Tulosesus impatiens (formerly Coprinellus impatiens) is a species of fungus in the family Psathyrellaceae. First described in 1821, it has been classified variously in the genera Psathyrella, Pseudocoprinus, Coprinarius, and Coprinus, before molecular phylogenetics reaffirmed it as a Coprinellus species in 2001. The fungus is found in North America and Europe, where the mushrooms grow on the ground in deciduous forests. The fruit bodies have buff caps that are up to 4 cm (1.6 in) in diameter, held by slender whitish stems that can be up to 10 cm (3.9 in) tall. Several other Coprinopsis species that resemble C. impatiens may be distinguished by differences in appearance, habit, or spore morphology.
The species was first described in 1821 as Agaricus impatiens by Swedish mycologist Elias Magnus Fries in his Systema Mycologicum.[2] In 1886, Lucien Quélet transferred the species to Coprinarius[3] (a defunct genus now synonymous with Panaeolus[4]) and then to Coprinus a couple of years later in his Flore Mycologique de la France.[5] In 1936, Robert Kühner segregated the genus Pseudocoprinus from Coprinus, including species that did not have deliquescent gills (that is, gills that "melt" into liquid), and he included Coprinus impatiens in this generic transfer. He later changed his mind about the taxonomic separation of Coprinus and Pseudocoprinus.[6] Gillet transferred the species to Psathyrella in 1936.[7] In 1938 Jakob Emanuel Lange published the new combination Coprinellus impatiens.[8] Despite the taxonomic shuffling, the species was popularly known as Coprinus impatiens until 2001, when a large-scale phylogenetic analysis resulted in the splitting of the genus Coprinus into several smaller genera, and the authors confirmed the validity of the generic placement in Coprinellus.[6] The specific epithet impatiens is derived from the Latin word for "impatient".[9]
A 2005 phylogenetics study proposed that C. impatiens was sister (closely related on the phylogenetic tree) to a large Psathyrella clade, and that consequently, the genus Coprinellus was polyphyletic.[10] A later (2008) study suggested, however, that these results were due to an artifact of taxon sampling—not enough species were analyzed to adequately represent the genetic variation in the genera. The 2008 study demonstrated that Coprinellus, including C. impatiens, was monophyletic, descended from a common ancestor. In their analysis, C. impatiens was most closely related to C. congregatus, C. bisporus, C. callinus, and C. heterosetulosus.[11]
The species was known as Coprinellus impatiens until 2020 when the German mycologists Dieter Wächter & Andreas Melzer reclassified many species in the Psathyrellaceae family based on phylogenetic analysis.[12]
The cap of the fruit bodies is initially egg-shaped, then conical to convex before flattening out, reaching diameters between 1.8 to 4 cm (0.71 to 1.57 in). It has deep narrow grooves reaching almost as far as the center of the cap. The surface color is a pale buff, tawny or cinnamon towards the center, but the color loses intensity when the mushroom is dry. The flesh is whitish, thin, fragile and barely deliquescent (auto-digesting). The gills are initially buff, then turn grayish brown. They are either free from attachment to the stem, or adnexed, meaning only a small portion of the gill is attached. The stem is whitish, very slender, and more or less equal in width throughout its length, or slightly thicker at the base; its dimensions are 7 to 10 cm (2.8 to 3.9 in) by 0.2 to 0.4 cm (0.08 to 0.16 in) thick. The stem surface of young specimens are pruinose—appearing to be coated with a minute layer of fine white particles; this eventually is sloughed off, leaving a smooth or silky surface. The odor and taste of the fruit bodies are not distinctive. The gills of this species do not autodigest with age, or barely do so; the fruit bodies tend to become more fragile with age.[13][14]
The spore print is dark brown. The spores are smooth, ellipsoid or almond-shaped, with a germ pore; they measure 9–12 by 5–6 μm. The spore-bearing cells, the basidia, are four-spored and tetramorphic (the spores lie on several different levels, and mature at different times). The cheilocystidia (cystidia found on the gill edge) are roughly spherical, 20–35 μm broad, or lageniform (flask-shaped), 36–64 by 10–15 μm, with the apex often rather acute, about 3–5 μm wide. Pleurocystidia (cystidia found on the gill face) are absent in this species.[13]
