. 

 27 and 28. — Stylospores or perhaps imperfect asci of the same Sphceria, 



magnified 220 diameters. 

 29, 30, and 31. — Abnormal asci of Sp>hceria cryptosporii. The contents 

 are granular, but thei'e is no symptom of the formation of sporidia. 

 Magnified 220 diameters. 

 32 and 33. — Curious instances of dehiscence of the asci of Sphceria her- 

 barum. In fig. 32 the second membrane is clearly visible at both 

 ends of the broken ascus. In fig. 33 the second membrane is 

 reduced to a string, and encloses a single sporidium. Magnified 

 220 diameters.
