“…Subsequently, L. cornimaris was described and proposed as the generic type by von Hohnel (26). Comparing morphological features of our fungus with the type description strongly suggests that the fungus in ques tion is conspecific with that of von Hohnel, because their ascus, ascospore, apothecium, and spermatium dimensions; cultural char acteristics; and growth patterns all overlap (2,4,26,27).

“…cies in the genus similar to our fungus, such as L. jasmini and L. hicorae, are differentiated from our fungus by differences in col oration of apothecial stipes, colony growth characteristics, and documented host range (27). Previous work has examined the crystal secretions and found mycoparasitic properties in the genus Lambertella (4,(14)(15)(16)29). In 1951, Wood (29) discovered L. comimaris's antagonistic properties against fungi and bacteria such as B. cinerea, Staphylococcus aureus, and Mycobacterium phlei.…”

Wiseman, M. S., Dugan, F. M., Kim, Y. K., and Xiao, C. L. 2015. A postharvest fruit rot of apple caused by Lambertella corni-maris in Washington State. Plant Dis. 99:201-206.During surveys for postharvest diseases of apple conducted in Wash ington State, an unknown fruit rot was observed on stored apple fruit collected from commercial fruit packinghouses. This disease was pre sent in 66 of the 179 grower lots sampled, accounting for an average 1 to 3% of the total decayed fruit sampled. The disease appeared to origi nate from infection of wounds on the fruit skin. Lesions were brown and decayed tissues were spongy. A Lambertella sp. was consistently isolated from the decayed fruit. Sequences of the fungus and those of Lambertella corni-maris in GenBank differed by 0 to 4 bp across the combined small ribosomal subunit + internal transcribed spacer + large ribosomal subunit regions with a maximum identity ranging from 99 to 100%. The fungus grew at 0 to 20°C and formed apothecia on artificial media after 8 to 24 weeks. On potato dextrose agar under a 12-h photoperiod, apothecial dimensions were variable, ranging from 1 to 6 mm in diameter with stipes of 1 to 4 by 0.5 mm. Asci were 76 to 125 by 3.5 to 5.5 pm, inoperculate, eight-spored, clavate, and narrowed at the base. Ascospores were aseptate, 7 to 10 by 2.5 to 4.5 pm, uniseriate to biseriate, and orange-brown at maturity in the ascus. Colony char acteristics included little or no aerial mycelium, dark-yellow to grayblack mycelium, gray-black pseudosclerotia, and yellow pigmentation in the agar. Morphological characteristics of the fungus overlapped with the description of L. corni-maris. 'Fuji' apple fruit that were wounded, inoculated with representative isolates, and incubated at 0°C yielded the same symptoms as seen in packinghouses, and the fungus was reisolated from the diseased fruit. This is the first report of a fruit rot in stored apple caused by L. corni-maris in the United States. We propose Lambertella rot as the name of this disease.

“…Our isolate (MFLU 23-0090) resembles the type species of Lambertella aurantiaca (BHUPP 223) by encompassing stalked apothecia with deep cadmium yellow color receptacle, cylindrical asci, and brown, ellipsoid ascospores (Tewari and Pant 1967, Fig.2-3). The identity was also con rmed by a chemical test using 2% KOH on the apothecial receptacle of MFLU23-0090, which resulted in a color change from cadmium to Lambertella fusoidea Lestari & Chethana, sp. nov. Mycobank number: MB 849025, Facesoffungi number: FoF 14253 (Figs.…”

“…Additionally, the ectal excipulum of L. fusoidea comprises textura angularis-prismatica cells, whereas they are textura prismatica-porrecta in L. aurantiaca and L. takensis. Hence, based on morphology and phylogeny, L. fusoidea (MFLU23-0086) is introduced as a new species. Lambertella phanensis Lestari & Chethana, sp.…”

During our excursions for discomycetes from 2019–2021 in forests and plantations in northern Thailand, several Lambertella-like specimens were found. Morphological observation and BLAST sequence data search confirmed that six newly collected specimens belong to Lambertella. Further phylogenetic analysis using maximum likelihood and Bayesian inference analyses based on combined ITS and LSU sequence data and morphological examination coupled with chemical reactions, confirmed six Lambertella species. Lambertella aurantiaca was established as a new geographical record, and the other five specimens, L. fusoidea, L. phanensis, L. sessilis, L. takensis, and L. tectonae were introduced as novel species. The highlight of the current study is to contribute a complete morphological description of Lambertella aurantiaca since its introduction in 1964, emend the morphological criteria for Lambertella sensu stricto, and provide sequence data for all the Lambertella species described in the current study, including the extant species, L. aurantiaca for the first time, which are essential for future studies.

Achlya recurva. Cultures were placed in darkness and in diffuse daylight on top of a laboratory table at approximately the same temperature. They were examined after 72 hours. Dark cultures were then left in daylight for an additional 72 hours. Light was necessary for the germination of zygotes. (Ziegler, A. W. , 1948). Albugo occidentalis. Hanging-drop slides of conidia were arranged in a chamber at 12°C so that light from a 3-cell flashlight fell on them, while others were placed in the dark. Results after 48 hours showed that spores germinated equally well in light or darkness, (Raabe, R. D,, and G. S. Pound, 1952). Allomyces arbuscula. Cultures exposed to darkness for 7 days and to diurnal illumination for the same period formed zones under both conditions. (Hatch, W. R, , 1936). Blakeslea trispora. Sporangia formed profusely in bright light, subdued light, and total darkness. The shortest sporangiophores were produced in bright light. During their development the sporangiophores were distinctly phototropic. (Weber, G, F. , and F, A, Wolf, 1927). Blastocladiella emersonii. A normal strain and a carotenoid-bearing mutant grew more rapidly in light than in darkness. Illumination induced an increase in CO2 fixation and concomitantly a large increase in the labeled succinate and a decrease in the labeled ketoglutarate pools in the organism. Both labeled and unlabeled glucose were consumed more rapidly in the light than in the dark. Cell-free preparations mediated an enzymatic TPN-dependent oxidation of isocitrate which was inhibited by bicarbonate and light. These same preparations mediated an enzymatic oxidation of reduced TPN which was accelerated by ketoglutarate and bicarbonate; simultaneously, ketoglutarate was carboxylated. These reactions were further accelerated by light. The mechanism of the effect of illumination was tentatively interpreted in terms of a lightstimulated cyclic process, the S.K.I, cycle. This involved carboxylation of ketoglutarate, via isocitric dehydrogenase and perhaps citritase, to succinate and oxalate, and the further carboxylation of some of the succinate to yield ketoglutarate once again. (Cantino, E. C. , and E. A. Horenstein, 1956). Blastocladiella emersonii. Submerged, liquid cultures proliferated more rapidly and produced greater yields of plant material in white light than in darkness. Illuminated, growing cultures of orange plants grew more rapidly in bicarbonate media and fixed more CO2 per unit weight of organism produced, than those incubated in darkness. The quantity of light necessary to induce the effect was not high. The degree of stimulation rose linearly with increasing intensity to about 100 f. c. which yielded maximum results; further increase in intensity up to 300 f. c. neither stimulated nor inhibited. The effective spectrum was in the range of 400-500 m^.
