DistributionWidespread throughout central Mexico (southern Jalisco to Querétato and Veracruz), south to southeastern and south-central Guatemala, to southern Honduras; 1870-3050 m; growing almost exclusively as an epiphyte on horizontal branches of mature Arbutus, cyprus, elm, juniper, pine, or oak trees, often in moss and organic litter. Occasionally the species is found on the ground in the woods, in rotting wood of fallen trees, or in moss, like its sister taxon S. clarum. Spooner et al. (1998) were unable to locate S. morelliforme at some previously documented localities that had been logged and reforested, and the range of this species may have been reduced by deforestation. The southernmost record of S. morelliforme, Molina & Molina 26100, was collected in Honduras in 1961, the only record for that country. Antonio Molina (EAP) kindly led Spooner and collaborators back to the exact spots where he originally collected it in small valleys off the main road from Tegucigalpa to Lapaterique. One of these was at a place called Las Tablas at 1600 m, at 14º03.95’N, 87º22.73’W, and the other at Quebrada Honda, at 1610 m, at 14º03’56”N, 87º24’44”W. The species was no longer present in this area and Spooner et al. (2004) could not find it in other nearby sites.
