spores in various stages of development; 4, A. carhonarius. Drawing of a 

 portion of an ascus with isolated spores; 5, A. immersns. Drawing of an

Plate 8 (p. 98) 



Upper figure (1). Aleuria aurantia. Photograj)h of a number of 

 apothecia, about natural size. At the right, a drawing of an ascus with 

 mature spores showing reticulate markings and a paraphysis with rather 

 strongly enlarged tip. Below, two immature spores. 



Lower figure (2). Aleurina atrovinosa. Photograph of a cluster of 

 apothecia, about natural size. At the left, a drawing of an ascus with mature 

 spores showing irregular reticulations and a paraphysis with enlarged tip. 

 Above, two immature spores. 



Plate 9 (p. 102) 



Upper figure (1). Aleuria rutilans. Photograph of several apothecia 

 at different stages in their development and showing habitat among mosses. 

 Above, drawing of a mature and an immature spore, the former showing the 

 regular and fine reticulate markings. 



Lower figure (2). Aleuria rhenaua. Photograph of several apothecia 

 showing habitat in coniferous woods and dense mycelial growth which binds 

 the substratum together. Above at the right, a mature and an immature 

 spore, the former showing the typical reticulate markings. 



Plate 10 (p. 110) 



Pyronema omphalodes. Photograph of a mass of mycelium and apothecia, 

 showing the natural habitat on charcoal (a). Upper right-hand corner, a 

 germinating ascospore showing the very coarse mycelium (c). Lower right- 

 hand corner, cluster of oogonia with trichogynes (d). Lower left-hand corner, 

 antheridium and oogonium with the connecting trichogyne (e). Upper left- 

 hand corner, an ascus with spores and a paraphysis (b).

 decimsporus; 2-3, Streptotheca woolhopensis, the latter showing the method of 

 dehiscence of the ascus; 4, Streptotheca obscura; 5, Ryparobius polysporus; 

 6, Ryparobius monascus; 7, Thecotheus Pelletieri, showing the large size of 

 the asci and spores.
