Hone: pezizales, piiacidiales and tuherales of minn. 71 



1. Plicariella polytrichi (Schum.) Lindau. Engler & Prantl, Nat. 



Pflanz. 1:2:180. 1897, 



Pcziza polytricJii Schum. Enum. Plant. Saell. 1:423. 1801. 



Barlaca polytrichi Sacc. Syll. Fung. 8: 113. 1889. 



Dctonia polytrichina Rehm, Rabh. Kryptofl. 1:3:1269. 1896. 



Gregarious, sessile, Heshy, saucer-shaped, -5 mm. in diameter; 

 margin entire, but wavy, smooth, thick ; hymenium orange-red ; ex- 

 terior lighter to whitish, pruinose ; spores globose, hyaline, smooth, 

 guttulate, 10 mic. in diameter; paraphyses very slender, not clavate, 

 but curved at the apex, and filled with orange granules and oil 

 globules. 



On the ground among moss; Becker, Aug. 1901, Freeman 1147; 

 Ramsey, Oct. 1907, Hone 938. 



There seems to be great confusion as to what P. polytrichi as 

 described by Schumacher, really was. Cooke (48, p. 29.), Gillet 

 (91, p. 50.), Phillips (162, p. 87.), Rehm (178, p. 927.), Lindau 

 (124, p. 180.), describe the spores as globose and smooth. Massee 

 (132, p. 109; 134, p. 371.) describes them as elliptical and finely 

 warted. In Grevillea, Massee gives synonyms and cites exsiccati 

 in the Kew sets. Upon examination of Roumeguere, Fung. Gall. 

 No. 40-45 in the Minnesota Herbarium, the spores prove to be ellip- 

 tical, acute, finely w^arted, 20-24 x 10-12 mic, which agrees with 

 Massee's description of P. polytrichi Schum. The Minnesota speci- 

 mens agree with Lindau and Rehm's interpretation of the size and 

 form of the spores as well as of the cup, for P. polytrichi Schum.
