GOSSIP NIGHT. 



Objects Exhibited and Notes. 



{July 2GfJi, 1910.) 



A. E. Hilton : Sporangia of Arcyria punicea^ x 20, showing 

 the ehxstic network of the expanded capillitia, after dispersion 

 of the spores. Part of a gathering found among moss. The 

 sporangia had formed partly on the moss and partly on the sandy 

 surface of the mould in which the moss was growing. 



(Avffust 9tJi, 1910.) 



A. E. Hilton : Lamproderma arcyrionenia, x 20. The brilli- 

 ant sporangium walls are membranous and evanescent, and fall 

 away in large fragments. A portion sometimes persists as a 

 collar round the base of the sporangium. Found among moss, on 

 sandy and matted soil. 



{Reptemler 13a, 1910.) 



A. E. Hilton : Sporangia of Badhamia foliicola, x 20. These 

 were formed by the revived sclerotium of a plasmodium, which 

 had crept up a hop-pole and dried there. In B. foliicola there is 

 less lime than in B. utricidaris, and the specific characters vary 

 accordingly ; whether this justifies uniting the species is doubtful. 



{September 21th, 1910.) 



A. E. Hilton : Capillitia of Arcyria flava, x 20. While en- 

 closed within the sporangium wall the fibres of the capillitium 

 are bent and folded in every direction ; when the sporangium 

 dries after maturing, the fibres straighten and stiffen, so that the 

 meshes of the network become larger; the capillitium expands 

 to a remarkable length and the spores are scattered.
