In his revision of the Agaricales of New Zealand, Horak (1971) appears to have been
confused by the same epithet having been applied by Stevenson (1964) to two pleurotoid
fungi, namely Lentinellus crawfordii and Resupinatus crawfordii. In his list, Horak
(1971) cited Resupinatus (Lentinellus) crawfordii, seeming to indicate that he-
considered the two species to be the same. He noted that `the identification of Stevenson
cannot be confirmed because carpophores of the type material are sterile. As shown above,
Lentinellus crawfordii is easily recognised and a good species. However, the type material
of R. crawfordii (Stevenson 718, on fallen Nothofagus menziesii, Nelson, A. Crawford,
6. vii. 1949, K) is certainly in a poor state, and little detail of the hymenium could be
gleaned. Spores were found, however, which were short cylindric to slightly allantoid and
strongly amyloid, and there were densely staining amyloid remains of spores clinging to the
hymenium. The cheilocystidia and pleurocystidia are difficult to determine accurately, but the
lamellar edge is sterile and appears to consist of short, clavate cheilocystidia. The trama is
dense, of more or less parallel, thickish-walled hyphae of 3-5 µm diameter. The
subhymenium is cellular, very densely compacted of narrow, somewhat thick-walled hyphae.
The context is of very narrow (2-3 µm in diameter), loosely interwoven hyphae with large
clamp connections. The pileipellis appears to be only little differentiated, with repent hyphae
with coiled, slightly inflated hyphal endings. The stipe is short and stout, with distinctly
velvety to fibrillose surface. The fibrils are made up of bundles of narrow hyphae, or the
surface of the stipe may be covered with short caulocystidia. The fungus can be readily
identified as a species of Panellus. The size of the spores, the absence of distinctive
cheilocystidia, and the thin-walled pileipellis as well as the more robust form of the
basidiome distinguish it from Panellus stypticus (Bull.: Fr.) P. Karst. which is also present
in New Zealand and described by Petersen and Bennudes (1992).
The new combination proposed for this fungus is as follows: Panellus crawfordii (Stevenson)

Description: Pileus 2.5-3.5 µm diam., reddish brown, orbicular to ovate with downrolled margin, subfibrillose; flesh concolorous, tough gelatinous. Gills decurrent, moderately crowded, shallow, fawn. Stipe 0.5-1 x 0.2-0.7 cm, lateral or markedly excentric, concolorous, velutinate. Spores 7-8 µm diam., non-amyloid, globose, thin-walled (Fig. 47). Hymenophoral trama, 1 µm cuticle of loosely woven, partly gelatinized hyphae. Spors smooth.
Habitat: On fallen Nothofagus menziesii. Nelson, 6.7.1949, A. Crawford in Stevenson (type).

Notes: The identification of Stevenson cannot be confirmed because carpophores of the
type material are sterile.
