The current estimate of bryophyte specimens at the T. M. Sperry Herbarium (KSP) at Pittsburg State University is 7000, with at least 1000 backlogged, representing 25 countries. Exsiccate from various sources are among the backlog. Significant collections include those of the previous curator Stephen L. Timme. A small number of specimens (<300) databased on the main KSP database portal will be transferred here eventually. Most data initially were captured via OCR by MO with support from NSF.
