British Columbia: Capilano River Regional Park, District of North Vancouver, near Giant Fir Trail. Elev. 90 m
49.4° N, 123.1° W,
Datum: unknown. Coordinate Source: Verbatim from Collector/Sheet.
Moist, under a fallen hemlock tree; young maple trees found nearby, gregarious (in a group of ten); ground (covered by moss) cap size (in diameter) 11cm, 9cm, 5cm, 3.5cm; shape plane when young, depressed when mature; color brown with the center darker brown; surface smooth and moist, not hygrophanous; margin incurved when young, undulating when mature; gills decurrent, close, white to cream, unequal with short gills; stipe size (in length) 14cm, 13cm, 10cm, 8.5cm (in thickness) 2cm, 1.5cm, 1cm, 0.7cm; central, solid, light brown, end enlarged and slightly curved; annulus (-), volva (-), white mycelium attached at the end spore print white; odor mild, taste mild, latex (-), staining (-) basidiospores 8.75~3.75 micrometers, spindle-shaped, with small notche at both ends, not stained with Melzer's agent(inamyloid, indextrinoid), with four spores on each basidium; cystidia ca.30 micrometers long, elongated, partitioned into small segments like an ear of corn (see drawing); A basidium with elongated sterigmata was also found. (see drawing) They may be the "germinated sterigmata" mentioned in "North American Species of Clitoybe" by H. E. Bigelow. According to "North American Species of Clitocybe" by H.E.Bigelow, "C.avellaneialba is rarely confused with any other, except perhaps C.clavipes." However, in "Mushrooms Demystified" by D.Arora,it could be confused with C.leopardina. Therefore, I am going to make comparisons with these two species. 1. Clitocybe leopardina (no specimens found in the herbarium) differences from C.avellaneialba, caps smaller (5-10cm), viscid brown that becomes paler in age, gills pinkish buff with grayish tint that becomes yellower in age, stipe shorter (3-6(-8) cm), thinner (1.5-2.5cm), basidiospores more broadly ellipsoid (4.5-6 ~3-4ƒÊm); None of these characters applied in my specimens, especially the color change in the cap and the shape of spores. Thus, there is very little possibility that my specimens are C.leopardina. 2. Clitocybe clavipes differences from C.avellaneialba, caps smaller (2-10cm), grayish-olive brown, gills white that turns yellowish buff in age, stipe shorter (2-7cm), thinner (0.5cm-1.2cm), odor fragrant (grape-like); To summarize, C.clavipes is smaller than C.avellaneialba in general and the former has more yellowish gills. I made sure of these traits by comparing specimens at the herbarium. (C.clavipes : F12286, 13380, 15647, 15686, 15710. C.avellaneialba: F10261, 12011, 12151, 12213, 13607, 17827, 17828) I also had the impression that C.clavipes had a lighter brown cap than C.avellaneialba. In addition, comparing the specimens above, I noticed another possible differential character. The decurrent gills of C.avellaneialba gradually merge into the ridges on the stipe, which are formed during the drying process, whereas in C.clavipes, one can see a clear line that separates gills from the stipe. It is not merely a difference in color between the gills and the stipe, but a distinct termination of gills at the point of attachment on the stipe. The gradual transition of gills and stipe was found in the online images of the type specimen of C.avellaneialba at the herbarium of the New York Botanical Garden. http://207.156.243.8/emu/vh/specimen.php?irn=731305; From the observations above, I conclude that my specimens are Clitocybe avellaneialba. Three of the specimens were collected in the UBC Endowment Lands. There was one collected on Saturna Island (further detail unknown,) ca.48N, 123W. One from Squamish, 49.45'N, 123.10'W. One from Maple Ridge Malcom Knapp Research Forest, 49.16'N, 122.30'W. Therefore, C.avellaneialba seems to grow diffusely, at least in southern coastal British Columbia. Howard E.
