Description:Sparassis crispa Wulf.: Fr., Syst. Mycol. 1:464. 1821.
There is no Wulfen specimen available in UPS. Only one specimen of Fries' at UPS is labeled S. crispa. It was collected by Th. M. Fries in 1869, so it was not available to Fries when he sanctioned S. crispa. We are now attempting to decide on an appropriate specimen to serve as neotype. When those studies are complete, S. crispa will be neotypified.
In the interim, the Fries specimen will represent the present concept of S. crispa. It possesses small, pale to cream-colored and azonate, flabellae extending from the central core of the basidiocarp. Hyphae system monomitic. Tramal hyphae 4-15 :m diam, thin- to somewhat thick-walled, mostly clamped, with scattered broad refractive hyphae up to 15 :m diam; basidiospores broadly ellipsoid, sometimes flattened adaxially, thin-walled, hyaline, 5.5-6 :m diam, with a large central guttule.
Specimens examined: As S. crisp a--Sweden: Uppsala, Kungsparken, 1869. Th. M. Fries (UPS). As S. radicata Holotype, U.S.A.: Idaho; Priest River, Sept. 1916, on roots of Douglas-fir [Pseudotsuga menziesiij, Weir 9822; Sept. 29, 1966, on P . menziesii, OKM 4817 (both CFMR) Oregon; Detroit Nov. 1, 1909, on P. menziesii, FP 1758 (CFMR).
Many authors list basidiospore lengths of 5-7 :m or 6-7 :m. Our study of collections from North America, Europe, and Japan confirms a range of 5-6.5 :m, excluding the apiculus. We were unable to find longer spores. This is important because S. spathulata basidiospores are 6-8 (-9) :m long with a mean of 7 :m. It is possible, therefore, to separate the two species on spore length alone in poorly preserved specimens.
Excellent illustrations of S. crispa basidiocarps are found in Dahncke and Dahncke (1979) and Jahn (1979), and under S. radicata in Martin and Gilbertson (1976) and Miller (1972). However, only Martin and Gilbertson (1976) pictures the radicating base, characteristic of this species. It is not a characteristic feature of S. spathulata.
