Sowerby, in his comment on plate 257, _Eng. Fungi_, says: "It appears to consist of branching threads affixed to the deal and holding a dense mass of sooty powder. Over the whole is a thin, deciduous pellicle." This description seems to be applicable to nothing else. The figure amounts to little. Fries recognizes the English description, as does Rostafinski, but both authors adopt the later name given by Albertini and Schweinitz, simply because of the excellent detailed description found in the _Conspectus_. 2. AMAUROCHAETE TUBULINA (_Alb. & Schw._) _Macbr._ PLATE XX., 6 and 6 _a_. 1805. _Stemonitis tubulina_ (Alb. & Schw.), _Cons. Fung._, p. 102. 1825. _Lachnobolus cribrosus_ Fr., _Syst. Orb. Veg._, p. 14. 1912. _Amaurochaete cribrosa_ (Fr.) Macbr., _Com. in litt._ to Herbaria, Harvard, etc.[35] 1917. _Amaurochaete cribrosa_ (Fr.) Sturg., G. Lister, _Jour. Bot._, LVIII, p. 109. Plasmodium at first transparent then white then rosy, ashen or grey finally deepening to jet-black; the aethalium even, thin, variable in extent from one to ten centimeters, covered by a distinct but thin transparent cortex, papillate, extended laterally but a short distance beyond the fructification, fragile, soon disappearing; hypothallus long-persistent, thin, silvery, supporting the capillitium as if by stipes, short slender columns, irregular plates, expansions, etc.; the capillitium an intricate network, very abundant, elastic, on fall of the peridium appearing like tiny tufts of wool, the meshes large, but formed as in _Stemonitis_, persistent, dull black; spores, under the lens, dull olivaceous black, minutely roughened, 12-14 mu. This species differs from the preceding, already well known, especially in the capillitial characters. In the older species the capillitial branches fray out, and are only sparingly united into a net extremely lax. In the present form the net is the thing, common to all sporangia. The total effect is to lend to the blown-out aethalium a woolly appearance, entirely unlike that of its congener under the same conditions. But until fructification is quite mature, the presence of the collaborating sporangia below is indicated, suggested, by the papillose upper surface.
