278 FLORA OF TASMANIA. [Pungi, by M. J. Berkeley. 
1. Cordyceps Gunnii (Berk.).—Spheria Gunnii, Berk. in Hook. Lond. Journ. Bot. vi. p. 577. 
Has. On the pupa of some Hepialus, Gunn. 
The New Zealand species grows on the larva (not the pupa) of an insect of the same genus. Ergot occurs on 
Grasses in Tasmania, but it is uncertain to what species of Cordyceps it owes its origin. 
Gen. LXXVI. HYPOCREA, Fr. 
Stroma horizontale, carnosum vel subgelatinosum, interdum obsoletum, ut plurimum laetius coloratum. 
Perithecia tenera.  Sporidia plerumque indefinita. 
Hypocrea is to Cordyceps what Hypoxylon is to Xylaria, containing those species whose stroma is horizontal, 
and not essentially vertical. "Their bright colour at once distinguishes them, or, where that fails, the fleshy sub- 
stance. (Name from io, beneath, and peas, flesh.) f 
l. Hypocrea semiorbis (Berk.).—Sphæria semiorbis, Berk. in Hook. Lond. Journ. Bot. ii. p. 146. 
Has. On dead wood, Gunn. 
2. Hypocrea rufa (Fr. Summ. p. 383). 
Has. On dead wood, Archer, 5 
9. Hypocrea citrina (Fr. Summ. p. 386). 
Haz. On dead wood, J. D. H., Archer. 
4. Hypocrea tomentosa (Fr. MSS.). 
Has. On the hymenium of Polypori, Archer. 
Forming a white, delicate, tomentose stratum, without any very distinct stroma. 
Gen. LXXVII. NECTRIA, Fr. 
Peritheeia libera vel mycelio 1. stromati insidentia, tenera, leete colorata, verticalia. Sporidia ut plu- 
rimum octona, translucida. - 
Differing from the two foregoing genera in the free perithecia. (Name from vyxrpis, a swimmer ; in allusion 
to the fluxile contents of the perithecia.) 
l. Nectria agaricicola (Berk.); cinnabarina, peritheciis ovatis acutis lævibus, ascis cirrhiformibus 
longissimis, sporidiis filiformibus. (Tas. CLXXXIII. Fig. 14.) 
Has. On dead Agarics, Archer. 
Gregarious on the stems, gills, etc., of Agarics. Perithecia ovate, acute, scarlet; walls vesiculo-fibrous. Asci 
extremely long.  Sporidia very slender, filiform.—A splendid and highly curious species. —Prare CLXXXIII. 
Fig. 14; a, group of perithecia; 5, asci; c, part of ascus and sporidia :—magnifed. 
2. Nectaria tephrothele (Berk.) ; peritheciis sparsis coccineis ovatis, ostiolo papilleeformi obscuro, 
sporidiis subfusiformibus guadri-nucleatis. 
Haz. Parasitic on some species of Hypoaylon, Archer. 
Bright-scarlet, studding the surface of the brown Hypozylon. Perithecia scarlet, ovate; ostiolum papilleeform, 
cinereous. Asci thicker in the middle. Sporidia biseriate, 75155 inch long, at length containing four endochromes 
—Resembling N. epispheria, but differing in several particulars. 
3. Nectria coccinea (Fr. Summ. p- 388). 
Has. On fallen branches, Archer.
