FLOEA OF NEW ZEALAND.

A very curious genus, allied to Erysiphe, but with a Dematioid habit. The species occur in warm climates, and 

 are furnished with variously formed fulcra, as in Erysiphe. ' (Name of doubtful origin.) 



1. Meliola amphitricha, Pr. El. v. 2. p. 109. Bornet in Ann. des 8c. 1851, v. 16. p. 267. 

 Hab. On living leaves of various plants, Colenso. 



Gen. LXXIII. CHZETOMIUM, Kze. 



Perithecium membranaceum, astomum, pilis opacis vestitum. Asci gelatinosi, cito evanidi. Sporidia 

 fusca. 



Distinguished principally from Sphceria by its brittle, membranaceous perithecia, and evanescent asci. (Name 

 from x alT Vi hah'') 



* Chffitomium amphitrichum, Corda, Ic. 

 Hab. On damp paper, Colenso. 



* Chastomium elatum, Kze. Myc. Reft. t. 1. p. 15 (quoad nomen genericum), Ews. n. 184. 

 Hab. On damp straw, Colenso. 



Gen. LXXIV. CAPNODIUM, Mont. 



Flocci nigerrimi, articulati, moniliformes, immixtis aliis sequalibus, sporangia elongata quandoque ra- 

 mosa apice ssepe fimbriato-investientes. Asci in quibusdam perfecti, in aliis spora tantum (spermatia ut 

 videtur) adsunt. 



A very curious genus, from its close connection with Antennaria, insomuch as to make it probable that it is 

 the more perfect form of that genus. The sporangia, which are much elongated, sometimes contain asci and spori- 

 dia, but sometimes produce merely minute spores ; but besides this, in certain stages of growth they present all the 

 characters of Antennaria ; at least, in the same specimen, some parts exhibit the characters of that genus, while 

 others have the structure of Capnodium. (Name from Karros, smoke.) 



1. Capnodium fibrosum, Berk.; crassum, compactum, sporangiis elongatis rigidis fasciculato-ramosis. 

 Hab. On bark, Colenso. 



Forming a rigid, bristly stratum \ of an inch thick. Sporangia very much crowded, sometimes making almost 

 a solid mass, fasciculato-ramose, very much elongated and very rigid. — The specimens are not in a very good state, 

 and I can therefore make only an imperfect description. The species, however, is very distinct. 



Gen. LXXV. ANTEXNAEIA, Li. 



Flocci nigerrimi, articulati, moniliformes, hie illic sporangia granulis vel plantula pusilla repleta 

 emittentes. 



The pests of plants, especially of those with persistent leaves, in all climates, but nowhere more abundant than 

 in New Zealand. A. scoriadea, which forms thicker masses than the other species, perfectly smothers the plants in 

 which it grows. (Named from the resemblance of the threads to the antenna of some insects.) 



1. Antennaria Robinsonii, Mont, in Hooi. Lond. J. Bot. v. %. p. 641. t. 24*. 



Hab. On leaves of Phormium, Middle Island, Lyall ; on Kymenophyllum, Colenso; and on many 

 other plants. 



It is almost impossible to say what is a species in this genus. Dr. Lyall's plant has quite the characters of 

 that of Dr. Montague, except that I find the moniliform thread occasionally rough, as in A. pannosa. The sporangia 

 too, instead of being filled with a mass of threads, are gorged with extremely minute granules. This is, however,
