Mabel Rayner

Mabel Rayner Mabel Mary Cheveley Rayner (c. 1890-1948) was an English botanist, mycologist and author, or co-author, of several books. Quotes As an important member of the moorland flora of Northern Europe, Calluna Calluna vulgaris is commonly associated with soils of a definite type, especially when it occurs as the dominant or sub-dominant species of moorland associations. As such, it is especially characterists of dry heath soils, deficient in Lime (material) lime and often Soil acidification acid in reaction.

Of these last, the scarlet Fly Agaric (Amanita muscaria) ... with a nearly related species, the Death Cap or Death's Angel fungus (Amanita phalloides) ... with a pale greenish-yellow Pileus (mycology) cap, common and abundant species about pine and birch trees and in woodlands formed by them, are two of the most notorious. The toadstools of both these species, especially those of the latter, contain virulent poisons and if cooked and eaten in the rest condition, are among the most deadly and dangerous poisons known; the Panther Agaric, Amanita pantherina, a toadstool with a brown spotted cap, is also common in such woodlands and also poisonous. It is interesting to note that the fleshy caps of these poisonous toadstools are eaten with impunity by slugs.

Observations by Pasteur in 1860 and 1862, by Carl Nägeli Nägeli in 1879 and 1883, and by Johannes Reinke Reinke in 1883 all showed the former could use a great variety of carbon compounds as food materials. Mycorrhiza: An Account of Non-pathogenic Infection by Fungi in Vascular Plants and Bryophytes Issue 15 of New Phytologist reprint Wheldon & Wesley, Ltd 1927 https://books.google.com/books/about/Mycorrhiza.html?id=mcA7cSipX28C&pg=PA8 8 (246 pages) A fresh attempt to survey the whole field and correlate the problems of nutrition presented by mycorrhiza plants with those in parasites and insectivorous plants was made by Christian Ernst Stahl Stahl at the opening of the new century (Stahl, 1900). This paper, the most comprehensive study of mycorrhiza from the biological point of view since the publication of Albert Bernhard Frank Frank's theory of symbiosis in trees, has been freely quoted in the text-books and is probably one of the best-known contributions to the literature of the subject. Two aspects of Stahl's work demand attention: firstly, the new hypothesis put forward by him to explain the distribution of fungus infection in vascular plants and its beneficial effect upon the hosts, and secondly, the character of the experimental evidence offered in support of his opinions. pp. 51–52 Quotes about Mabel Rayner In Trees and Toadstools, Rayner has given us an account, written in clear language understandable to the layman interested in science, of the symbiotic relationship which has been found to prevail between the mycelium of many of the higher fungi and forest trees. ... the story of Albert Bernhard Frank Frank's epochal discoveries, originally initiated as a project to increase the supply of truffles but resulting in the real opening of research on the important field of forest tree root and fungus association, is well told in simple language.
