102 TWENTY- SEVENTH REPORT ON THE STATE MUSEUM. 



Pestalozzia Marije Clinton n. sp. 



Spots arid, brown or cinereous with a brown margin ; 

 pustules minute, scattered, erumpent, black ; spores fusi- 

 form, five-septate, the four intermediate cells colored, a 

 terminal cell and a long seta at each end hyaline, length of 

 spore exclusive of the setae .0007'-. 001'. 



Leaves of Rhododendron maximum. Buffalo. Clinton. 

 Forestburgh. September. (Plate 2, figs. 1 and 2.) 



This is apparently a rare species. In all the specimens 

 that I have seen the spots are large and situated at the apex 

 of the leaf. The epidermis is ruptured in a somewhat stel- 

 late manner. The peduncle sometimes remains adhering to 

 the spore, thus giving the appearance of two setae at one 

 end. 



CORYNEUM TRISEPTATUM U. Sp. 



Spots large, brown or cinereous ; stroma obsolete ; sori 

 scattered, minute, erumpent, black ; spores oblong-pyriform^ 

 .0006-.0007' long, at first colorless and biseptate, then tri- 

 septate with one apical and two basal cells hyaline, the 

 remaining cell broad and colored ; peduncle about as long 

 as the spore, easily separating. 



Living leaves of Rhododendron maximum. Forestburgh. 

 September. 



I am not acquainted with Coryneum Rlwdodendri Schw. 

 which also inhabits Rhododendron leaves, but judging from 

 the description it must be distinct from our plant for it is 

 said to have thick septate pedicels and no mention is made 

 of the most remarkable feature of the spores, the broad 

 colored central cell, sharply contrasted with the two hyaline 

 cells below it and the single one above it. 



Spiloc^ea concentrica Schw. 



Decaying squashes. Albany. November. 



Helicosporium olivaoeum n. sp. 



Flocci black, subulate, simple, septate, the articulations 

 several times longer than broad ; spores slender, coiled, 

 simple or obscurely septate, olivaceous. 



Hemlock wood. North Greenbush. October. 



It forms thin olivaceous patches. Closely related to H. 

 vegetum, from which the long articulations of the fiocci 

 and the obscurely septate or simple spores seem to sepa- 

 rate it.
