DOUBTFUL SPECIES 
Pleurotus connatus (Berk. & Curt.) Sacc. Syll. Fung. 5: 341. 1887. (Agaricus (Pleurotus) 
connatus Berk. & Curt. Proc. Am. Acad. 4: 115. 1858.) Described from specimens col- 
Jected on decayed wood on an island in Bering Strait. The type has not been examined. The 
name is preoccupied. 
Pleurotus glandulosus (Bull.) Quél. Champ. Jura Vosg. 332. 1873. (Agaricus glandulosus 
Bull. Herb. Fr. £1. 426. 1788.) Reported from North Carolina by Schweinitz and usually con- 
sidered a variety of P. ostreatus. ‘The specimen figured in Bulliard’s plate is almost black in 
color with a stipe like that of C. cornucopiae, so that it is impossible to say definitely just where 
the species belongs. 
Pleurotus Micheneri (Berk. & Curt.) Sacc. Syll. Fung. 5: 344. 1887. (Agaricus (Pleu- 
rotus) Micheneri Berk. & Curt. Ann. Mag. Nat. Hist. II. 12. 420. 1853.) Described from 
specimens collected on decayed wood in Pennsylvania. ‘The pileus is less than 2 cm. broad 
and infundibuliform. Both it and the distant, decurrent lamellae are pale-yellow, while the 
slender stipe is white and 5 cm. long. 
Pleurotus mutilus (Fries) Sacc. Syll. Fung. 5: 350. 1887. (Agaricus mutilus Fries, 
Syst. Myc. 1: 191. 1821.) Reported from California by Harkness, who may have mistaken 
an eccentric form of Clitocybe dealbata for it. 
Pleurotus Pometi (Fries) Quél. Champ. Jura Vosg. 78. 1872. (Agaricus Pometi Fries, 
Epicr. Myc. 132. 1838.) Reported from North Carolina by Curtis and from California by 
Harkness. It occurs on apple trunks in Europe. 
Pleurotus pulvinatus (Pers.) Sacc. Syll. Fung..5: 355. 1887. (Agaricus pulvinatus Pers. 
Syn. Fung. 370. 1801.) Reported on pear trunks in New England by Sprague and Ciirtis. 
A. pulvinatus Bolt. is Vaginata plumbea. 
Pleurotus putredinis (Berk. & Curt.) Sace. Syll. Fung. 5: 354. 1887. (Agaricus (Pleurotus) 
putredinis Berk. & Curt. Jour. Linn. Soc. 10: 287. 1868.) Described from very small, immature, 
densely cespitose specimens collected by Wright on dead wood in Cuba. ‘These type specimens 
are still at Kew, and with them on the same sheet are three very much larger pilei from Cuba 
bearing no number, which evidently represented the mature form of A. putredinis in Berkeley’s 
opinion. ‘he species is represented at Paris by this same large form, which is not distinct 
from C. commiscibilis. If the small typical specimens should be connected definitely with the 
larger pilei, A. putredinis would then become a synonym of C. commiscibilis. 
Pleurotus salignus (Pers.) Quél.-Champ. Jura Vosg. 332. 1873. (Agaricus salignus Pers. 
Syn. Fung. 478. 1801.) Reported from most of the eastern United States, but apparently not 
specifically distinct from P. ostreatus. We have forms occurring here on willow that very 
closely resemble those referred to this species in Europe. Cooke’s plate 228 (282) represents 
these forms very well.
