Fungi, by M. J. Berkeley.) FLORA OF TASMANIA. 271 
Gen. LVII. PILACRE, Fr. 
Peridium capitatam, supra membranaceum, tenerrimum, fatiscens. Spore subglobose, in strato su- 
pero peripherico coacervate. 
Small Fungi, with the habit of Onygena, but allied to the Moulds. (Name from mos, a hat, and axpov, the 
top of anything.) 
1. Pilacre divisa (Berk. in Fl. N. Zeal. p. 197). 
Has. On dead wood, Archer. 
The specimens are imperfect and undivided, but they appear to belong to the same species with those from 
New Zealand. 
Gen. LVIII. ISARIA, Hill. 
Receptaculum elongatum, floccosum, floccis sporiferis rectis tectum. Spore nude. 
Isarice are essentially compound Sporotricha, and, like them, are for the most part mere conditions of higher 
Fungi. Some however are autonomous. (Name from wos, egual ; from the equal height of the individual plants 
of the original species.) 
1. Isaria radians (Berk.); cervino-grisea, orbicularis, ramosa, undique floccis verticillatis vel sub- 
dichotomis vestita, sporis ellipticis minimis. 
Has. On bark, Archer. 
Forming patches 2-1 inch broad. Receptacle branched, radiating, composed of threads, the free portions of 
which are verticillate or subdichotomous, each branchlet being terminated by an elliptic spore 257 inch long.— 
This species resembles Jsaria umbrina, Pers., but the decidedly branched receptacle and radiating patches easily dis- 
tinguish it. It is not accompanied by any Spheria, but whether autonomous or not I am unable to say. 
Gen. LIX. TRICHODERMA, Pers. 
Peridium indeterminatum, e floccis ramosis septatis contextum, demum in medio evanescens. Spore 
minute, siccze, in disco conglobate. 
The species are probably not autonomous, and resemble collapsed patches of Mould. (Name from Dout, a hair, 
and depya, a skin.) 
1. Trichoderma viride (Pers. Syn. p. 230). 
Has. On dead bark, Archer. 
Gen. LX. VERTICILLIUM, Nees. 
Flocci ramosi, ramis verticillatis apice monospermis. pore simplices. 
Little Moulds, known by their distinctly whorled branches. Of exotic species very little is known. (Name 
from verticillus, a whorl.) i 
1. Verticillium niveum (Berk.) ; candidum, ramosum, ramulis basi incrassatis breviusculis, sporis 
oblongis. 
Haz. On dead Agarics, Archer. 
Snow-white, delicate, branched. Whorls consisting of about three branchlets, which are acute above, and 
thickened below. Spores oblong, zdgg inch long.—Differs from V. agaricinum in its shorter branches, more deli- 
cate habit, and far smaller spores.
