PLATE II. 
Fig. 5. The many-celled archicarp of Collema micropJiyllum. The coiled 
ascogonium passes into the erect trichogyne, which in turn extends above the sur¬ 
face of the algal-host colony, x 300. From Stahl. 
Fig. 6. The many-celled archicarp of Miss Bachman’s Collema-Wko. plant. 
The coiled ascogonium is at the left, and the trichogyne extends to a group of in¬ 
ternal spermatia (antheridia?) at the right, x 520. From Miss Bachman. 
Fig. 7. A mature archicarp of Ascoboliis carbonarius: a, a conidium which 
gives rise to an archicarp; b, the conidiophore; d to g, the stalk of the archicarp; g 
to j, the ascogonial coil; h, probably the ascogonium proper; k to m, the trichogyne; 
m, the antheridial conidum; n, the conidiophore. x 400. From Dodge. 
Fig. 8. The archicarp of Peltigera canina. One of four cells of the ascogonium 
is shown at A, and a cell of the vegetative hypha from which the archicarp arose is 
shown at s. There is supposed to be no trichogyne. x 750. From Funfstuck.
