32. M. brassicaefolius Schweinitz, Naturforsch. Ges. Leip- 
zig Schrift. 1: 93. 1822; Fries, Elenchus Fung. 1: 60. 1828; 
Еріст. 502. 1838; басе. Syll. Fung. 6 : 420. 1888. 
Type: not known to be in existence unless the portion re- 
ceived by Fries has been preserved in Herb. Fries. 
Fructification resupinate, widely effused, membranaceous, 
easily separable, run through with rhizomorphie veins, drying 
warm sepia (fuscescens or olivaceo-fuscens of Fries), the 
margin undulate; hymenium even towards the margin and in 
young specimens, porose-sinuate аё the 
i? center by the accumulation of folds; in struc- 
СО (D — ture 200-300 и thick, 2-layered, with (1) a 
Fig. 30 narrow layer next to substratum, composed 
M. brassieaefolius. Of loosely interwoven, pale-colored, nodose- 
o oh Bh аа. septate hyphae up to 5 u in diameter, more 
or less шеги ед, and with (2) a broad layer 
reaching to the hymenium, of densely interwoven, hyaline, 
nodose-septate hyphae 34-4 и in diameter, with occasional 
colored hyphae intermixed; spores even, 10-12 6-8 и, cream- 
color under the microscope; no cystidia. 
Fructifications up to 10 еш. in diameter in specimens seen, 
but published as 40-50 em. 
On wood in cellars. Massachusetts to Louisiana. Winter. 
Since no specimen of M. brassicaefolius is in existence in 
Herb. Schweinitz, nor could be found there in 1856 when Berk- 
eley and Curtis published their ‘Commentary on Schweinitz, 
Synopsis Fungorum,’ it is very fortunate that a specimen was 
sent by Schweinitz to Fries, who compared it with the orig- 
inal description, noted the color, which had not been stated 
by Sehweinitz, and drew up and published in ‘Elenchus 
Fungorum’ a revised description of this species, in which its 
characters are compared with those of the other species of its 
section, viz., M. lacrymans, M. pulverulentus, M. papyracens, 
M. umbrinus, and M. squalidus. The specimens of М. bras- 
sicaefolius distributed in Ravenel, Fungi Car. 2 : 23, agree well 
with the descriptions of this species, were from the same 
general region and in a similar location, and they are not 
referable to any other species. I have based my conception
