We assume this plant is the diploid Asplenium trichomanes based upon habitat; it is growing in serpentine tallus. Apart from spore size, it is nearly indistinguishable from A. quadrivalens (=A. trichomanes subsp. trichomanes), however that species is restricted to limestone and other alkaline buffered substrates.
