Physalacria pseudotropica Berthier 1985

New Zealand: Mt. Mizery Track along Bald Hill Road in Longwood Forest between Invercargill and Te Anau, South Island, on decaying unidentified wood, Mar. 1, 1992, coll. Y. Doi TNS-F-171685 (TNS); Taupo, Kaimanawa State Forest Park, Kiko Road, North Island, on decaying unidentified wood, May 7,1987, coll. Y. Doi, TNS-F-101517 (TNS).
Basidiomata 0.7-3.0mm tall, stipitate-capitate. Capitulum 0.3-1.5mm diameter, hollow, globose to subglobose, pruinose, grayish-orange after drying. Resinous exudates on apex of hymenial cystidia were observed under the stereoscope. Stipe 0.4-2.0 X 0.06-0.08 mm, central, cylindrical, with pruinose cushion at the base. Basidiospores 3.8-5.9 X 2.3-3.4 um {x = 4.9 ± 0.5 X 2.9 ± 0.3 um; Q = 1.3-2.1; Q = 1.7 ± 0.2; n = 25), oblong to lacrymoid, smooth, hyaline, thin walled, inamyloid. Basidia 15-25 X 3.5-5.0 µm, narrowly clavate, 4-spored or rarely 2-spored; sterigmata 2.5-3.5 um long. Basidioles cylindrical to fusiform. Hymenial gloeocystidia 35-95 X 10-19 um, cylindrical to fusiform, obtuse or subcapitate, with resinous exudates adherent to the apex, projecting up to 35 um beyond hymenial cells; resinous exudates persist after drying, insoluble in Melzer's reagent, and gradually soluble in 3% KOH. Subhymenial hyphae 2-4 urn diameter, subagglutinate - to interwoven sparsely, cylindrical, hyaline, thin walled, inamyloid. Lower portion of capitulum composed of a hymeniform layer of fusiform to narrowly lageniform, sometimes rostrate cells; the cells hyaline, thin walled, inamyloid. Stipe tissue monomitic; cortical hyphae 2-4 µm diameter, parallel, cylindrical, smooth, hyaline, thin walled, inamyloid; medullary hyphae 2-6 um diameter, otherwise similar to cortical hyphae. Stipe base with scattered, curled, and thin to slightly thick walled (up to 0.8 um diameter) hyphal outgrowths up to 40 µm long and 1.5-3.0µm diameter. Caulocystidia abundant, conical to fusiform, subcapitate at the apex, with resinous exudates adherent to the apex; conical caulocystidia 17-37 X 12-23 um; fusiform caulocystidia 30-65 X 9-16 um. Clamp connections present on the hyphae in all tissues except some stipe tissues.
New Zealand.
Caespitose to solitary on decaying wood.

Specimens TNS-F-171685, -101517 accord well with P. pseudotropica in having a combination of small baisiospores (3.8-5.9 X 2.3-3.4nm), subcapitate hymenial gloeocystidia, and caulocystidia.
Physalacria pseudotropica was only reported from Gisborne (North Island) in New Zealand (Berthier 1985). In this report this fungus is recorded from South Island in New Zealand for the first time.
Resinous exudates of TNS-F-171685, -101517 were observed not only in water but also in Melzer's reagent and 3% KOH. Moreover, these were not soluble in water or Melzer's reagent. Persistence of resinous exudates in P. pseudotropica was not mentioned in the original description.

taxonomic status
Sequence data cleary shows P. pseudotropica is within the single broad clade including P. sinensis and the morphology also supports that. If not treated as a single taxon then P. sinensis repersents two species independent of P. pseudotropica [JAC]
typification
