From: Further evidence of Ceratobasidium D.P. Rogers (Basidiomycota) serving as the ubiquitous fungal associate of Platanthera leucophaea (Orchidaceae) in the North American tallgrass prairie

Fig. 2

Locations in the Midwestern United States where Ceratobasidium fungi were isolated from roots and/or protocorms of Platanthera leucophaea as of 2017. The shaded areas reflect the orchid’s historic distribution (Bowles 1983). Solid dots indicate locations where Ceratobasidium (=Ceratorhiza) was recovered from P. leucophaea prior to the present study. The two solid dots from lower region of Illinois (Christian and Macoupin Co.) were locations where protocorms of P. leucophaea were acquired from seed packets (see Zettler and Piskin 2011). Pink dots with numbers represent sites where Ceratobasidium was acquired from P. leucophaea in the present study: 1 = Lake Co., IL; 2 = Dupage Co., IL; 3 = Kenosha Co., WI; 4 = Tuscola Co., MI; 5 = McHenry Co., IL; 6 = Jackson Co., IA; 7 = Cook Co., IL; 8 = Will Co., IL; 9 = Kane Co., IL; 10 = Lee Co., IL. Pink dots lacking a number reflect tallgrass prairie sites where Ceratobasidium was isolated from orchids other than P. leucophaea (i.e., Platanthera lacera, P. peramoena, Spiranthes magnicamporum, S. vernalis)