Coprinellus disseminatus resembles C. impatiens, but may be distinguished by its slightly larger fruit body, somewhat deliquescent gills, and tendency to fruit in smaller groups on the ground, rather than on or around rotting wood.[15] Also, C. disseminatus has smaller spores than C. impatiens, typically 6.6–9.7 by 4.1–5.8 μm.[16] C. eurysporus is similar to C. disseminatus but usually grows in groups on fallen branches, and has broader spores that measure 8.3–10.3 by 6.7–8.4 µm.[17] C. hiascens usually grows in small dense clumps, has narrower spores (typically 9–11 by 4.5–5.5 μm, and produces smaller fruit bodies.[13]
Tulosesus impatiens is found in North America and Europe[18] (including Germany,[19] Poland,[20] and Ukraine[21]) including northern Turkey.[22] In the Pacific Northwest region of the United States, it is found in Oregon and Idaho.[23] Fruit bodies grow solitarily, or rarely in small bundles, on forest litter in deciduous forests, especially ones dominated by beech.[18][24]

Coprinellus impatiens es una especie de hongo en la familia Psathyrellaceae. Fue descrito por primera vez en 1821, estuvo clasificado en diversos géneros: Psathyrella, Pseudocoprinus, Coprinarius, y Coprinus, antes de que un estudio molecular filogenético confirmara su pertenencia al género Coprinellus en 2001. El hongo se encuentra en América del Norte y Europa, donde los hongos crecen en el suelo en bosques caducifolios. Los cuerpos fructíferos tienen color ante y sus sombreros alcanzan hasta 4 cm de diámetro, sostenidos por un fino tallo blanquecino que pueden tener hasta 10 cm de alto. Varias otras especies de Coprinopsis que se parecen a C. impatiens pueden distinguirse por diferencias en la apariencia, hábito o morfología de las esporas.
Coprinellus impatiens se encuentra en América del Norte y Europa[2] (incluida Alemania,[3] Polonia[4] y Ucrania)[5] además del norte de Turquía.[6] En el noroeste de Estados Unidos se le encuentra en Oregón e Idaho.[7] Los cuerpos fruosos crecen solitariamente, o raramente en pequeños grupos, entre la hojarasca de bosques caducifolios especialmente los de hayas.[2][8]

Po raz pierwszy takson ten zdiagnozował w 1821 r. Elias Fries nadając mu nazwę Agaricus impatiens. Obecną, uznaną przez Index Fungorum nazwę nadał mu w 1938 r. Jakob Emanuel Lange, przenosząc go do rodzaju Coprinellus[1]. Synonimy naukowe[2]:
Władysław Wojewoda w 2003 nadał mu polska nazwę czernidłak szaroblaszkowy[3]. Badania z zakresu filogenetyki molekularnej wykazały jednak, że rodzaj Coprinus nie był taksonem monofiletycznym i należy go rozbić na rodzaje Coprinus (sensu stricto), Coprinopsis, Coprinellus, a także kilka innych[4]. Tak więc nazwa podana przez W. Wojewodę stała się niespójna z nazwą naukową.
Średnica 1,5-4 cm. U młodych owocników ma kształt walcowaty lub jajowaty, u dojrzałych szerokostożkowaty. Powierzchnia jest higrofaniczna i głęboko żłobkowana, niemal do środka kapelusza. Brzeg kapelusza ostry, wierzchołek zawsze pomarańczowy lub czerwonobrązowy, pozostała część kapelusza podczas suchej pogody jest szarocielista, podczas wilgotnej ma kolor od ochrowego do pomarańczowobrązowego[5].
Szerokie i szeroko przyrośnięte, o ostrzach jasnych i płatkowatych. U młodych okazów mają kolor kremowocielisty, ale szybko stają się coraz ciemniejsze; początkowo brązowoszare, później ciemnopurpurowobrązowe[5].
Wysokość 5-9 cm, grubość 2-4 mm. Jest walcowaty, kruchy i i pusty. Powierzchnia gładka, biaława i jedwabista z delikatnymi podłużnymi włókienkami. Podstawa trzonu w kolorze szarym i pilśniowata[5].
Cienki, białawy, bez wyraźnego smaku i zapachu[5].
Czarnobrązowy. Zarodniki elipsoidalne, cienkościenne, o ostrym wierzchołku. Rozmiar 9-12 × 5-6 μm[6].
Występuje w Ameryce Północnej i w Europie[7]. W Ameryce jest dość rzadki[6], w Polsce jego częstość występowania i rozprzestrzenienie wymagają badań[3].
Rośnie w wilgotnych lasach liściastych, głównie pod bukami, na glebach o odczynie obojętnym lub zasadowym[5].
