Diagnosis Tuber cryptobrumale morphologically resembles T. brumale, but differs in the size of the largest peridial cells (ASPC) and the average size of warts (Warts). ASPC of T. cryptobrumale is larger, 24.0 ± 4.98 μm (in the range of 16.6–38.73 μm) [vs. 15.65 ± 2.62 μm (10.93–23.4)]; Warts of T. cryptobrumale are smaller 1.3 ± 0.3 mm (0.9–2.0 mm) [vs. 1.8 ± 0.4 mm (0.9–3.3 mm)]. In addition, the ratios of threeand five-spored asci (R3 and R5, respectively) are different in the two species (31.4 ± 7.7 and 13.2 ± 6.8% in T. cryptobrumale vs. 23.7 ± 9.3 and 22.6% ± 11.1% in T. brumale, respectively). In addition, the two species differ in some unique fixed alleles on LSU and ITS loci, based on the alignments of loci deposited in TreeBASE (S18611). T. cryptobrumale’s unique fixed alleles are: ITS positions: 11(C), 18(T), 38(T), 39(C), 41(A), 44(C), 106(A), 111(T), 115(A), 120(G), 121(A), 123(T), 149(C), 158(G), 163(C), 176(T), 196(T), 201(A), 205(C), 208(A), 213(A), 216(G), 229(T), 242(T), 251(G), 258(G), 263(G), 266(T), 269(T), 275(G), 283(A), 285(C), 286(T), 290(G), 291(A), 296(gap), 297(C), 309(C), 317(G), 326(C), 329(T), 338(G), 340(C), 341(A), 346(T), 350(G), 351(T), 364(C), 420(C), 435(C), 444(C), 470(T), 637(C), 666(C), 680(A), 688(gap), 689(gap), 690(gap), 693(G), 694(A), 701(C), 705(A), 712(C), 713(G), 718(G), 727(T), 728(G), 732(A), 748(G), 779(A), 793(C), 794(C), 802(G), 804(T); LSU positions: 971(C), 972(T), 975(G), 1026(G), 1042(C), 1084(A), 1105(T), 1300(C), 1362(G), 1368(G), 1405(C), 1407(C), 1415(C), 1433(T).
