What reading level is Researches On Fungi volume 1 book?
To quickly assess the difficulty of the text, read a short excerpt:
2 Brefeld, loc. Cit. , pp. 65, 66. THE VIOLENT PROJECTION OF SPORES 135 Coprinus and of many other genera goes, are never shot off simul- taneously. I have also not been able to obtain any evidence that the spores are projected forwards owing to ejaculation of the contents of the basidia. The mechanism of spore-discharge, however, will be discussed more conveniently in the next chapter. Several methods have been used to determine whether or not the spores are shot off the sterigmata. The first ...one, which seemed for some time to give convincing evidence of spore-projection, led to the discovery of an unexpected optical illusion. Method I. The first method employed for observing spore-fall microscopically was that of placing hymenial surfaces in vertical planes and observing them from above with an ordinary upright microscope. Through the middle of some of the hymenial tubes of a freshly grown fruit- body of Polyporus squamosus, a transverse section 1-2 mm. Thick was made (Fig. 47). This was then placed on a glass slide, covered with a cover-glass, and looked down upon from above with the low power of the micro- scope.
