334 FUNGI. XFachmcyhe* 



Lh Sp. 2. p. 109. Chev. Par. 1. p. 41. — Doratomyces Neesii, 

 Cord, in St. Deutsdu FL Fung. v. 2. t. 30. 



On wood, sticks, stems of herbaceous plants, rotting potatoes, &c. 

 Winter and Spring. Very common in Northamptonshire. Rev. M, 

 J. Berkeley. — Stem \ — 2 lines or more high, brownish-cinereous, truly 

 subulate or slightly incrassated above, often fasciculate ; occasionally 

 breaking up longitudinally into thejiocci of which it is composed ; the 

 upper half clouded with the minute elliptic sporidia, which gradually 

 fail away when the plant is placed in water, altogether unmixed with 

 flocci. My plant is altogether that of Nees von Esenbeck, and is 

 entirely destitute of filaments amongst the sporidia. I have examined 

 it at various times and in every stage of growth and could never detect 

 an}'. It does not then accord with the genus CephalotricJmm, and as 

 the original plant of Tode appears to have an inflated vesicular head, 

 and the woixl Doratojmjces, formed by Corda for a single species, does 

 not express the general character of the genus as now proposed, I 

 think it best to give it an entirely new name alluding to the heads 

 frosted over with the sporidia. I have foreborne quoting the figures 

 of Haller, Fl. Dan. and Sowerby, though some certainly belong to the 

 present fungus, as I know not clearly what Cephalotrichum Stemonitis 

 is, and I am unwilling to create any needless confusion. 



2. P. grisea J Berk, (grey roimd-headed Pach?ioci/he) ; densely 

 gregarious abbreviated, stem blackish, heads globose, sporidia 

 grey. 



On decaying stems of herbaceous plants. Apethorpe, Norths. Bev. 

 M. J. Berkeley.— Much, stouter that P. acicula, with which it agrees 

 much in habit ; stem dark, nearly black, composed of fibres not a line 

 high, head greyish at length dusky ; sporidia elliptic. 



3. P.ferruginea, Berk, (ferruginous Paclmocybe) ; stem shin- 

 ing ferruginous, mycelium floccose, head globose. — Mucor ferru- 

 gineus, Soiv.J t. 378. f. 10. — Aspergillus ferrugineus, LL Sp. 

 l.p.eS. Pers.3Iyc. Eur. I. p. SO. Fr. Syst. Mi/c. v.3. p. 387, 



On deal and various decaying substances. Sowerby. — Authentic 

 specimens from Sowerby's Herbarium, though not those figured, are 

 now before me, on deal bought for fire-wood, and though scarcely 

 agreeing as to habit with Persoon's species in the 3Iyc. Pur., their 

 plants are probably the same, as the form is altogether that oi' Aspej'- 

 gillus. The specimens before me are extremely short, scarcely visible 

 to the naked eye, furnished with a thin but decided mucedinous 

 mycelium ; stem capillary, shining, ferruginous, composed of many fila- 

 ments ; head globose or depressed. Sporidia elliptic. 



4. P. acicula, Berk, (lohite round-headed Pachnocyhe) ; gre- 

 garious stem white or pallid, head subglobose. 



On rotting stems of herbaceous plants. Apethorpe, Norths. Rev. 

 M. J. Berkeley. —Mycelium obsolete. Scarcely a line high, gregarious, 

 but rather scattered, pure white or with the slightest possible pallid 

 tinge on the stem. Stem splitting up into fibres ; receptacle subglobose, 

 covered with minute elliptic sporidia. It has much the habit of 

 Aspergillus candidus ; from which however it is known by the different 

 structure of the stem and the elliptic, not globose and raoniliform, 

 sporidia.
