green cap, unequal forked gills, and white, solid, almost smooth 

 stem. The former is of a highly poisonous nature, while 

 the latter, on the authority of Berkeley and Mrs Hussey, is 

 one of the edible species. Among the Auricularini we got Auricula 

 refiesa, now classed among the Polypori, and called Polyporus 

 versicolor, with a buff, yellow, or brown, smooth hymenium, and 

 reflexed zoned pileus, exceedingly common on dead trunks and 

 branches of trees throughout the whole year. Three other Poly- 

 pori or Sap-balls were collected — one a tolerably large specimen of 

 Polyporus squamosus, the largest species of our British Fungi. It 

 was detached from its habitat, but was too moist and decayed to 

 be carried away. It is known by its scaly fleshy pileus and sub- 

 lateral stem, and grows on stumps of decaying trees, chiefly those 

 of the Ash. The other species were Polyporus ulmarius and P. 

 vulgaris. What I called a Clavaria — the Clavaria hypoxylon of 

 Withering — is now grouped among the Ascomycetes, and called 

 Xylaria hypoxylon, Sioio. The hymenium is branched like the 

 horns of a Eeindeer, downy at the base, and black and white to- 

 wards the apex. The only Puff-ball collected was found by a lady, 

 and was a young plant of Lycoperdon verrucosum, with a warty 

 yellowish-brown peridium, and when full grown has a large 

 lacunose stem, thickened at the base, the peridium bursting at the 

 apex. Among Pezizee three species were found — Peziza virginea, 

 with a longish stipes and hemispherical subpatulate pileus ; P. 

 hirsuta, with a sessile sub -hemispherical cupule, an inflexed 

 margin, and vermilion-coloured inside ; and P. aurantia, with 

 cupule nearly sessile, irregular, oblique, orange, whitish externally, 

 and somewhat pruinose. We collected altogether about twenty- 

 five different species ; and had the season been more propitious to 

 the growth of these plants, I have no doubt that double that num- 

 ber would have been got in a locality so favourable to fungoid 

 growth. A week or two after our excursion, our fellow-member, 

 Mr James Monteith, went over the same ground, and sent me a 

 small box containing a dozen species collected by himself, seven 

 of which were not found on the day of the excursion. These 

 were — Agaricus fimiputris, A. velutipes, A. umbelliferus, and A. 

 varius ; Dgedalea quercina, Peziza tuba, and Nectria cinnabarina.
