Limacella illinita var. argillacea

name	Limacella illinita var. argillacea
name status	nomen acceptum
author	H. V. Sm.
english name	"Clay-spotted Slimy Stem"
intro	The following is based on the original description of H. V. Smith (1945 ).
cap	The cap is 65^± mm wide, with disc Verona Brown, shading to Cinnamon Buff or paler at margin, with low broad umbo, and glutinous; its flesh is white and thin; its maring is nonstriate; and its volva is present as a colorless, unchanging slime.
gills	The gills are free, cream-white, 1^± mm broad, and have an edge that is very slightly undulate. Short gills were not described.
stem	The stem is about 75 × 8 mm, Cinnamon Buff, narrowing upward slightly, and glutinous; no bulb was described; and the flesh is white. The ring is either absent from the beginning or becomes difficult to see. The volva is present as a transparent, colorless to gray slime and is unchanging.
odor/taste	Odor and taste were not described for this mushroom.
spores	Spore measurements were not reported in the original description.
discussion	The original material of this variety was collected in the Pacific Coastal states of the U.S., under conifers. H. V. Smith (1945 ) wrote, "This variety is distinguished by the dull-brownish tinge on disc and stipe in both fresh and dried condition, but the colors are by no means so pronounced as in either L. glischra or L. kauffmanii." Unfortunately, she provided no microscopic character data—simply saying that such characters were as given for the type variety.—R. E. Tulloss

intro

The following text may make multiple use of each data field.

The field may contain magenta text presenting data from a type study and/or revision of other original material cited in the protolog of the present taxon. Macroscopic descriptions in magenta are a combination of data from the protolog and additional observations made on the exiccata during revision of the cited original material.

The same field may also contain black text, which is data from a revision of the present taxon (including non-type material and/or material not cited in the protolog). Paragraphs of black text will be labeled if further subdivision of this text is appropriate.

Olive text indicates a specimen that has not been thoroughly examined (for example, for microscopic details) and marks other places in the text where data is missing or uncertain.

The following material is derived from the protolog of the present taxon.

pileus

protolog: 65^± mm wide, with disc Verona Brown (R), shading to Cinnamon Buff (R) or paler at margin, with low broad umbo, glutinous; context white, thin; margin nonstriate; gluten layer colorless, unchanging.

lamellae

protolog: free, density not described, cream-white, 1^± mm broad, with edge very slightly undulate; lamellulae not described.

stipe

protolog: 75 × 8 mm, Cinnamon Buff (R), narrowing upward slightly, glutinous; bulb not described; context white; partial veil obsolete; gluten layer hyaline to gray, unchanging.

information not provided. [Smith was apparently unaware that she had created a new name; and a lectotype designation is required.—ed.]

discussion

Smith clearly believed that she was creating a new combination, not a new epithet. The Friesian source cited is a list of colors that sometimes were observed by him to occur on material of L. illinita—the words were not proposed epithets. Consequently, Smith (1945) was neither recombining or validating a previously existing epithet and must be treated as the author of the present taxon. Since Smith apparently reviewed material of her var. argillacea from California and Oregon, original material may exist from which a lectotype could be selected. Patricia Rogers (MICH) has informed me that there are six collections bearing the name L. illinita var. argillaceae and dated from 1935 to 1938 in MICH. These all have A. H. Smith collection numbers and come from the appropriate time period to be considered syntypes. Four of these collections have site information indicating they were collected in California. Two of the collections lack locality data. All appear to be syntypes. I have asked for the material to be sent to me on loan.

Synonymy of the present name with L. illinita f. ochracea was proposed by Neville and Poumarat (2004). However, L. illinita f. ochracea (E.-J. Gilbert) Konrad & Maublanc is also based on a single adjective in the same Friesian sentence; and, in its case, lacks original material. In RET's opinion the latter name is best considered a nomen dubium and its use abandoned.

protolog: "This variety is distinguished by the dull-brownish tinge on disc and stipe in both fresh and dried condition, but the colors are by no means so pronounced as in either L. glischra or L. kauffmanii." Unfortunately, the author provided no microscopic character data—simply saying that these characters were "as given for var. typica [sic]."

Microscopic characters for the present taxaon were simply reported to be "as reported for" L. illinita sensu H. V. Smith. The data in question is rather sparse, and the editor believes the original material of the present species must be revised to provide reliable information.
