ci/ 1 hub- lea, Bull., Lycogala epidendrum, Buxb., Dermodium 

 conicum, Pers. 



B. — The portion without the fine net-work having a very 



wide-meshed net-work and with an irregular outline, Siphopty- 



chium Casparyi, Rki., Tubulina dipihtta, B. &. Rav. 



10. — Thickenings in the shape of a delicate, fine-meshed net-work 



covering about two-thirds of the surface, the remaining portion with 



scattered warts and ridges ; the warted portion having the sharp, 



regular outline of a wide spindle, the ends of the spindle lying at 



the poles of the sphere, JEnteridium Rozeanum, Rki. 



11. — Thickenings in the shape of a delicate fine-meshed net-work 

 covering about one-half of the surface, the remaining portion with 

 scattered warts and ridges ; the warted portion having a sharp, 

 regular, circular outline, Reticularia Lyeoperdon, Bull. 



It will be seen from this series how readily the rather complex 

 sculpturing of numbers 9, 10 and 1 1 might have had its origin from 

 a simple warted type by the gradual coalescence of the warts in 

 certain directions. 



Note on Orthotrlcha. — Mr. Harold Wingate also remarked 

 that in the Journal of Mycology for November, 1886, he had de- 

 scribed a new genus of Myxomycetes under the name of Orthotrlcha. 

 In some of the journals which noticed the article the genus was 

 mentioned as Orthotrichia, and in Saccardo'sSyllogeFungorum, vol. 

 vii, part i, this error was repeated. It is inferred that it was done 

 in error as no mention is made of any intention to correct the origi- 

 nal name. As the original name conflicted with that of a genus of 

 mosses, the speaker had concluded to adopt the orthography as given 

 in Saccardo: — Orthotrichia instead of Orthotricha.
