Lado, Carlos & Basanta, Diana Wrigley De, 2024, The type material in the David W. Mitchell myxomycete collection at the Royal Botanic Garden, Kew, Phytotaxa 649 (2), pp. 135-158 : 141-142

Badhamia crassipella K.D. Whitney & H.W. Keller, Mycologia 74(4):620 (1982)

Paratypus: USA. California, Chico, Lower Bidwell Park, on decayed plant debris, 4 Feb 1967, D.T. Kowalski 5229, DWM 3939 [one box, K-M001435110], ( Fig. 2C ).

Notes. This collection of Kowalski, currently at BRIT 526440, with a duplicate at CHSC 018571 and CHSC 057606, appears among the “Collections examined” by Whitney & Keller (1982), when they described the new species, so the Mitchell material is a paratype. The holotype K.D. Whitney 800 was deposited at BPI, but only BPI 743315 (K.D. Whitney 792), was found in their database. According to Whitney & Keller (1982: 622) paratypes were distributed to the following Institutions IMI, NY, K, UC, and individuals D.W. Mitchell and N.E. Nannenga-Bremekamp, and numerous specimens were retained in the author’s and D. T. Kowalski private collections, currently at CHSC and BRIT.

* Badhamia delicatula D.W. Mitch. & Nann. -Bremek., Proc. Kon. Ned. Akad. Wetensch., C. 79(4):383 (1976)

Isotypus: FRANCE. Dompierre- aux-Bois, foret de la Montagne, 10 km N of St. Mihiel (Meuse), on decayed wood, 9 Apr 1975, leg. D.W. Mitchell, DWM 1891 [one box + one slide, K-M001435094], ( Fig. 2D ).

Notes. In K Fungarium two samples of DWM 1891 are preserved, the holotypus [K-M001434282] deposited when Mitchell & Nannenga-Bremekamp (1976) described the new species, and this duplicate (K-M001435094) that Mitchell preserved in his private collection. Another isotype was also preserved in the collection of Nannenga-Bremekamp 9316, now deposited at BR (BR5020003261609 and BR5020061439385).
