Abstract

Mattirolomyces mexicanus Kovács, Trappe & Alsheikh is recorded for the ﬁrst time from the Yucatan Peninsula, Mexico, based on morphological and molecular data. This species is characterized by the whitish membranous peridium with inﬂate hyphae over 100 µm in diameter, pale gleba, subreticulat-ed ascospores of 15–21 µm, and the putative association with Fabaceae species. This is ﬁrst record of a sequestrate Ascomycota from the Yucatan Peninsula and the second record of the species worldwide. A description, photographs, and a molecular analysis of two DNA markers (ITS and LSU) are presented.
