It surrounds them, as a spider its prey, with a fibrous net of narrow meshes, which is gradually converted into an impenetrable covering ; but...

JM Crombie has therefore our sympathies in the remark with which his summary of the gonidia controversy closes, in which he characterizes it as a " sensational romance of lichenology," of the " unnatural union between a captive algal damsel and a tyrant fungal master.
