Coprinus pseudofriesii sp. nov.

(exsiccatus 5-7 mm), campanulatus, dein explanatus, margine revolutus, albidus, dein pallide avellaneo-brunneus, postremo e sporis subniger, tenuiter carnosus, superficie velo obductus. Hoc dein in squamulas irregulares, pallide avellaneo-brunneas, cute pilei pallidiori, albido insidentes solutum et postremo fere evanescens.

Herink 332/41 sub Coprino phaeosporo Karst.) Typas PR 626346. - Bohemia septentrionalis: Pelesany prope Masov (distr. Tumov), ad caules Lolii temulenti putridos ad viam, 18. VII. 1948, leg. J.

A d n o t a t i o n e s. Hie fungus habitu Coprino friesii Quel. valde similis sporis distincte minoribus veloque magis evoluto e hyphis crassiusculis, colora-tis dignoscitur. (Coprinus friesii Quel. hyphas veli hyalinas habet). Coprinus phaeosporus sensu Kuhner et Romagnesi verisimiliter cum fungo nostro identicus est, sed non C. phaeosporus var. solitarius J. Lange, qui sporas diversas habet [cf. Coprinus solitarius (]. Lange) Pil. et Svr.]. Coprinus phaeosporus Karsten 1881 ut in Symbolis ad Mycologiam Fennicam 8 : 9, IX : 48 (teste Sac-cardo, Syll. Fung. 5 : 1105, 1887) descriptus est, in horto in urbe Mustiala' ad radices putridos graminum lectus, praesertim carposomatibus caespitosis sporisque ellipticis, bruneis, impellucidis, 9-15 x 4-9 µm magnis dignoscitur.

Coprinus pseudofriesii Pil. et Svr. - Bohemia cenrralis: Praha-Divoka Sarka, 22. VII. 1941 leg. J. Herink (typus). Observations:
Spores [40,1,1] 6.3--8.0 x 5.2--6.7 µm, medium red-brown, ovoid or ellipsoid; Q= 1.10--1.40, av. Q= 1.25; av. L= 7.1--7.3, av. B= 5.8--5.9 µm. Germ pore central, c. 1.3 µm in diameter. Pleurocystidia 50--100 x 10--15 µm. Veil thick-walled, 2--10 µm wide, walls up to 1.5 µm and pale yellow-brown. Clamp-connections present.

Notes: in the original description the size of the spores is given as 5--5.5(--6) x 4--4.5 µm. This size does not agree with the observations on the type material.
