Il. Massarta. 
Perithecia coriacea cortici immersa, globoso-depressa, vertice atte- 
nuata, ostioloque erumpente papilleformi preedita, in sicco colla- 
bentia. Asci clavati, fixi grandes octospori. Paraphyses filiformes 
flaccide intertexte. Sporidia subbiserialia, majuscula ovata, epi- 
sporio hyalino crasso, endosporio papyraceo castaneo-fusco trilo- 
culari, loculis ineequalibus, superiore majore subhemispheerico, me- 
dio subgloboso, extime minore hemispheerico ascis vertice dehis- 
centibus copiose profluentia, atro inquinantia. 
I dedicate this genus to the memory of the late Dr. Massara, 
author of the ‘ Flora Valtellinese.’

It grows on the dead branches of the sycamore. 
The perithecia of this species are a millimetre in diameter, and 
grow under the soft bark of the young boughs of the sycamore, 
sometimes solitary, sometimes in pairs or in clusters of many in- 
dividuals. On their upper surface they are clothed with a fuligi- 
nous down, a peculiarity not included in the generic characters, 
because it is sufficiently distinguished by the episporium of con- 
siderable thickness and the form of the endosporium. 
The celebrated Link, in the ‘ Handbuch zur Erkennung, 1.c., 
has proposed a new genus among the Spheriacee, under the 
name of Spilobolus, characterizing it merely by the way in which 
the sporidia are evacuated from the perithecia. He refers to it 
Sp. inquinans, S. Xylostet and S. Tilie, three species which have 
no affinity together. Suffice it to say, Sp. Tilia belongs to the 
compound Spheria, and the part which Link and many other 
authors have described as a perithecium is nothing more than a 
stroma of a determinate figure.
