<div>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif;color:black">Macrofungi – the subset of fungi distinguished by having macroscopic sporocarps – play diverse ecological roles in wild ecosystems, including substrate decomposition, enhancement
of soil fertility, and facilitation of rhizosphere dynamics as root symbionts. Recent observations facilitated by current sequencing methods reveal that some macrofungi occur in an endophytic phase within plant tissues. Thus, to characterize macrofungal diversity
it is beneficial to combine traditional methods such as collections of sporocarps and reviews of fungal herbarium specimens with evaluation of plant tissues for evidence of endophytic macrofungi. We characterized macrofungal diversity in a biodiversity hotspot
in southern Arizona: the Santa Rita Mountains and the adjacent grasslands and oak woodlands of the Santa Rita Experimental Range. The goal of my work was to provide a first inventory of macrofungi in the Santa Rita region, synthesizing data streams that include
over 1000 community science records collected via iNaturalist, a historic collection of herbarium specimens collected over the last century from the area, current field inventories, and sequencing of endophytes from plants to understand the contributions of
endophytes to macrofungal biodiversity in this area. Records of sporocarp collection from over a century, coupled with new collections, iNaturalist observations, and molecular analyses of endophyte communities, revealed more than 300 species of macrofungi
for the Santa Rita Mountains and Santa Rita Experimental Range. New collections for the 2024 monsoon season coupled with iNaturalist records added over 40 species to the known records (>10%). We detected macrofungi as cryptic endophytes in both burned and
unburned grasslands, oak woodlands and conifer forests, but the contribution to the macrofungal inventory of the region was limited relative to the inputs of community scientists/observers and Herbarium collections. Together these data show the importance
of community scientists and observers, natural history collections, and new collections in detecting and characterizing macrofungal biodiversity.</span><o:p></o:p></p>
