 be Byssus septica of Linnæus. Dr. Withering traces it, in his opinion, to fig. 3. of this plate. We, however, have no asslurance of the latter having been deteiled with pores, or other frutification, like this white one, which has been found in great abundance, and was brought me from Oxford by my good friend Dr. Williams. Its fibres are eafily decomposed. The figure represents it in some degree compresed.

THIS is a Poria of some authors, and is not uncommon under wooden window-fills or copings over the little brick, walls in hot-housfes, extending to a foot or more in length. I do not know that it has been found with a pileus. The pores resemble those of B. versicolor, being mostly round and white, sometimes lengthened out. The substance is nearly the same, being white cottony fibres closely compressed. B. versicolor is occasionally very sportive, and destitute of a pileus.

I WAS favoured with specimeris of this Boletus by D. E. Davey, Efq. of the Grove, Yoxford, in Suffolk. They grew on his wine-cellar door. The button-like form, with an umbilical root, like a fhank, gives this species a remarkable appearance. The pores in the centre are irregular, small, and shallow; the substance some what cottony, and closer than the dry rot. Boletus lacrymans. I cannot help mentioning here a large flat specimen of Boletus lacrymans, kindly communicated to me by the Earl of Dartmouth, about nine inches in diameter, the pores irregular in the outward circle, the centre composed of small, irregular, somewhat botroid protuberances.

THIS may be often found fpreading, in irregular patches, on bits of stick, &c. in damp places. The pores, when any, are somewhat central. The substance rather resembles fig. 1. of this plate, but is more compressed.
