occur on oak-branches, etc., resembling this and C. Sambuci.
They require further study before proposing them as species.
Thelephora cretacea. P., and T. dryina. P., belong to these indeterminate
species, and are both found in this country ; the
former on deal in hothouses, the latter on oak-branches.
13. C. lividum, P .; effused, agglutinate, waxy, soft, smooth,
