Technical Abstract: During the past two years a project has been undertaken to study endophytic fungi associated with plants growing in El Eden Ecological Reserve, located in the State of Quintana Roo in the northeastern part of the Yucatan Peninsula of México. Asymptomatic, healthy leaves were collected, surface sterilized, sectioned in 0.5 mm square pieces and then plated on potato dextrose agar. Among the fungi recovered was an interesting isolate from leaves of Callicarpa sp. The isolate forms slow-growing, odorless colonies and does not form mitosporic or meiosporic structures. The mycelium is composed of hyaline, septate hyphae that frequently unite laterally to form groups of three or more hyphae. Colonies on V8 agar are flat and smooth, but on MEA they are raised and wrinkled. On both media the colonies are white, but on MEA a dark, brown to reddish-brown pigment forms in the agar. On the basis of sequence analysis of ITS data, this fungus belongs to the Ascomycota but does not align closely with any sequences currently in GenBank, suggesting that it represents an undescribed taxon.
