226 THE ESSEX NATURALIST. turning blue. The Rev. Mr. Hemsted has sent it me several times from the neighbourhood of Newmarket, and I have found it on the Croydon road, and at Hainault forest. It seldom produces good specimens, and is frequently indistinct, as exhibited in Schaeffer's figures. The pores are small, and sometimes irregular. TAB. CCXXXIII. Clavaria phacorhiza. Dicks. fasc. 2. 25. [Typhula.] First found in a garden at Walthamstow. I have gathered it since in Kensington-gardens. The plant is a slender simple undulating thread, terminating rather bluntly at the apex. The substance at the base somewhat resembles a bean or seed splitting to protrude a young plant. Sometimes the head is straighter, and resembles a bodkin or netting-needle. TAB. CCL. Boletus rubeolarius. Bull. 100 and 490. fig. I. With. ed. 3. v. 4. 315. --------- luridus. Schaeff. 117. [Boletus luridus.] Not very rare. I have found it at Homsey-wood, and at Hainault forest, Essex. My friend, the Rev. Mr. Charles Abbot, sent me a specimen from Bedfordshire. The fine carmine, cinnabar, or vermillion-coloured powder or seed, is often so copiously shed as to stain everything that touches it, and is so thick under the pores as almost to obscure them. TAB. CCLXXVIII. Clavaria coralloides. Huds. 640. With. ed. 3. 367. A Very common fungus. It is equally variable in form and colour, but mostly white. The substance is brittle, dense, nearly solid. The taste is agreeable, resembling that of the common Mushroom, Agaricus campestris. Found in great plenty in the shrubbery at Wanstead House, Essex, by Mr. B. M. Forster. TAB. CCXCVII. Sphaeria floriformis. [? Anthostoma decipiens.] I Found this curious Sphaeria on a hornbeam on Hainault forest. It is most readily distinguished by the plaited and flower-like appearance at the mouth. TAB. CCCIV. Agaricus Georgii. Linn. With. v. 4. 226. [Psalliota arvensis.] This plant differs very little from the common Mushroom,
