Presented at the Book & Paper Group Session, AIC 28th Annual Meeting, June 8-13, 2000, Philadelphia, Pennsylvania. Received for publication Fall 2000.

Abstract

Iron chests containing eighteenth- and nineteenth-century documents stored in a cellar of the R. C. Tilghman and E. Lloyd estate, Wye House, Easton, Maryland, were periodically submerged in water during seasonal floods over a period of eighty years before being found and re-opened. The documents stored in the chests were compacted into brick-shaped forms as a result of biological deterioration by fungi. The fungi, which produced vibrant pigmentation and fruiting structures, suggested a number of species rarely seen on the paper-based collections. Isolation and microscopic examination revealed four species representing members in the genus Chaetomium (Ascomycetina, Sordariales). These cellulytic fungi are tentatively identified as C. barilochense, C. brasliense, C. cymbiforme, and C. globosum. In addition to these, several conidiophores bearing conidia belonging to the genus Penicillium and the genus Aspergillus were also noted.

A full test report of this research appears in the reference cited below.
