Summary:
Features include very thin, waxy fruitbodies that are pale grayish or lilaceous to obscurely rosy, growth on hardwood, and microscopic characters including crescent-shaped spores.
Tulasnella allantospora has been found in ON, PQ, AZ, IA, MA, MO, NC, NM, NY, and OH, (Ginns). It also occurs in Europe including the United Kingdom and in the Marshall Islands, (Martin, G.W.). There is a collection from BC by R. Bandoni at the University of British Columbia, and there are collections there also from CA by K. Wells, PA, IA, Norway, and Sweden.
