SPECIES, AUTHORITY P. agglomeratus (Kidston & Lang) Kalgutkar & Jansonius 2000
LOCATION Muir of Rhynie, Aberdeenshire, Scotland.
ORIG DESCRIPTION* Fine hyphae attaining a diameter of 5 µm, with terminal or intercalary dilatations [sic] giving rise to spherical thin-walled resting-spores 40-50 µm in diameter, that often occur in irregular masses.

Occurs in the tissues of all the vascular plants of the Rhynie deposit, but especially in stems of Rhynia gwynnevaughanii and in the matrix in connection with them.
COMMENTS* The generic name Palaeomyces [quo vide] is employed here as a "useful and comprehensive designation" under which to place fossil fungi, of the precise systematic position of which there is insufficient evidence. It is, therefore, not further defined, but the fungi from the Rhynie deposit that are described as species of this genus agree on their usually aseptate mycelium bearing spherical or oval vesicles or resting-spores.

In the case of each species a particular slide in the Kidston collection is cited that can be regarded as the type specimen. Most of the species occur more or less frequently in preparations of the Rhynie chert.
