Hypochnus

Abstract: The Tomentelloideae Svrĉek comprises Tomentella Pat. in the wide sense (i.e. including Tomentellastrum and Pseudotomentella of Svrcek), Caldesiella Sacc. and Kneiffiella Karst. Forty British species of Tomentella are enumerated here, of which T. cladii Wakef. and T. sordida Wakef. are described for the first time. T. pseudo-panrwsa Wakef. nom.nov. is given to a species hitherto recorded as T. pannosa Bourd. & Galz. Bourdot and Galzin identified their plant with Hypochnus pannosus (Berk. & Curt.) Burt, an American species from which it differs principally in the angular, not globose spores. For comparison with Tomentella a description is included of Thelephora terrestris f. resupinata , which may often be identified as a Tomentella . Two species of Caldesiella and one of Kneiffiella are recorded. In addition to the two new species the following are new British records: T. submollis, macrospora, subclavigera, viridula, subtestacea, cetvina, puberula, subcervina, livida, hydrophila, microspora, jaapii, gibbosa, avellanea, litschaueri, testaceo-gilva, pseudopannosa, pilosa, subpilosa, subrubiginosa, atrovirens, spongiosa, bresadolae and bourdotii .

Abstract: SUMMARY A new genus of the Corticiaceae, Lazulinospora, is proposed to accommodate Lazulinospora cyanea and Lazulinospora wakefieldii. The primary taxonomic characters of the genus are the septate, hyaline to pale yellow hyphae, without clamps, and subglobose to ovoid ornamented spores that become blue in 2% KOH. Specimens of Tomentella atrocyanea, whose spores also become blue in alkali solution, were recently found in Arizona. These specimens possess characters which adequately demonstrate the affinities of T. atrocyanea with the genus Pseudotomentella, but not with Lazulinospora, and the new combination, Pseudotomentella atrocyanea, is proposed. While collecting in central Florida in 1972, one of us (HHB) collected a specimen which resembled Hypochnus cyaneus Wakef. and Tomentella atrocyanea Wakef. in that it possessed spores whose walls became blue in aqueous 2% KOH and other strongly alkaline solutions. A comparison of the type specimens of the above two names with the material from Florida indicated that the latter was not conspecific with either of them. A search for a published description indicated that the fungus was undescribed; therefore, we propose the Florida species as new.
