Galerina hybrida
Galerina hybrida Kühner
Two collections:
-
1. Gregarious (5) in a Sphagnum carpet, with no conspicuous plant associates – at base of hydroelectric tower in a large raised bog, Little Lepreau, New Brunswick (24-07-20/01).
-
Pileus not seen when young, broadly convex to slightly depressed, with a large rounded umbo, lightly striate, smooth, dry, glabrous, medium orange brown (HSV15:60:60-70), hygrophanous and fading to pale yellow orange (HSV40:20:100), 17-24 mm in diameter. Stipe equal, not swollen at the base, pale yellow orange (HSV40:05-10:100), finely white pruinose at the apex and more sparsely so below, dry, hollow, 50-64 X 2-3 mm. Lamellae red brown (HSV35:40-60:90), close, adnexed, finely white-marginate. Veil not seen. Flesh concolorous with the surface tissues, with a nondescript odour and taste.
Basidiospores orange brown in spore print, narrowly ovoid, often with an apical umbo, coarsely roughened, without a plage, not dextrinoid, 7.6-10.4 x 4.3-5.2 μm, Q = 1.70-2.14 (average[50]: 9.1 x 4.7 μm, Q = 1.92). Cheilocystidia forming a continuous sterile margin, embedded in a gummy substance, with a slightly swollen to unswollen stipe terminated by a prominently swollen capitulum, with a basal clamp connection, 30.9-76.7 x 3.6-8.3 μm, with capitulum 4.4-25.0 x 3.8-11.5 μm. Pleurocystidia lacking. Caulocystidia abundant near the apex of the stipe, similar to the cheilocystidia but often more swollen toward the base and with capitulum more regularly spherical, with capitulum surrounded by a layer of gummy material, 29.0-37.9 x 4.1-11.8 μm, with capitulum 5.4-8.9 μm in diameter. Pileipellis a thin cutis of brown encusted hyphae. Clamp connections present on nearly all hyphae, often difficult to observe on the pileus tramal hyphae.

Pileus broadly convex, with an inconspicuous low rounded umbo, lightly striate, dry, glabrous, orange brown (HSV30:60:60-70), 10-16 mm in diameter. Stipe equal, not swollen at the base, pale yellow orange (HSV40:05-10:100), finely pruinose at the apex and more sparsely so below, dry, hollow, 43-82 X 2 mm. Lamellae pale yellow orange (HSV40:10:100), subclose, adnexed, not marginate. Flesh concolorous with the surface tissues, with a nondescript odour and taste.
Basidiospores bright rusty orange brown (HSV30:70:80) in spore print, ovoid to amygdaliform, usually with a small apical umbo, coarsely roughened, not strongly dextrinoid from the spore print but more clearly so when still on the lamella, darkening in KOH, 8.3-11.0 x 4.7-5.7 µm, Q = 1.68-2.06 (average[47]: 9.6 x 5.1 µm, Q = 1.86). Cheilocystidia forming a continuous sterile margin, lecythiform, with a conspicuously swollen capitulum, with a basal clamp connection, 38-56 x 5.2-8.0 µm, with capitulum 4.5-6.3 µm in diameter. Pleurocystidia lacking. Caulocystidia produced in dense clusters on the upper part of the stipe, lecythiform, similar to the cheilocystidia. Clamp connections present on almost all septa.
Both collections differ Europen descriptions of G. hybrida in having narrower basidiospores. In Smith and Singer (A Monograph On The Genus Galerina Earle, Hafner Publ., New York, 1964) it is closest to G. tibiicystis, a species those authors considered to be highly variable. Within that species they discussed a narrow-spored variant which may represent G. hybrida and possibly the collections described here. The basidiomata of Collection 24-07-20/01 were not in very good condition, so details of the gross appearance are incomplete. The gummy material surrounding the caulo- and cheilocystidia in Collection 24-07-20/01 was not seen in Collection 24-07-20/03 and may possibly be due to aging.

2. Scattered (2) in Sphagnum carpets at the wet margin of a large raised bog, Little Lepreau, New Brunswick (24-07-20/03).
