Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1914 edition. Excerpt: ...than the outer and the hyphae composing it are not so closely matted together, though they are somewhat darker and more closely interwoven than are the hyphae of the context. Both layers of the rind and also the context are made up of hyphae 4 to 8p. in diameter. The structure of the hymenium is the same in every detail as that of Suillellus Eastwoodeae, Form A, previously described. The surface of the stipe is protected by a rind 20 to 30; in thickness, consisting of an almost solid tissue formed of very densely compacted dark-brown hyphae. The hyphae of the context lie nearly parallel to each other and to the long axis of the stipe. These hyphae, unlike those of most of the other plants I have investigated, are rather dark in color. The hyphae of the context increase from 4p. in diameter near the rind to as much as 12 to 16; at the center of the stipe. The hyphae also become lighter in color as the center of the stipe is approached. ROSTKOVITES P. Karst This is a genus distinguished from Ceriomyces by the presence of granular dots on the stipe and in this connection it may be well to repeat that in Ceriomyces communis, Form B, structures are found on the stipe which resemble the "glands" found in Rostkovites rather closely. This fact would seem to indicate that the presence or absence of glandular dots is merely a matter of their relative size and abundance, rather than of their actual presence or absence. Certain species of other genera are described as glandular dotted but these genera are all distinguished from Rostkovltes by the presence of an annulus. Moreover, we shall see when we consider Boletus luteus that in this" species at least, which is described as possessing glandular dots on the stipe, these...show more
