*236. Arthrinium Puccinioides, Kz., Myc. heft 2. p. 103. 

 Torula Eriophori, Berk. Eng. Fl. vol. v. part 2. p. 309. An 

 inspection of my plant with higher magnifying powers than I 

 possessed at the time of the publication of the concluding vo- 

 lume of the f English Flora/ shows that it is certainly that cited 

 above, and exactly agreeing with Desmazieres' published spe- 

 cimens. In neither are the sporidia very distinctly angular, 

 and by no means in so high a degree as Corda represents 

 them. They are nearly of the shape of two cones placed base 

 to base, which gives them an angular outline. I find them as 

 Corda does, attached in whorls, at the dissepiments. 



237. Aspergillus aurantiacus, n. s. Ncematogonum auran- 

 tiacum, Desm. ! Ann. d. Sc. Nat. n. s. vol. ii. tab. 2. fig. 1. On 

 elm bark. Apethorpe, Norths. Having found this very cu- 

 rious production in every stage of growth, I am enabled to state 

 that it is certainly a true Aspergillus, very nearly allied to A. 

 aureus. When in perfection the threads are simple, and the 

 sporidia attached in moniliform rows to a larger one at their 

 base. It has, however, a great tendency to become proliferous, 

 especially when it has been beaten down by the weather ; in 

 which case new threads proceed from the swollen receptacles, 

 forming a more or less intricate mass. In one instance I saw 

 a few short spicules on one of the receptacles, marking, I sup- 

 pose, the situation of the chains of sporidia.

*238. Botrytis lateritia, Fr. Syst. Myc. vol. hi. p. 402. In 

 an early stage of growth the sporidia are contained in a large 

 globose sporangium ; it accords therefore with Stachylidium 

 rather than Botrytis. Botrytis allochroa is probably the same 

 thing, as is also apparently Acrostalagmus parasitans, Corda. 



239. Botrytis destructor, n. s. Grisea, sparso-effusa ; floccis 

 vix septatis erectis, ramis alternis, ultimis furcatis, uncinatis 

 et divaricatis ; sporidiis obovatis basi valde attenuata. On the 

 leaves of various species of Allium. Spring. Very common 

 and destructive in some years, preventing the plants which are 

 attacked from coming to perfection. The individual threads 

 are distinct, but form large patches on the leaves, or even en- 

 tirely cover them. Flocci erect, not septate, branched alter- 

 nately ; ultimate ramuli forked and uncinate, or divaricate. 

 Sporidia seated on the tips of the ultimate ramuli. Nearly 

 allied to B. parasitica, of which there are many forms or al- 

 lied species, but distinguished easily from all by the peculiar 

 shape of the sporidia.

 spores. All more or less magnified.
