XXXIII.—On Old Red Sandstone Plants showing Structure, from the Rhynie Chert Bed, Aberdeenshire. Part V. The Thallophyta occurring in the Peat-Bed; the Succession of the Plants throughout a Vertical Section of the Bed, and the Conditions of Accumulation and Preservation of the Deposit

Abstract

In this concluding part of the series of papers on the plants preserved in the Rhynie chert-band, various remains of lower plants that occur in the peat will be described, and some general questions concerning the accumulation and preservation of the deposit considered. The paper is divided naturally into the parts enumerated below. 1. An account will be given of a number of forms of Fungi which are met with in the decayed remains of the vascular plants, and also in the peaty matrix. The fungal remains are so generally distributed that they can be regarded as forming an integral part of the peat. In connection with them, the question as to whether there is evidence of a mycorrhizal relation between any of the Fungi and the Vascular Cryptogams will be considered.
