CYTOLOGY OF EOCRONARTIUM MUSCICOLA 
419 
Fig. 36. The chromosomes moving toward the poles; anaphase. 
Fig. 37. Telophase: nucleolus at one pole. 
Fig. 38. An elongated, binucleate basidium. 
Fig. 39. Second nuclear division, one nucleus dividing more rapidly than the 
other. 
Fig. 40. A two-celled, four-nucleate basidium. The middle septum is always 
the first formed. 
Fig. 41, A three-celled basidium. The second mitosis in this basidium was 
evidently not exactly simultaneous in the two nuclei. Consequently one septum is 
partially formed while the other has not yet appeared. 
Fig. 42. A typical four-celled basidium. 
Fig. 43. A mature four-celled basidium which is beginning to form a sterigma 
from the apical cell. 
Figs. 44, 45. Mature basidia forming sterigmata. 
Figs. 46-58. Sterigmata and spore formation. 
Fig. 46. A completely formed sterigma with an acuminate tip. 
Fig. 47. Sterigma at the tip of which the spore "initial" is beginning to form. 
Figs. 48-50. Stages in the enlargement of the young spore. The sterigma in 
each case contains a normal nucleus. 
Figs. 51-53. The passage of the nucleus into the spore. It is drawn out into 
a long, irregularly beaded rod. 
Figs. 54-55. Stages in the transformation of the nucleus from the deep- 
staining rod into its normal form. 
Fig. 56. Normal nucleus in a nearly mature spore. 
Fig. 57. Mature spore attached to the sterigma. 
Fig. 58. Mature, detached spore. 
Figs. 59-61. Spore-germination. 
Fig. 59. Early stage in spore germination; germ-tubes formed at both ends 
of the spore. This spore germinated on the sporophore in wet weather. 
Figs. 60-61. Spores induced to germinate in hanging drop culture. The 
apparent septa are merely dried hyaloplasm.
