NOTES: Lister (1898b: 163) in his description of the new species wrote “On May 3rd, 1897, Mr. Saunders sent me a specimen of an unfamiliar Physarum gathered the day before at Chaud End, near Dunstable; and on our visit to the spot on May 6th we found it in considerable abundance on the damp straw.” With reference to the substrate he wrote “The habitat is on straw, stable manure, and dead leaves.”, and commented “Besides the gathering near Dunstable the species has been obtained at several stations within a radius of a few miles; it was generally found on straw, but one gathering by Mr. Crouch at Pulloxhill was on dead leaves in a dry ditch. On March 11th, 1898, we found it in vast abundance on stable manure round sea-kale pots in my garden at Lyme Regis, Dorset.”. The specimens are illustrated on Pl. 386, fig. 2.

In BM 5 boxes were located ( BM 1845 , BM 1700 , BM 1700 A, BM 1709 , BM 2078 ), four of them were labelled “Type specimen” and agree with the data of the publication, We designate as the lectotype BM 1845 which was collected by the Listers from the type locality of Chaul End, on 6 May.1897. It is in good condition and is representative of the species. This collection has 2 slides (L:B.M.30A) and (1), the latter having a reference to notebook XIV: 3. In notebook XIV: 1–5 comments and illustrations were found of the material collected by Saunders on “May 2. 97”, of that collected by the author on “May 6.97” from the same locality, and in notebook XVI: 64–67 the collection from Highcliff from “Mar. 11.1898” .

In K (http://apps.kew.org/herbtrack/results) there are two specimens [K 171256, England, 1893, on manure, Lister , and K 119823, England, 1898, on old straw, anon. (ex herb. G. Lister)], that could be part of a duplicate or a syntype .
