NOTES: In the description of this new species Lister (1894: 41) details habitat and collections examined. “On dead leaves, wood, etc.– Moffat (L:B.M.14); Philadelphia; (L:B.M.14); Ohio (L:B.M.14) and on the Moffat material comments “The specimen from Moffat, described in Journ, Bot., 1891, under the name P. Brawnianum de Bary, agrees with de Bary’s description of that species in the usually sessile form and brown lime-knots of the capillitium, but as the type consists of only a single gathering by A. Braun near Berlin, and is not represented in the Strassburg or British collections, no proof of identity has been obtained; the Moffat specimen is therefore placed under P. murinum , the sessile American forms of which it closely resembles”.

In BM there are four collections ( BM 371, BM 1203, BM 1204 and BM 3217) from Moffat and Ohio, and 3 slides

(2 dry mounts and 1 prepared slides) from these localities. Specimen ( BM 1204) is from Philadelphia. All are material in the original description. No notes were located.
