Lopadostoma, Oligostoma, and some Rosellinia specimens from the herbarium of the Swiss Federal Institute of Technology (ZT): the value of early fieldwork and the importance of keeping fungal collections

Abstract

BackgroundMorphology, hosts, and collecting sites of fungi assessed from herbarium material of special interest deserve to be brought to the attention of mycologists.ResultsSpecimens of Lopadostoma and Oligostoma deposited at ZT are briefly described and listed to expand the knowledge about their distribution. Three yet unmentioned Rosellinia collections are reported. One could be identified as R. mastoidiformis, a second as R. neblina; both are known only from the type collections. The third one seems to be a yet undescribed taxon and is formally described as R. schueppii.ConclusionsThese observations emphasize the importance of keeping fungal collections and highlight the importance of field work and contributions by early mycologists.
