2-24 FUNGI. [Sclerotium, 



On carrots, parsneps, cabbages, &c., pitted for winter use, but also 

 on still living stems of herbaceous plants, as Helianthics tuberosus ; 

 not uncommon. — From 2 — 3 lines to 1 inch broad, 2 — 3 lines thick, at 

 first white and tomentose, gradually becoming smooth, though often 

 retaining some traces of downiness, and changing to brown and black, 

 rugose when old ; white within, consisting of branched filaments, which 

 towards their apices anastomose and form 4 — 5-sided reticulations, the 

 interstices of which are filled up with tiie black epidermis. I can- 

 not distinguish from this a Sclerotium, which grows on apples, though 

 more innate. The present species when young approaches very near to 

 Feriolci tomentosa, Fr., which occurs not only on Potatoes, but also 

 on stems of herbaceous j)lants. In like manner also the variety on 

 apples appears to approach very nearly when young to Periola fur-- 

 furacea, except that it is not black within. 



8. *S'. pijrinum, Fr. {fruit Sclerotium) ; rounded or oblong 

 sometimes confluent white at length brown or black, corneous 

 externally? within somewhat hollow and carnose. Fr, Syst, 

 Myc. V. 2. p, 258.— S. fructuum, Grev. FL Ed. p. 462.— .'*Sc. 

 varium, (SiS, Alb, S)- Sclnv. Consp, p, 75. — Sr, ustulatay Bull, 

 t. 420./ 2. 



On various fruits, as apples, pears, peaches, &c. Balmuto, Dr. 

 Greville. — " Plant 1 — 2 lines broad, corneous on the external surface 

 only ; within soft, juicy, and partly hollow, which in drying causes a 

 collapse of the plant, and somewhat of a tremelloid character." Grev, 

 I. c. See also Fr. EL 2. p. 44. 



9. S.Eiibi, Carm. (Bramble Sclerotium) ; rather thin, adnata, 

 apparently globoso-depressed from the inflation of the leaf 

 beneath, white, then brown, at length black punctato-rugose 

 white within. Carm, 3ISS, 



On bramble leaves. Appin, Captain Carmichacl. — This very sin- 

 gular and undoubted Sclerotium grows indifferently on the under and 

 upper side of bramble leaves, adnate, covered at first with the epidermis, 

 so that when on the under side, it is woolly with the pubescence of the 

 leaf. At first sight it much resembles a gall, the portion of the leaf on 

 which it vegetates being inflated, as in Erineum Jwjlandis, DC. 



10. S, bulldtumy DC. (Jbullate Sclerotium); orbicular or 

 ovate confluent convex granulated, flesh within whitish. Dec, 

 Mem, Mus. v, 2. t, 14. /. 5. Fr, Syst, Myc, v, 1. p. 259. 

 Grev. FL Ed, p. 462. 



On decaying gourds and cucumbers. Autunm. Foxhall, Captain 

 Waufjh. — 1 believe however that it is not uncommon. My specimens 

 are blackish within both when growing and dry. 



11. S. durum, Pers. (common black Sclerotium'); adnate 

 or shapeless depressed somewhat striate black dirty-white 

 within. Pers, Syn. p, \2i, Fr, Syst. Myc, v. 2. p, 259.
