Original description
Coprinus herinkii Pilát & Svrçek in Ceská Mykol. 21: 137. 1967 (Revisio specierum sectionis Herbicolae). Holotype: Czechoslovakia: Bohemia, Vodñany, on grass, 12 Aug. 1938, J. Herink (PRM 499700).

Coprinus herinkii sp. nov. - Fig. 1. Syn.:? Coprinus microspermus Lange, Fl. Ag. Dan. 4: 112, 1939 (nomen nudum).
P i 1 e u s late campanulatus, exsiccatus 2,5 mm latus, dein explanatus, statu vivo probabiliter aibus, exsiccatus pallide brunneus, velo crasso e hyphis crasse tunicatis, aculeiformiter ramosis, in. squamulas areolatas, relativiter magnas, ambitu sat irregulares tectus. In rimis squamularum cutis pilei albida et distincte quam squamulae pallidior apparet.
S t i p e s rectus, 5-6 mm longus, 0,3 mm crassus (statu vivo probabiliter ca 0,5 mm crassus), albus, exsiccatus pallide brunneus, angulo recto insidens, quasi msitus, basi pilis setiformibus, hyalinis, baud crebris muni'tus, ceterum subglaber, solum apice minime (sub lente) albido-pruinosus.
L a m e l l a e sparsae, haud furcatae, ca 20.
V e l u m conspecte evolutum, e hyphis 6-8 µm crassis, conspecte lucem fran-gentibus, crasse tunicatis, cum ra,mulis brevioribus, aculeiformibus 1-2 µm crassis et 4-15 µm longis, apice angustatis vel acutatis, crasse tunicatis, lumine saepe solum aJigusto provisis constans.
H y p h a e   t r a m a e in statu adulto parum distinctae, deliquescentes, hyalinae vel minime brunneolae, haud crassae. Basidia statu adulto iam soluta.
S p o r a e copiosae, globosae et paulum subangulata'e, apiculo parum distinc-to provisae, superfice reliquiis subhyalinis perisporii agglutinalis instructae, obscure brunneae, sed pellucidae, parte interiori magis lucem frangenti et poro germanitivo tndistincto curata'e, 6-7,5 µm diam.
H a b. Unum carposoma bene evolutum ad folium emortuum graminis in silva 'Cernohaj' prope Vodnany, Bohemiae meridionalis, 12. VIII. 1938 Dr. Josephus Herink legit. Typus PR 499770. A d n o t a t i o n e s. Sporae huius speciei forma et dimensionibus sporas Coprini angulati sensu Lange (Fl. Ag. Dan.'4 : 115, tab. 157 D) similes sunt, qui teste Klibner et Romagnesi (Fl. anal. p. 384, 1953) Coprinum patouillar-dii var. Upophilum Heilc. et Romagnesi representat. Coprinus angulatus Peck nomen validum pro Coprino boudieri Quel. est. Coprinus microspermus ]. Lange (1939, 4:112) (nomen nudum) cum sporis globosis 6x5-5,5 u cum specie nostra fortasse identicus.

Observations:
Spores [20,1,1] 4.7--5.7 x 4.8--5.7 x c. 5 µm, rather dark red-brown, globose, somewhat lentiform, somewhat marbled; Q= 0.95--1.05, av. Q= 1.00; av. L= 5.3, av. B= 5.2 µm. Germ pore central. Basidia and pseudoparaphyses not noted. Pleurocystidia 75--95 x 12--20 µm. Cheilocystidia not found. Veil very thick-walled, 2--8 µm wide; walls up to 3 µm thick and not or slightly coloured. Clamp-connections probably present, difficult to see.

Notes: the wart-like ornamentation of the perisporium, mentioned in the original description, has not been observed on the spores, either in Congo-Red or in water. The diameter of the spores given by Pilát & Svr_ek (6--7.5 µm) is much larger than in the observations on the type.
