272 FLORA OF TASMANIA. [Fungi, by M. J. Berkeley. 
Gen. LXI. POLYACTIS, ZA. 
Fioeei decolorantes, subfusci, rami versus apicem cymosi l. paniculati. Spore simplices. - 
Brownish Moulds, at first white, irregularly branched, with the ramuli mostly near the apex, and forming little 
cymes or panicles, but not vertieillate. (Name from zoue, many, and axrıs, a ray.) , 
1. Polyactis vulgaris (Lk. Obs. i. p. 14. f. 22). 
Has. On dead twigs, Archer. 
The few perfect individuals that I have seen are but slightly divided above, but the plant seems a mere form 
of the common P. vulgaris. The spores are slightly obovate, and about ¿2,7 inch long. 
Gen. LXII. RHINOTRICHUM, Corda. 
Flocci sursum incrassati, spiculiferi, spiculis sporiferis. Spore subglobosz. 
Distinguished from Botrytis by the swollen tips of the threads, which are studded with the spores. (Name 
from fum, a file.) 
1. Rhinotrichum microsporum (Berk); filis agglutinatis, clavulas subcylindricas efformantibus, 
apicibus cylindrico-clavatis, sporis globosis minutis. 
Has. On soil, Archer. 
White. Mycelium at first creeping, then agglutinated into little fascicles, so as to form short Isariseform clubs, 
but frequently barren; ultimate flocci cylindrico-clavate, obtuse, studded with very minute spicules, each of which 
bears a globose spore «gl inch in diameter.—This has the habit of an Isaria, and is moreover distinguished by its 
minute spores, 
Gen. LXIII. MORCHELLA, Dill. 
Receptaculum clavatum 1. pileatum. Hymenium costis elevatis lacunosum. Asci fixi. 
Morels occur in many parts of the world, and the common species is collected in the northern Himalayas, for 
food, as it is in Europe. I have seen but a single immature Tasmanian specimen. (Name Latinized from the 
German, Morchel.) 
1, Morchella esculenta, 8 conica (Fr. Syst, Myc. ii. p. 7). 
Has. On the ground, Archer. 
Gen. LXIV. HELVELLA, Z. 
Receptaculum pileatum, centro suffultum, deflexum, Hymenium leve, superum. Asci fixi. 
Distinguished at once from Morels by their lobed, even receptacle. Some of the species are esculent, as is 
probably the Tasmanian form. (Name applied to some Fungus or esculent vegetable by Cicero.) 
l. Helvella monachella (Fr. Syst. Mye. ii. p. 18). 
Has. In the valley on the north side of Cuming's Head, about halfway up, Nov. 1855, Archer. 
This is rather larger than the European form, but differs in no other respect. The pileus is dark-brown, lobed, 
deflexed, and adnate; the stem pale rufous, and smooth. 
Gen. LXV. LEOTIA, Hil. 
Receptaculum pileatum, orbiculare, margine revolutum, supra margineque fructiferum. Hymenium 
leve. Asei fixi.
