CLASSIFICATION OF FOSSIL FUNGI 483 



structures interpreted to be fossil perithecia may not be perithecia, 

 since asci and paraphyses are rarely preserved. This fact is illus- 

 trated by Salmon's (1903) comments. He stated that the globoid 

 bodies which Pampaloni (1902) described as appendaged perithe- 

 cia of Uncinulites and Erysiphites, and which he examined, are 

 merely spiny spores. 



1. Protomycetaceae 



Frotomy cites proto genes W. Smith occurs on Lepidodendron 

 roots from the Coal Measures. 



2. Erysiphaceae 



Erysiphites metilli Pamp., E. protogaens Schmalhausen, and Un- 

 cinulites baccarinii Pamp. are said to occur in the Miocene, but 

 Salmon (1902) thinks they are from the Eocene. 



3. Perisporiaceae 



The Genus Perisporites, with three species, was created by Felix 

 from Eocene and Miocene rocks. 



4. Microthyriaceae 



Fhragmothy rites eocenica Edwards, Microthy rites dy sod His 

 Pamp., which looks like an Asterina, and Xylomites asteriformis. 

 Braun, occurring on some cycad-like plant, represent this family. 



5. Aspergillaceae 



Fenicillites curtipes Berk, occurs as a well-preserved fungus in 

 amber from the Eocene. 



6. Hysteriaceae 



This family is represented by Hysterites ancinitis Matth. from 

 the upper Devonian and H. cordiatis Matth. from the Permian 



and Carboniferous. 



7. Phacidiaceae 



Approximately 50 species of leaf-inhabiting species assigned to 

 Meschinelli's genera Phacidites and Rhytismites from the Tertiary 

 and Quaternary have been described. 



8. Stictidiaceae 



Stegites poacitum A. Br., described from the Miocene, occurs 

 in flecks on grass leaves.
