A NEW GENUS OF DISOOMYCETES.

new fungus seems to present. There is no doubt whatever that 
the hymenium is entirely enclosed, although both figures and speci- 
mens exhibit ruptured individuals in which the hymenium is laid 
bare ; but if we consider that in a perrcctly closed specimen the 
hymenium was fully matured, there is no reason to conclude that a 
wholly enclosed hymenium is not its normal condition. Perhaps 
Sphcerosoma comes nearest to Berggrenia , except that it has a 
thicker and firmer periderm, and is moreover hypogaeous. This 
affinity is sufficient to prove that it is not impossible for a plant of 
such a structure to be a Discomycete, and Tulasne considered 
Sphcerosoma to be a Discomycete although evidently so very 
closely related to Genea. Indeed, in my opinion Sphcerosoma is 
further removed from the Discomycetes in the direction of the 
Tuberacei than Berggrenia from some species of Peziza. 
There is a great similarity in the character of the fruit, and in 
the fleshy stroma, as to texture, &c., between Cyttaria and Berg - 
grenia ; in fact, the latter resembles the former, inverted, and the 
areolae suppressed. The hymenium is confined in some Cyttarice 
to a few nearly closed cells, and although the relationship is by no 
means close in any direction, I am inclined to place Berggrenia in 
the Bulgariacei, nearest perhaps to Cyttaria. The discovery here- 
after of intermediate links may render the affinities clearer than at 
present they seem to be ; under any circumstances the new genus has 
a higher interest than its mere position in any system of classifica- 
tion. — From the il Gardeners ’ Chronicle ,” Oct . 25, 1879, p. 533. 
AGARIC WITH GREEN SPORES. 
We have lately received from Mr. Morgan, of Ohio, U.S., a 
dried specimen of an Agaric, with all the external features of a 
large Lepiota , with a pileus nine inches in diameter, which has 
spores when first thrown down of a bright green colour, but upon 
drying these become of a duller verdegris green. This fungus has 
been named Agaricus Mo?gani, Peck, and is interesting as being 
unique in the colour of the spores. It is not an accidental circum- 
stance which has affected a single specimen, but one which is 
characteristic of the species. The individual spores, in the dried 
state, exhibit no colour when the light is thiown through them on 
the stage of the microscope. Probably this may not be the case 
with fresh spores. At any rate, the circumstance is worthy of 
being recorded.
