From Costa Rica in sect. Genuina, we describe as new <em>T. luteopallidum</em>, <em>T. cacumense</em>, and <em>T. talamancense</em>, and confirm the occurrence of <em>Tricholoma stans,</em> and from the United States describe as new <em>Tricholoma brunneoluteum. Tricholoma roseoacerbum</em> from sect. <em>Megatricholoma</em> is con-firmed for Costa Rica. Morphology as well as ITS sequences are employed to confirm the species’ identifications or circumscription of the new species.</p>}, number={2}, journal={Journal of the Botanical Research Institute of Texas}, author={Ovrebo, Clark L. and Halling, Roy E. and Hughes, Karen W. and Kuo, Michael}, year={2021}, month={Dec.}, pages={545–557} }
