nothing in the description, which is very general, to exclude it except 

 the spore and ascus measurements, which are larger than ray findings 

 (26 by 220/it for the asci, and 20 by 28/a for the spores). The measure- 

 ments given by Ilarkness for No. 102 (12 by 80 for the asci and 12 

 by 18 for the spores) likewise debar this material from that species. 

 There is no mention in the descriptions by Harkness of either G. 

 Coopcri or G. hrunncola (the type of the latter being cited under No. 

 102, Harkness, 1899, p. 270) of the peculiar characteristics of Nos. 

 10& and 102 as I found them ; and therefore I feel justified in the sup- 

 position that in the various handling received by the Harkness 

 material, labels have been shifted or specimens otherwise confused, 

 and 102 probably does not represent the type of G. hvnnneola. The 

 latter is known to us only in the brief description of it by Harkness 

 (Proe. Calif. Acad, of Sci., 3d ser., vol. 1, no. 8, p. 270), and therefore 

 its present status cannot be defined. 



Under 10&, entire specimens are found ; but under 102 the material 

 is discovered to be in three or four pieces each measuring about 18 mm. 

 in diameter. Whether these all belonged originally to a single speci- 

 men or to more cannot be decided with certainty, and therefore the 

 size of the specimen cannot be definitely determined. The material 

 under 102 also has been attacked by the larvae of some insect, and 

 ver}^ little remains from which to determine the structure. However, 

 as far as it can be made out, it resembles 10& very closely, the measure- 

 ments are identical, and the peculiarly constricted internally annulate 

 asci, found in no other species observed, are very conspicuous in both. 



HYDNOTRYOPSIS, gen. nov. 



Aseocai'p siil)globose, compact, more or less lobed and wi-inkled, 

 without external opening ; cortex sometimes extending deeply into in- 

 terior ; gleba composed of minute, irregular folds, more or less joined, 

 forming complex system of veins separating canals and chambers; 

 hymeninm of regular palisade of asei, lining walls of canals and 

 <jhambers ; asci cylindrical, 8-spored ; spores ellipsoid, papillose. 



This genus belongs, apparently, in phylogenetic line with the an- 

 giocarpous forms, Geopora and Balsamia, for very careful search has 

 failed to reveal external openings from the hymenium. The exceed- 

 ingly fine folding of the gleba and wrinkling of the surface made this 

 point a difficult one to determine, but sufficient material was available 

 to make sections of every portion of the ascocarp. The closest, most
