404 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
in diameter, forming a pseudoparenchyma; gleba white, becom- 
ing Sayal brown in alcohol, cavities variable in size, polygonal; 
septa 40—60 y. thick, composed of pseudoparenchyma much as in 
the peridium; basidia clavate, 20 X 7 u, disappearing early; 
sterigmata 2 u long; spores globose, 12 » in diameter, reticulate, 
surrounded by a gelatinous sheath. 
In pine and fir forests. Italy. 
Specimens examined: 
Italy: Vallombrosa, О. Mattirolo, Nov. 23, 1899, cotype of 
Leucogaster fragrans (in Mattirolo Herb. and portion in Thaxter 
Herb.) ; О. Maítirolo, 1910 and undated specimen (in Lloyd Mus. 
unnumbered and 064); Nocciuolo sopra Vallombrosa, F. Cavara, 
type (preparation from Mattirolo in Thaxter Herb.). 
4. Leucogaster Bucholtzii Mattirolo, Malpighia 14: 267-208. 
1900; Saccardo & Sydow in Sace. Syll. Fung. 16: 249. 1902. 
Type: location unknown to us. 
Characters of L. Tozziana (Cav. & Sacc.) Matt. with aculeate, 
instead of reticulate, spores. 
In fir forests. Vallombrosa, Italy. Summer. 
There seems to be so little in the original description to separate 
this species from L. T'ozziana that we are inclined to regard it as 
a variety of this species, but reserve our decision until authentic 
material has been studied. It is possible that a careful com- 
parison of collections referable here would show all the variations 
between fructifications with reticulate spores and those with 
aculeate ones.
