Doyle’s Delight, the Maya Mountains in Belize - yet another four new genera identified.

Continuing evaluation of the 30 or more new taxa discovered on the 2007 expedition to Doyle’s Delight in the Maya Mountains of Belize, has revealed four of these entities to be new genera of Basidiomycota, 3 agarics and 1 new genus of polypores. The morphological features for each of these taxa clearly indicate they cannot be placed into existing genera, and attempts to consign these organisms into a phylogenetic framework reveal that they do not fit within existing clades using nlsu (and ITS) sequences either. We propose the following new genera of Agaricomyetes, Nubicola, Pachytrama and Neotrogia, and the new polypore genus Aurantiopileus to accommodate these distinctive taxa from this cloud forest of the Maya Mountains. The salient morphological features will be illustrated and brief synopses and discussion for each of these new genera, including phylogenetic placement will be presented. We now know of 5 new genera from Doyle’s Delight, including the previously published Arthromyces (Lyophylleae, Agaricomycetes). We will discuss the reasons why this particular area in Central America is such a hotspot for discovery of novel macrofungi.
