s an immense gain to the student when some vigorous 
worksite who knows how to attack epeobism and solve it, sets him- 
self to clear up the puzzles and sieoutitio of his subject. There 
are many such obscurities in Fun nent Mr. G. J. Atkinson 
has rendered this service in demonstrating the true life- history of 
Hypocrea alutacea. In this genus of Pyrenomycetes the usual 
mode of growth is a flat or cushion-like stroma, in which the peri- 
thecia are embedded. In the case of the upright- stalked species, 
alutacea, it was taken for saree that the main body of the plant 
elonged to some other fungus, Clavaria or Spathularia, on Which 
the Hypocrea seemingly spread a parasitic stroma.

Mr. Atkinson has supplied the proof hitherto wanting, by growing 
the fungus, an upright-stalked stroma, from spore to fruit on 
artificial media. He revives for it an old generic La and it now 
stands Podostroma alutacea. The paper originally appeared in the 
Botanical Gazette for December, 1905. In ear paper, reprinted 
om the Journal of Mycology for the same year, Mr. Atkinson

Jonann & Ernest Fettcen have Pes a preliminary study 
of a projected Fungus-Flora of the Duchy of Luxembourg, in 
which is presented a long and jumbled “list of species that follow 
sind other without any apparent order. Many new species are 
diagnosis appended; in another, ** Hyphomycet,” with only the 
habitat given. Doubtless the complete work will fill up the blanks, 
and give us a system easier to follow; but the present instalment 
is by no means a satisfactory production.
