SUBSECTION CAMAROPHYLLOPSIS 63
Fig. 15. H. subviolaceus
17516, 17995. AUSTRIA: Moser, Oct. 6, 1948 (Hesler 24128).
OBSERVATIONS-Notes on Peck's type: spores 7-8(9) x 4.5-6 t,
ellipsoid, to ovoid, smooth, yellowish in Melzer's reagent. Basidia
42-48 x 6-8 E/, 2- and 4-spored. Pleurocystidia and cheilocystidia
none. Gill trama intricately interwoven, hyphae 3-7 ft broad. Cuticle of
colorless, gelatinous hyphae. Clamp connections present on the cuticular hyphae. The pileus in the dried state is "sayal brown" to "verona
Although Peck (1901) and Murrill (1916) assigned H. subviolaceus to the section Hygrophorus (Limacium), it is clear that it
is a Camarophyllopsis. Hygrophorus caerulescens Berk. & Curt., collected by Sprague in New England, is similar to H. subviolaceus in
appearance; however, a study of the type H. caerulescens shows that,
having a subparallel gill trama, it is a member of the section Hygrocybe; or possibly it is a member of section Hygrophorus in which, on
revived sections, the hyphae of the gill trama do not regain their
The pellicle of the pileus may not always be bitter. Overholts sent
us specimens from Pennsylvania which apparently had no distinctive
taste but otherwise seem to belong here. In the 2-spored form from
Washington, the taste was very slight. Since Peck did not mention the
taste in his original account, we cannot be sure the type was bitter.
Ricken's H. colemannianus is very likely the 2-spored form of H.
subviolaceus. He gives the spore size as 8-9 x 6-7 pt which is exactly
the same as in the 2-spored form collected in Washington.
