HdV-262Type: HdV-262

Category: Fungi

Taxonomical identification: Arnium imitans-type / Arnium spp.

First publication: van Geel, B., Buurman, J., Brinkkemper, O., Schelvis, J., Aptroot, A,. van Reenen, G. and Hakbijl, T. (2003) Environmental reconstruction of a Roman Period settlement site in Uitgeest (The Netherlands), with special reference to coprophilous fungi. Journal of Archaeological Science 30, 873–883

Other publication/s: van Geel, B. and Aptroot, A. (2006) Fossil ascomycetes in Quaternary deposits. Nova Hedwigia 82, 313–329

Description: Ascospores 1-septate (with an indistinct, thin median septum), 38–41 x 18–21 μm in size, ellipsoidal, with a ca. 1 μm wide, slightly protruding pore at both ends. They seem to belong to a member of the Sordariales, most probably to the genus Arnium, which is one of the few genera with ascospores with two germ pores. The genus has few species with septate ascospores, e.g. A. imitans, but the ascospore dimensions are too large.

(Sub-) Fossil occurence: In soil samples from a Roman Period settlement site in the Netherlands.

Co-occurence: No information

Modern occurence: No information

Palaeoenvironmental indication: In combination with other botanical and zoological data, the fungal record pointed to a high density of domesticated herbivores.
