 myces melanoxant/ius, Berk. Ann. N.II, xiii, p. 359. 



In oak or beech woods, often attached laterally to sticks, leaves, 

 &c., without any connection with the ground. Oct. 13owood 

 Park, Bristol, King's Clilife, and Devonshire. 



About the size of a horse bean, globose, but more or less compressed and 

 anf^ular, furnished with a distinct absorbent base ; externally black, clothed 

 with obtuse but not rigid warts, which are less manifest when the plant is 

 dry. Flesh of a dirty olive yellow with broad black veins, which consist of 

 a loose slightly branched tissue arising from hexagonal cells, the ends of the 

 threads of which become oblong-elliptic, distinct, pedicellate asci, contain- 

 ing S dark, globose, echinulate, but not reticulate sporidia. Smell in some 

 speciuions like that of some agaric, in others strong and nauseous. The peri- 

 dium is black in every stage of growth. — ul . J. B. Spores "OIS-'OIG m.m.

Subglobose, minutely warted, peridium brown, powdered with 

 lemon-coloured particles ; apex bright lemon-yellow, internally 

 yellowish ; interstices floccose, lemon-yellow, base rooting. — B.

In woods. Near Bristol and in Wiltshire and Devonshire. 



Very nearly allied to P. melanoxanthus , which is, however, black in every 

 stage of growth, and has but little odour, whereas this is densely powdered 

 with lemon coloured particles, and has a strong smell, like that of rotting 

 sea weed. The orifice is generally more expanded, and is of a fine deep 

 lemon yellow from the exposure of the interstices of the fructif;yiug veins, 

 and the peridium thin and brown frosted with yellow, when young of a uni- 

 form gamboge yellow. In P. melanoxanthus the veins are nearly black, with 

 yellowish interstices, and the peridium thick, far more coarsely warted, more 

 compressed, and irregular in form and always black. — M.J.B- 



22^0. Pachyphlceus conglomeratus. B. St" Br. " CoDglome- 



rate Pachyphlceus." 



Irregularly lobed and plicate, conglomerate, even ; peridium 

 rufous-brown, interstices of the lobes clothed with adpressed 

 silky, yellow fibres. — B. ^' Br. Ann. N.H. xviii. p. 80, TuL Hyj^. 

 p. 132. 



In woods. Oct. Near Bristol. 



About an inch in diamer, shortly stipitate, much lobed, and plicate as if 

 made up of a number of individuals, the lobes rounded, of a deep brown- 

 olive. Sometimes quite even, sometimes rather rough, but not the least 

 verrucose, interstices of the lobes clothed with adpressed silky, yellow fibres. 

 Asci clavate, irregular, containing eight globose, tuberculate sporidia. Spor- 

 idia larger than in the other species ("0192 m.m.), and differing in their ap- 

 pearance. — M. J. B.
