Ellen M. Dallas

Ellen M. Dallas, also listed as Ellen Markoe Dallas, was an American botanist born in 1837 and died in 1908. She is chiefly remembered as the coauthor of Among the Mushrooms: A Guide for Beginners, a work written with Caroline A. Burgin.

That book, first published in 1900, introduces readers to mushroom structure, habitats, and identification in a clear, accessible way. Its beginner-friendly tone is a big part of why it has continued to circulate through libraries and digital editions long after its original publication.

Reliable biographical details about her life are fairly limited in the sources I could confirm, so it is safest to remember her through the book itself: a patient, practical introduction to fungi from the turn of the twentieth century.
