Chromosera lilacifolia var. totililacicolor Lebeuf, G. Cartier, Grootmyers & Lodge, var. nov. Fig. 3E View FIGURE 3
MycoBank #:—MB 855448
Etymology:—Toto- entirely, lilacicolor—lilac colored.
Type— Canada. Québec Province: Sainte-Marguerite-du-lac-Masson, rue du Lac-Clair, 46.09239, -74.05392, on Pinus strobus log, Gwenaël Cartier S.N., 25 July 2014, HRL1723 (DAOM985251, holotype)
Diagnosis:—Entirely lilac-colored. Differs from the type variety in lacking yellow pigments in the pileus and stipe.
GenBank: — PQ182943
Distribution:—Only known from three collections at the type locality, Lac-Charlebois, Québec, Canada.
Habitat:—Growing on Pinus strobus logs.
Additional specimens examined: — CANADA, Québec Prov., Sainte-Marguerite-du-lac-Masson, rue du Lac-Clair, on Pinus strobus log, Gwenaël Cartier S. N., 6 July 2013, photo record only (https://www.flickr.com/photos/14486802@ N02 /9234939698) ; ibid, 12 July 2015, photo record only (https://www.flickr.com/photos/14486802@ N02 /19480004699) .
Comments: — Except for the absence of yellow pigments, the macroscopic and microscopic features of this variety are the same as those in the type variety of C. lilacifolia . The molecular phylogeny also indicates that they represent the same species, with C. lilacifolia var. totililacicolor DAOM 985251 differing from other C. lilacifolia isolates only by an additional C in ITS2.

Etymology:—Named in honor of Dr. Lorelei L. Norvell who co-described the genus Chromosera .
Type:— USA, Washington, Pierce County, Mt. Rainier Nat. Park, Ipsut Creek, 46.97056, -121.83195, 245 m elev., 11 November 1993, Scott Redhead and Lorelei Norvell LLN 93.11.11-7, (WTU-F-001648, holotype).
Reference specimen:— Canada, British Columbia, Vancouver, University of British Columbia Lands , 12 October 1998, S. A. Redhead (8038) and K. Seifert DAOM 985252 View Materials ; cultured as DAOMC225985 , GenBank PP 853161
Diagnosis:—Occurring in northwestern North America, usually differing from Eurasian C. cyanophylla in having paler lamellae that are rosy lilac versus bluish lilac, and in ITS sequences. Differing from C. lilacifolia in eastern North America by longer spores (> 6.5 µm) and ITS sequences.
Description: — Adapted from Redhead, Ammirati & Norvell. 1995. Sydowia X: 162–164. Pileus 3–25 mm diam., convex with a flattened to depressed center, glabrous, translucent-striate, darkest in center, pale luteous to amber, honey color, olivaceous-buff, to Cream color to Naples yellow with faint rosy vinaceous, pale rosy vinaceous, rosy vinaceous or Pale Lilac, fading with age (or losing lilac pigments with sunlight and drying). Lamellae arcuate-decurrent, pale vinaceous, rosy vinaceous, or Pale Lilac, fading with age, edges concolorous, moderately spaced, 1–2 lengths of lamellulae inserted. Stipe 10–30(–45) x 1–2.5 mm, equal above a slightly swollen base, cartilaginous, hollow, viscid, amber with a grayish rose to vinaceous tinted apex, frequently with vinaceous to lilac tints at base. Odor not significant.
Basidiospores 6.5–9(–11) x 3.5–4.5 µm, amygdaliform to ellipsoid, with prominent tapered apiculus, thin-walled, smooth, hyaline, inamyloid, not cyanophilous. Basidia 20–25(–29) x 4–5(–6.5) µm, clavate, 4-sterigmate, lacking siderophilous granules. Pleurocystidia and cheilocystidia absent. Pileipellis a thin collapsed ixotrichoderm, hyphae 3–5 µm diam., hyaline, inamyloid, smooth, thin-walled, clamped, embedded in a thin slime which easily disperses, sparsely covered with small, yellowish, refractive pigment globules 1.5–2 µm diam. Subpellis poorly differentiated from the trama except for increased concentrations of extracellular and possibly intracellular pigment corpuscles 6–7 µm diam. consisting of radially arranged globules around a colorless core. Pigment bodies present in only relatively recent collections—noted up to 1 year after drying but apparently volatilizing or degrading in herbarium specimens hence lacking in older material—subhyaline to faintly yellow in water, becoming bright yellow in dilute NH 4 OH sol. or Melzer’s reagent. Pilear trama hyphae mostly 5–15 µm diam., thin-walled and loosely packed, hence many collapsed in rehydrated material, hyaline except for scattered pigment globules and corpuscles, walls weakly to moderately dextrinoid. Lamellar trama more or less regular but becoming slightly disorganized with age, hyphae mostly 5–10 µm diam., similar to those of the pilear trama, mixed with fewer pigment corpuscles, moderately dextrinoid.
Distribution: — Western North America.
Habitat: — Growing on conifer wood.

Comments: — The rosy lilac pigment typically found in the mycelium at the base of the stipe is also produced in multispore derived agar culture, where both pigments — yellow and rosy lilac — are expressed in different parts of the mycelium ( Fig. 3D View FIGURE 3 ). This species is difficult to distinguish macroscopically from the Eurasian C. cyanophylla and the eastern North American C. lilacifolia . However, its lamellae are usually paler, with a rosy hue rather than the bluish lilac of the former, and it usually exhibits paler lamellae and a smaller pileus diameter to stipe length ratio than the latter.
The spores of C. loreleiae are longer than those of C. lilacifolia in eastern North America (> 6.5 µm) but spore dimensions are similar to those of Eurasian C. cyanophylla . Besides the differences in geographic ranges, divergence in ITS sequences is useful for separating C. loreleiae and C. cyanophlla . For example, in ITS1 beginning ca. 58 bp before the 5.8S region, the sequence in C. loreleiae is aaaaa-atCyTgaatgt-Gatt compared to aaaaaCatTtTgaatgtAAatt in C. cyanophlla . Chromosera lilacifolia has a different ITS1 motif, AAAA-CTTTAATGAATGT-GATT, as does the European C. ambigua , AAAA- -TTT-TTGAATGT-CATT. The provisional species names Chromosera “cyanophylla- CA01” and Chromosera “ CA-01” have previously been used for this species in GenBank and iNaturalist.
Singer (1942) suggested that the species Murrill (1913) described from Oregon as Clitocybe violaceifolia was related to A. lilacifolius , raising the possibility of a prior name for Chr. loreleiae . However, the first author studied the holotype of Cl. violaceifolia (NY 657675) and excluded it from Chromosera based on the more robust basidiomes lacking yellow pigments. ITS sequence data generated from the type (GenBank OR886357) also supports Murrill’s placement of this species in Clitocybe sensu stricto distant from Chromosera . Additionally, the holotype of Cl. violaceifolia was reported as growing on Quercus wood while Chr. cyanophylla , Chr. loreleiae , and Chr. lilacifolia are all found growing exclusively on the wood of conifers.
The gross morphology and microscopic features of the holotype of C. loreleiae (WTU-F-001648) are illustrated (as Chromosera cyanophylla ) in Redhead et al. (1995).
Additional type examined:— Clitocybe violaceifolia Murrill. USA. Oregon: Marion Co., near Salem, on decaying Quercus wood, 7 June 1911, Morton E. Peck s.n. (NY 657675, holotype).
