with C exhibiting the expanded capillitium network; E, some of the 

 spores (seeds of MicheH). F and G, Clavaria ( = Clavaria fragilis 

 Fr.); F, fruit-bodies; G, spores. H, Lycoperdon ( = Lycoperdon 

 plumhea Fr.) with spores coming out through the stoma of the en- 

 doperidium; six capiUitium fibres shown above. I-K, Carpobolus 

 { = Sphaerobolus stellatus Tode) ; I, fruit-bodies natural size on a piece 

 of wood, the dotted Hues indicating the direction of flight of several 

 peridiola; J, part of a drawing showing two fruit-bodies on a stick 

 enlarged, on the left a section exhibiting the two layers of the stellate 

 peridium containing a peridiolum before discharge, on the right a 

 fruit-body in which the inner layer of the peridium has suddenly 

 become inverted and has shot forth the peridiolum as indicated by 

 the dotted line; K, spores from the interior of a peridiolum. L, 

 Fungoides {=Peziza sp.) with the spores puffing out into the air. 

 M, N, Lichen-Agaricus ( = Sphaeria sp. ?); M, five perithecia much 

 enlarged ; N, three rows of eight spores each, each row having doubtless 

 been seen in an ascus. O, P, Lichenoides ( = Pertusaria communis?), 

 enlarged drawings from a lichen; O, some perithecia showing the 

 stomata and asci; P, two isolated asci. A, from Micheli's Tab. 

 96; B-E, from Tab. 94; F, G, from Tab. 87; H, from Tab. 97; I-K, 

 from Tab. 101 ; L, from Tab. 86; M, N, from Tab. 55 ; O, P, from Tab. 

 56. 



Plate IV. 



Figures illustrating the Moulds and material which Micheli 

 employed in his classical experiments on reproduction. Macroscopic 

 and microscopic appearance: A and B, of Miicor vulgaris, capitula 

 lucido, per matiiritatem nigro, pediculo griseo { = Mucor Mucedo Linn.); 

 D, of Aspergillus capitatus, capitulo glauco, seminihus rotundis {=As- 

 pergillus glaucus Link); E, Aspergillus albus, tenuissimus, graminis 

 dactyloides facie, seminibus rotundis { = Pencillium digitatum Sacc.) ; 

 and F, G, Botrytis ramosa, cinerea, seminibus rotundis { = Botrytis 

 umbellata Fr.). In B: a, an unopened capitulum ( = sporangium) ; 

 b and c show the internal cavities, and d the semina ( = spores) emerging. 

 C, the placenta (^columella) of a capitulum. H, a chain of semina 

 ( = spores) from an Aspergillus. I, the semina separated. J, a piece 

 of melon in the shape of a triangular pyramid on the faces of which 

 three different kinds of Moulds (B, D, and G, Mucor, Aspergillus, and 

 Botrytis) were sown and have sprung up. K, a piece of quince in the 

 form of a truncated pentagonal pyramid, with five crops of Moulds. 

 L, a piece of a pear in the form of a truncated hexagonal pyramid 

 with six crops of spores. A-C, J, K, L, from Micheli's Tab. 95; 

 D-I from Tab. 91.
