A letter to Clinton from Charles Peck (Rhoda did not write during this month):


Vol. 3 No. 210 [M 12]

                            Albany, Dec. 20th 1866


My Dear Sir;


The little “Fissidens on clay,” which you sent I consider F. minutulus, Sulliv. F. exiguus has no pellucid border to the leaf: your specm. have. F. minutulus and F. bryoides both have the pellucid border but the former is dioecious, the latter, monoecious. F. bryoides generally grows on ground while F. minutulus is said to grow on rocks, but as I can not find a single male flower in your specims. I think it is F. minutulus in spite of its place of growth. The male flowers are generally plenty and axillary in F. bryoides, by which, with its rather larger size, I separate it from F. minutulus.


The little F. exiguus was collected in Schoharie and sent me by Miss R. Waterbury. My remark concerning it was made because I thought she might have sent you specms.under the erroneous name. I first gave it for her. I put the bit with your specimens that in case she had done so you might see to what I referred. I send a label for it, if there is enough of it to make a specm. Also a bit of F. bryoides.


            Very truly yours

Peck strongly advocated the close association of a particular moss species with its substrate as an indicator of its identity. As indicated elsewhere, These two species are presently combined in a Fissidens bryoides Hedw. complex (H. Crum & L. Anderson, Vol. 1 Mosses of Eastern North America,  1981, Columbia University Press. The sexuality of specimens in the complex is dioicous, synoicous or autoicous, the latter with male buds basal or axillary (p. 102)
