Observation 129452: Tubaria furfuracea (Pers.) Gillet
When: 2013-01-31
Herbarium specimen reported

Notes: Brown, hygrophanous cap changing to light tan. The caps ranged from 3-37mm. wide by 1-8 mm. high at center. The stipe at the base ranged from 2-6mm. diameter, and the length of the stipes was 5-25mm. Trama thickness was 1mm,at the center and the stipes were from 1-9mm. diameter at the apex. Shape of the pileus was convex to plane, becoming uplifted. There were some shallow, narrow pits on the disc in some specimens. Pilei were orbicular in top view, and the margins were decurved at first, then upturned in older specimens. On younger mushrooms the margin was entire and striate. the pilei were moist and shiny. The gills ranged from 1-5mm. wide , and were 15-20mm long.
Some of the caps had small “bumos” on them, and on older specimens the margin looks gyrose. The pileal surface was slightly scurfy.
THe trama was soft, moist, and felt “rubbery”. No detectable odors, and I didn’t taste them.
The gills were adnate, slightly descended the stipe, were pinkish-brown, narrow, and subdistant. Some of the gills seemed to erratically fork near the margin, but only a few of them. Lamellulae were also present.
The stipe attachment was central to eccentric (based on my measurements from the apex to the margin in several places). White, downy hyphae was attached to the base of the stipe. (basal tomentum)? The stipes were hollow and some were compressed. Stipe was equal to tapering slightly towards the base, and the stipe was very finely longitudinaly striate. The stipe was leathery in that I could bend it in half without breaking it. It/they were hollow.
Young specimens had a partial veil that left fibrils just below the apex. Not sure if it was a membranous partial veil or a cortina, as one membrane appeared to be splitting radialy. Maybe my glasses need to be cleaned? The growth habit was scattered, gregarious and cespitose. Found on wood chips and grass under a White Dogwood tree. The spore color is yellow-ochre. Methuen: P.5, C7. Bottom three photos of spores at 1000×. Each line is one micron.

Largent and Baroni describe the annulus as membranous or evanescent, leaving a ring-like zone, “Rarely cortinate.” This implies that some Tubaria species do possess Cortinas.

This collection was made on the corner of Owens street and Wyoming Ave. by sal’s pizza.

along the same road a mile or so north of a similar observation I had posted for December 2012.
Habitat is virtually identical.

Phil, I think your glasses are probably okay :-) The fleeting partial veil is sort of a cross between membranous and cortinate for this type… Miller calls it “fibrous” (in his description of T. heimalis, which is now considered a synonym of T. furfuracea). Some fruitings show no veil.
